Safety Instructions For Repairs
Safety regulations require that during a repair:
• Due to the ‘hot’ parts of this chassis, the set must be
connected to the AC power via an isolation transformer.
• Safety components, indicated by the symbol h, should be
replaced by components identical to the original ones.
• When replacing the CRT, safety goggles must be worn.
Safety regulations require that after a repair, the set must be
returned in its original condition. Pay particular attention to the
following points:
• General repair instruction: as a strict precaution, we advise
you to re-solder the solder connections through which the
horizontal deflection current is flowing, in particular:
– all pins of the line output transformer (LOT)
– fly-back capacitor(s)
– S-correction capacitor(s)
– line output transistor
– pins of the connector with wires to the deflection coil
– other components through which the deflection current
flows.
Note: This re-soldering is advised to prevent bad connections
due to metal fatigue in solder connections and is therefore only
necessary for television sets more than two years old.
• Route the wire trees and EHT cable correctly and secure
them with the mounted cable clamps.
• Check the insulation of the AC power cord for external
damage.
• Check the strain relief of the AC power cord for proper
function, to prevent the cord from touching the CRT, hot
components, or heat sinks.
• Check the electrical DC resistance between the AC plug
and the secondary side (only for sets that have an isolated
power supply). Do this as follows:
1. Unplug the AC power cord and connect a wire between
the two pins of the AC plug.
2. Turn on the main power switch (keep the AC power
cord unplugged!).
3. Measure the resistance value between the pins of the
AC plug and the metal shielding of the tuner or the
aerial connection of the set. The reading should be
between 4.5 MΩ and 12 MΩ.
4. Switch the TV OFF and remove the wire between the
two pins of the AC plug.
• Check the cabinet for defects, to prevent the possibility of
the customer touching any internal parts.

Figure 2-1
•
•
•
•
•
All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD) w. Careless handling
during repair can reduce life drastically. When repairing,
make sure that you are connected with the same potential
as the mass of the set by a wristband with resistance. Keep
components and tools also at this potential. Available ESD
protection equipment:
– Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable, and ground cable)
4822 310 10671.
– Wristband tester 4822 344 13999.
Together with the deflection unit and any multi-pole unit,
flat square picture tubes form an integrated unit. The
deflection and the multi-pole units are set optimally at the
factory. Adjustment of this unit during repair is therefore not
recommended.
Be careful during measurements in the high voltage
section and on the picture tube.
Never replace modules or other components while the unit
is switched ON.
When you align the set, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a
circuit becoming unstable.
2.4
Notes
2.4.1
General
•
It is recommended to have a maintenance inspection carried
out by qualified service personnel. The interval depends on the
usage conditions:
• When the set is used under normal circumstances, for
example in a living room, the recommended interval is
three to five years.
• When the set is used in an environment with higher dust,
grease or moisture levels, for example in a kitchen, the
recommended interval is one year.
• The maintenance inspection includes the following actions:
1. Perform the 'general repair instruction' noted above.
2. Clean the power supply and deflection circuitry on the
chassis.
In order to prevent damage to ICs and transistors, avoid all
high voltage flashovers. In order to prevent damage to the
picture tube, use the method shown in Fig. 2-1, to
discharge the picture tube. Use a high voltage probe and a
multi-meter (position VDC). Discharge until the meter
reading is 0 V (after approx. 30 s).
•
•
Measure the voltages and waveforms with regard to the
chassis (= tuner) ground (H), or hot ground (I), depending
on the tested area of circuitry. The voltages and waveforms
shown in the diagrams are indicative. Measure them in the
Service Default Mode (see chapter 5) with a colour bar
signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated
otherwise) and picture carrier at 475.25 MHz for PAL, or
61.25 MHz for NTSC (channel 3).
Where necessary, measure the waveforms and voltages
with (D) and without (E) aerial signal. Measure the
voltages in the power supply section both in normal
operation (G) and in stand-by (F). These values are
indicated by means of the appropriate symbols.
The semiconductors indicated in the circuit diagram and in
the parts lists, are interchangeable per position with the
Directions for Use
•
semiconductors in the unit, irrespective of the type
indication on these semiconductors.

•
2.4.3
All resistor values are in ohms and the value multiplier is
often used to indicate the decimal point location (e.g. 2K2
indicates 2.2 kohm).
Resistor values with no multiplier may be indicated with
either an "E" or an "R" (e.g. 220E or 220R indicates 220
ohm).
All capacitor values are given in micro-farads (µ= x10-6),
nano-farads (n= x10-9), or pico-farads (p= x10-12).
Capacitor values may also use the value multiplier as the
decimal point indication (e.g. 2p2 indicates 2.2 pF).
An "asterisk" (*) indicates component usage varies. Refer
to the diversity tables for the correct values.
The correct component values are listed in the Spare Parts
List. Therefore, always check this list when there is any
doubt.

Lead Free Solder
Philips CE is going to produce lead-free sets (PBF) from
1.1.2005 onwards.
P
•
Figure 2-2 Lead-free logo
This sign normally has a diameter of 6 mm, but if there is less
space on a board also 3 mm is possible.
Regardless of this logo (is not always present), one must treat
all sets from this date onwards according to the following rules.
3. Directions for Use
You can also download this information from the following
websites:
http://www.philips.com/support
http://www.p4c.philips.com
3.
EN 5
Adjust your solder tool so that a temperature around 360°C
- 380°C is reached and stabilised at the solder joint.
Heating time of the solder-joint should not exceed ~ 4 sec.
Avoid temperatures above 400°C, otherwise wear-out of
tips will rise drastically and flux-fluid will be destroyed. To
avoid wear-out of tips, switch “off” unused equipment or
reduce heat.
Mix of lead-free soldering tin/parts with leaded soldering
tin/parts is possible but PHILIPS recommends strongly to
avoid mixed regimes. If not to avoid, clean carefully the
solder-joint from old tin and re-solder with new tin.
Use only original spare-parts listed in the Service-Manuals.
Not listed standard material (commodities) has to be
purchased at external companies.
Special information for lead-free BGA ICs: these ICs will be
delivered in so-called "dry-packaging" to protect the IC
against moisture. This packaging may only be opened
short before it is used (soldered). Otherwise the body of the
IC gets "wet" inside and during the heating time the
structure of the IC will be destroyed due to high (steam)pressure inside the body. If the packaging was opened
before usage, the IC has to be heated up for some hours
(around 90°C) for drying (think of ESD-protection!).
Do not re-use BGAs at all!
For sets produced before 1.1.2005, containing leaded
soldering tin and components, all needed spare parts will
be available till the end of the service period. For the repair
of such sets nothing changes.
In case of doubt whether the board is lead-free or not (or with
mixed technologies), you can use the following method:
• Always use the highest temperature to solder, when using
SAC305 (see also instructions below).
• De-solder thoroughly (clean solder joints to avoid mix of
two alloys).
Caution: For BGA-ICs, you must use the correct temperatureprofile, which is coupled to the 12NC. For an overview of these
profiles, visit the website www.atyourservice.ce.philips.com
(needs subscription, but is not available for all regions)
You will find this and more technical information within the
"Magazine", chapter "Workshop information".
For additional questions please contact your local repair help
desk.
b
Due to lead-free technology some rules have to be respected
by the workshop during a repair:
• Use only lead-free soldering tin Philips SAC305 with order
code 0622 149 00106. If lead-free solder paste is required,
please contact the manufacturer of your soldering
equipment. In general, use of solder paste within
workshops should be avoided because paste is not easy to
store and to handle.
• Use only adequate solder tools applicable for lead-free
soldering tin. The solder tool must be able
– To reach at least a solder-tip temperature of 400°C.
– To stabilise the adjusted temperature at the solder-tip.
– To exchange solder-tips for different applications.

Practical Service Precautions
•
•
It makes sense to avoid exposure to electrical shock.
While some sources are expected to have a possible
dangerous impact, others of quite high potential are of
limited current and are sometimes held in less regard.
Always respect voltages. While some may not be
dangerous in themselves, they can cause unexpected
reactions that are best avoided. Before reaching into a
powered TV set, it is best to test the high voltage insulation.
It is easy to do, and is a good service precaution.

Service Modes
How to enter SDM
Use one of the following methods:
• Use a standard customer RC-transmitter and key in the
code ‘062596’ directly followed by the MENU button or
• Short wires 9631 and 9641 on the mono carrier (see Fig. 81) and apply Mains voltage. Then press the power button
(remove the short after start-up). Caution: Entering SDM
by shorten wires 9631 and 9641 will override the +8Vprotection. Do this only for a short period. When doing this,
the service-technician must know exactly what he is doing,
as it could lead to damaging the set.
• Or via ComPair.
Service Default Mode (SDM) and Service Alignment Mode
(SAM) offer several features for the service technician, while
the Customer Service Menu (CSM) is used for communication
between dealer and customer.
There is also the option of using ComPair, a hardware interface
between a computer (see requirements) and the TV chassis. It
offers the ability of structured trouble shooting, error code
reading and software version readout for all L01 chassis.
Minimum requirements: a 486 processor, Windows 3.1 and a
CD-ROM drive. A Pentium Processor and Windows 95/98 are
also acceptable (see also paragraph 5.4).

Problems and Solving Tips (Related To CSM)
5.3.1
Picture Problems
Customer Service Mode (CSM)
Purpose
When a customer is having problems with his TV-set, he can
call his dealer. The service technician can than ask the
customer to activate the CSM, in order to identify the status of
the set. Now, the service technician can judge the severness of
the complaint. In many cases, he can advise the customer how
to solve the problem, or he can decide if it is necessary to visit
the customer.
The CSM is a read only mode, therefore modifications in this
mode are not possible.

Service Modes, Error Codes, and Fault Finding
•
Automatic (by communication with the television): ComPair
can automatically read out the contents of the entire error
buffer. Diagnosis is done on I2C level. ComPair can access
the I2C bus of the television. ComPair can send and
receive I2C commands to the micro controller of the
television. In this way, it is possible for ComPair to
communicate (read and write) to devices on the I2C busses
of the TV-set.
• Manually (by asking questions to you): Automatic
diagnosis is only possible if the micro controller of the
television is working correctly and only to a certain extend.
When this is not the case, ComPair will guide you through
the faultfinding tree by asking you questions (e.g. Does the
screen gives a picture? Click on the correct answer: YES/
NO) and showing you examples (e.g. Measure test-point I7
and click on the correct oscillogram you see on the
oscilloscope). You can answer by clicking on a link (e.g.
text or a waveform picture) that will bring you to the next
step in the faultfinding process.
By a combination of automatic diagnostics and an interactive
question/answer procedure, ComPair will enable you to find
most problems in a fast and effective way.
No channel/pre-set is stored at this program number. Go to
the INSTALL menu and store a proper channel at this
program number.
The tuner is faulty (in this case the CODES line will contain
error number 10). Check the tuner and replace/repair if
necessary.
Snowy picture and/or unstable picture
• A scrambled or decoded signal is received.
Black and white picture
Increase the COLOR value when:
• The picture improves after you have pressed the ‘Smart
Picture’ button on the remote control.
• The picture improves after you have switched on the
Customer Service Mode
The new ‘Personal’ preference value is automatically stored.
Menu text not sharp enough
Decrease the CONTRAST value when:
• The picture improves after you have pressed the ‘Smart
Picture’ button on the remote control.
• The picture improves after you have switched on the
Customer Service Mode
The new ‘Personal’ preference value is automatically stored.
5.3.2
Beside fault finding, ComPair provides some additional
features like:
• Up- or downloading of pre-sets.
• Managing of pre-set lists.
• Emulation of the (European) Dealer Service Tool (DST).
• If both ComPair and SearchMan (Electronic Service
Manual) are installed, all the schematics and the PWBs of
the set are available by clicking on the appropriate
hyperlink. Example: Measure the DC-voltage on capacitor
C2568 (Schematic/Panel) at the Monocarrier.Click on the
‘Panel’ hyperlink to automatically show the PWB with a
highlighted capacitor C2568. Click on the ‘Schematic’
hyperlink to automatically show the position of the
highlighted capacitor.
Sound Problems
No sound or sound too loud (after channel change/
switching on)
Increase/decrease the VOLUME level when the volume is OK
after you switched on the CSM. The new ‘Personal’ preference
value is automatically stored.

ComPair
5.4.1
Introduction
ComPair (Computer Aided Repair) is a service tool for Philips
Consumer Electronics products. ComPair is a further
development on the European DST (service remote control),
which allows faster and more accurate diagnostics. ComPair
has three big advantages:
• ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you
systematically through the repair procedures.
• ComPair allows very detailed diagnostics (on I2C level) and
is therefore capable of accurately indicating problem areas.
You do not have to know anything about I2C commands
yourself because ComPair takes care of this.
• ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the
microprocessor is working) and all repair information is
directly available. When ComPair is installed together with
the SearchMan electronic manual of the defective chassis,
schematics and PWBs are only a mouse click away.
5.4.2
5.4.3
How To Connect
1. First install the ComPair Browser software (see the Quick
Reference Card for installation instructions).
2. Connect the RS232 interface cable between a free serial
(COM) port of your PC and the PC connector (marked with
‘PC’) of the ComPair interface.
3. Connect the Mains voltage adapter to the supply connector
(marked with ‘POWER 9V DC’) on the ComPair interface.
4. Switch the ComPair interface OFF.
5. Switch the television set OFF (remove the Mains voltage).
6. Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface
(marked with ‘I2C’) and the ComPair connector on the
mono carrier (see figure 8-1 suffix D).
7. Plug the Mains voltage adapter in the Mains voltage outlet
and switch on the interface. The green and red LEDs light
up together. The red LED extinguishes after approx. 1
second while the green LED remains lit.
8. Start the ComPair program and read the ‘introduction’
chapter.
Specifications
ComPair consists of a Windows based faultfinding program
and an interface box between PC and the (defective) product.
The ComPair interface box is connected to the PC via a serial
or RS232 cable.
In case of the L01 chassis, the ComPair interface box and the
TV communicate via a bi-directional service cable via the
service connector (located on the Main panel, see also figure
8-1 suffix D).
PC
The ComPair faultfinding program is able to determine the
problem of the defective television. ComPair can gather
diagnostic information in two ways:

How to Read the Error Buffer
Use one of the following methods:
• On screen via the SAM (only if you have a picture).
Examples:
– ERROR: 0 0 0 0 0 : No errors detected
– ERROR: 6 0 0 0 0 : Error code 6 is the last and only
detected error

ERROR: 9 6 0 0 0 : Error code 6 was first detected and
error code 9 is the last detected (newest) error
Via the blinking LED procedure (when you have no
picture). See next paragraph.
Via ComPair.
How to Clear the Error Buffer
The error code buffer is cleared in the following cases:
• By activation of the CLEAR command in the SAM menu:
• When you exit SDM/SAM with the STANDBY command on
the remote control (when leaving SDM/SAM, by
disconnecting the set from Mains voltage, the error buffer
is not reset).
• When you transmit the command DIAGNOSE-99-OK with
ComPair.
• If the content of the error buffer has not changed for 50
hours, it resets automatically.
Error Buffer
The error code buffer contains all detected errors since the last
time the buffer was erased. The buffer is written from left to
right. When an error occurs that is not yet in the error code
buffer, it is written at the left side and all other errors shift one
position to the right.

Error Codes
In case of non-intermittent faults, clear the error buffer before
you begin the repair. These to ensure that old error codes are
no longer present.
If possible, check the entire contents of the error buffer. In
some situations, an error code is only the result of another error
code and not the actual cause (e.g., a fault in the protection
detection circuitry can also lead to a protection).

Service Modes, Error Codes, and Fault Finding
The Blinking LED Procedure
Via this procedure, you can make the contents of the error
buffer visible via the front LED. This is especially useful when
there is no picture.
When the SDM is entered, the LED will blink the contents of the
error-buffer.
Error-codes ≥ 10 are shown as follows:
– a long blink of 750 ms (which is an indication of the decimal
digit),
– a pause of 1.5 s,
– n short blinks (n = 1 - 9),
– when all the error-codes are displayed, the sequence
finishes with a LED blink of 3 s.,
– the sequence starts again.
Example of error buffer: 12 9 6 0 0
After entering SDM:
– 1 long blink of 750 ms followed by a pause of 1.5 s,
– 2 short blinks followed by a pause of 3 s,
– 9 short blinks followed by a pause of 3 s,
– 6 short blinks followed by a pause of 3 s,
– 1 long blink of 3 s to finish the sequence,
– the sequence starts again.
5.7
Protections
If a fault situation is detected an error code will be generated
and if necessary, the set will be put in the protection mode.
Blinking of the red LED at a frequency of 3 Hz indicates the
protection mode. In some error cases, the microprocessor
does not put the set in the protection mode. The error codes of
the error buffer can be read via the service menu (SAM), the
blinking LED procedure or via ComPair. The DST diagnose
functionality will force the set into the Service-standby, which is
similar to the usual standby mode, however the microprocessor
has to remain in normal operation completely.
To get a quick diagnosis the chassis has three service modes
implemented:
• The Customer Service Mode (CSM).
• The Service Default Mode (SDM). Start-up of the set in a
predefined way.
• The Service Alignment Mode (SAM). Adjustment of the set
via a menu and with the help of test patterns.
See for a detailed description Chapter 9 paragraphs Deflection
and Power Supply.
5.8
Repair Tips
Below some failure symptoms are given, followed by a repair
tip.
• Set is dead and makes hiccuping sound
‘MainSupply’ is available. Hiccuping stops when desoldering L5561, meaning that problem is in the
‘MainSupply’ load. No output voltages at LOT, no
horizontal deflection. Reason: line transistor 7402 is
defective.
• Set is dead, and makes no sound
Check power supply IC7520. Result: voltage at pins 1, 3, 4,
5 and 6 are about 180 V and pin 8 is 0 V. The reason why
the voltage on these pins is so high is because the output
driver (pin 6) has an open load. That is why MOSFET
TS7521 is not able to switch. Reason: feedback resistor
3523 is defective. Caution: be careful measuring on the
gate of TS7521; circuitry is very high ohmic and can easily
be damaged! (first connect ground to measuring
equipment, than the gate).
• Set is in hiccup mode and shuts down after 8 s.
Blinking LED (set in SDM mode) indicates error 5. As it is
unlikely that µP ‘POR’ and ‘+8V protection’ happen at the
•
•
•
same time, measure the ‘+8V’. If this voltage is missing,
check transistor TS7408.
Set is non-stop in hiccup mode
Set is in over current mode; check the secondary sensing
(opto coupler 7515) and the ‘MainSupply’ voltage. Signal
‘Stdby_con’ must be logic low under normal operation
conditions and goes to high (3.3 V) under standby and fault
conditions.
Set turns on, but without picture and sound
The screen shows snow, but OSD and other menus are
okay. Blinking LED procedure indicates error 10, so
problem is expected in the tuner (pos. 1000). Check
presence of supply voltages. As ‘Vlotaux+5V’ at pin 6 and
7 are okay, ‘VT_supply’ at pin 9 is missing. Conclusion:
resistor 3428 is defective.
Set turns on, but with a half screen at the bottom.
Sound is okay
Blinking LED (set in SDM mode) indicates error 2. Check
‘Vlotaux+13V’, ‘+5V’ and ‘+50V’. If they are okay, problem
is expected in the vertical amplifier IC7471. Measure with
a scope the waveform on pin 17 of the UOC. Measure also
at pin 1 of IC7471. If here the signal is missing, a defective
resistor R3244 causes the problem.

General Alignment Conditions
9.
Perform all electrical adjustments under the following
conditions:
• Mains voltage and frequency: according to country’s
standard.
• Connect the set to the Mains via an isolation transformer.
• Allow the set to warm up for approximately 20 minutes.
• Measure the voltages and waveforms in relation to chassis
ground (with the exception of the voltages on the primary
side of the power supply). Never use the cooling fins/plates
as ground.
• Test probe: Ri > 10 MΩ; Ci < 2.5 pF.
• Use an isolated trimmer/screwdriver to perform the
alignments.

BRIGHTNESS to minimum (OSD just visible in a dark
room).
Return to the SAM via the MENU key.
Connect the RF output of a pattern generator to the
antenna input. Test pattern is a 'black' picture (blank
screen on CRT without any OSD info).
Set the channel of the oscilloscope to 50 V/div and the time
base to 0.2 ms (external triggering on the vertical pulse).
Ground the scope at the CRT panel and connect a 10:1
probe to one of the cathodes of the picture tube socket (see
diagram B).
Measure the cut off pulse during first full line after the frame
blanking (see Fig. 8-2). You will see two pulses, one being
the cut off pulse and the other being the white drive pulse.
Choose the one with the lowest value, this is the cut off
pulse.
Select the cathode with the highest VDC value for the
alignment. Adjust the Vcutoff of this gun with the SCREEN
potentiometer (see Fig. 8-1) on the LOT to the correct
value (see table below).
Restore BRIGHTNESS and CONTRAST to normal (= 31).

1. Tune the set to a circle or crosshatch test pattern (use an
external video pattern generator).
2. Choose picture mode NATURAL (or MOVIES) with the
‘SMART PICTURE’ button on the remote control
transmitter.
3. Adjust the FOCUS potentiometer (see Fig. 8-1) until the
vertical lines at 2/3 from east and west, at the height of the
centreline, are of minimum width without visible haze.

How to change an Option Byte
An Option Byte represents a number of different options.
Changing these bytes directly makes it possible to set all
options very fast. All options are controlled via seven option
bytes. Select the option byte (OB1.. OB7) with the MENU UP/
DOWN keys, and enter the new value.
Leaving the OPTION submenu saves changes in the Option
Byte settings. Some changes will only take effect after the set
has been switched OFF and ON with the Mains switch (cold
start).
How to calculate the value of an Option Byte
Calculate an Option Byte value (OB1 .. OB7) in the following
way:
1. Check the status of the single option bits (OP): are they
enabled (1) or disabled (0).
2. When an option bit is enabled (1) it represents a certain
value (see first column ‘value between brackets’ in first
table below). When an option bit is disabled, its value is 0.
3. The total value of an Option Byte is formed by the sum of
its eight option bits. See second table below for the correct
option numbers per typenumber.

Vertical alignment
• Vertical slope (VSL). Align the vertical centre of the
picture to the vertical centre of the CRT. This is the first of
the vertical alignments to perform. For an easy alignment,
set SBL to ON.
• Vertical Amplitude (VAM). Align the vertical amplitude so
that the complete test pattern is visible.
• Vertical S-Correction (VSC). Align the vertical linearity,
meaning that vertical intervals of a grid pattern must be
equal over the entire screen height.
• Vertical Shift (VSH). Align the vertical centring so that the
test pattern is located vertically in the middle. Repeat the
'vertical amplitude' alignment if necessary.
• Service blanking (SBL). Switch the blanking of the lower
half of the screen ON or OFF (to be used in combination
with the vertical slope alignment).
• H60. Align straight horizontal lines if NTSC input (60 Hz) is
used i.s.o. PAL (50 Hz).
No alignments are needed for the audio sub menu. Use the
given default values.

Introduction
The L01 chassis is a global TV chassis for the model year 2001
and is used for TV sets with screen sizes from 14” - 21” (small
screen) to 21” - 32” (large screen).
The standard architecture consists of a Main panel, a Picture
Tube panel, a Side I/O panel (not al executions) and a Top
Control panel.
The Main panel consists primarily of conventional components
with hardly any surface mounted devices.
The L01 is divided into 2 basic systems, i.e. mono and stereo
sound. While the audio processing for the mono sound is done
in the audio block of the UOC, an external audio processing IC
is used for stereo sets.
The tuning system features 100 video channels with on-screen
display. The main tuning system uses a tuner, a
microcomputer, and a memory IC mounted on the main panel.
Also, in some type numbers, an FM radio is implemented with
40 pre-set channels.
The microcomputer communicates with the memory IC, the
customer keyboard, remote receiver, tuner, signal processor IC
and the audio output IC via the I2C bus. The memory IC retains
the settings for favourite stations, customer-preferred settings,
and service/factory data.
The on-screen graphics and closed caption decoding are done
within the microprocessor, and then sent to the signal
processor IC to be added to the main signal.
The chassis uses a Switching Mode Power Supply (SMPS) for
the main voltage source. The chassis has a ‘hot’ ground
reference on the primary side and a cold ground reference on
the secondary side of the power supply and the rest of the
chassis.
Figure 9-1
The functions for video processing, microprocessor (µP) and
teletext (TXT) decoder are combined in one IC (TDA958xH),
the so-called Ultimate One Chip (UOC). This chip is (surface)
mounted on the copper side of the main panel.

Audio Signal Processing
9.2.1
Stereo
In stereo sets, the signal goes via the SAW filter (position 1004
in case of QSS demodulation and 1003 in case of Intercarrier
demodulation), to the audio demodulator part of the UOC
IC7200. The stereo audio output on pin 33 goes, via TS7206,
to the stereo decoder 7831.
The switch inside the stereo decoder 7831 selects (via I2C)
either the internal decoder or an external source.
The NICAM + 2CS AM/FM stereo decoder is an ITT MSP34X5.
The output is fed to the to the audio amplifier (AN7522 at
position 7901). The volume level is controlled at this IC (pin 9)
by a control line (VolumeMute) from the microprocessor. The
audio signal from 7901 is then sent to the speaker/headphone
output panel.

FM radio (if present)
7200
The FM radio uses the 10.7 MHz concept. This SIF frequency
is available at pin 10 of the tuner. Via a pre-amplifier (TS7209
and TS7210), the signal is fed for demodulation to either the
UOC (for mono FM radio) or by the Micronas MSP34X5 (for
stereo FM radio).

Once the signal source is selected, a chroma filter calibration is
performed. The received colour burst sub-carrier frequency is
used for this. Correspondingly, the chroma band pass filter for
PAL processing or the cloche filter for SECAM processing is
switched on. The selected luminance (Y) signal is supplied to
the horizontal and vertical synchronisation processing circuit
and to the luminance processing circuit. In the luminanceprocessing block, the luminance signal goes to the chroma trap
filter. This trap is switched 'on' or 'off', depending on the colour
burst detection of the chroma calibration circuit.
The group delay correction part can be switched between the
BG and a flat group delay characteristic. This has the
advantage that in multi-standard receivers no compromise has
to be made for the choice of the SAW filter.
9.3.4
Video Demodulation
The colour decoder circuit detects whether the signal is a PAL,
NTSC or SECAM signal. The result is made known to the auto
system manager. The PAL/NTSC decoder has an internal
clock generator, which is stabilised to the required frequency
by using the 12 MHz clock signal from the reference oscillator
of the microcontroller/teletext decoder.
The base-band delay line is used to obtain a good suppression
of cross colour effects.
The Y signal and the delay line outputs U and V are applied to
the luminance/chroma signal processing part of the TV
processor.
Video Source Selection
The Composite Video Blanking Signal (CVBS) from buffer
7201 goes to the audio carrier trap filters (1200 and 1201) to
remove the audio signal. The signal then goes to pin 40 of
IC7200. The internal input switch selects the following input
signals:
• Pin 40: terrestrial CVBS input
• Pin 42: external AV1 CVBS input
• Pin 44: external Side I/O CVBS or AV2 Luminance (Y)
input
• Pin 45: external AV2 Chrominance (C) input
42
7831
RF Signal Processing
The incoming RF signal goes to the tuner (pos. 1000), where
the 38.9 MHz IF signal is developed and amplified. The IF
signals then exits the tuner from pin 11 to pass through the
SAW filter (position 1002 in case of QSS demodulation and
1003 in case of Intercarrier demodulation). The shaped signal
is then applied to the IF processor part of the UOC (pos. 7200).
Tuner AGC (Automatic Gain Control) will reduce the tuner gain
and thus the tuner output voltage when receiving strong RF
signals. Adjust the AGC take-over point via the Service
Alignment Mode (SAM). The tuner AGC starts working when
the video-IF input reaches a certain input level and will adjust
this level via the I2C bus. The tuner AGC signal goes to the
tuner (pin 1) via the open collector output (pin 22) of the UOC.
The IC also generates an Automatic Frequency Control (AFC)
signal that goes to the tuning system via the I2C bus, to provide
frequency correction when needed.
The demodulated composite video signal is available at pin 38
and then buffered by transistor 7201.

adaptation of the selected application. The I2C bus is for
defining and controlling the signals.

Luminance/Chrominance Signal Processing
The output of the YUV separator is fed to the internal YUV
switch, which switches between the output of the YUV
separator or the external YUV (for DVD or PIP) on pins 51-53.
Pin 50 is the input for the insertion control signal called ‘FBL-1’.
When this signal level becomes higher than 0.9 V (but less than
3 V), the RGB signals at pins 51, 52 and 53 are inserted into
the picture by using the internal switches.
Also some picture improvement features are implemented in
this part:
• Black stretch This function corrects the black level of
incoming signals, which have a difference between the
black level and the blanking level. The amount of extension
depends upon the difference between actual black level
and the darkest part of the incoming video signal level. It is
detected by means of an internal capacitor.
• White stretch This function adapts the transfer
characteristic of the luminance amplifier in a non-linear way
depending on the average picture content of the luminance
Circuit Description
•
signal. It operates in such a way that maximum stretching
is obtained when signals with a low video level are
received. For bright pictures, stretching is not active.
Dynamic skin tone correction This circuit corrects
(instantaneously and locally) the hue of those colours
which are located in the area in the UV plane that matches
the skin tone. The correction is dependent on the
luminance, saturation and distance to the preferred axis.
The YUV signal is then fed to the colour matrix circuit, which
converts it to R, G and B signals.
The OSD/TXT signal from the microprocessor is mixed with the
main signal at this point, before being output to the CRT board
(pins 56, 57 and 58).
9.3.6
9.3.7
The following additional controls are used:
• Black current calibration loop Because of the 2-point
black current stabilisation circuit, both the black level and
the amplitude of the RGB output signals depend on the
drive characteristics of the picture tube. The system checks
whether the returning measuring currents meet the
requirements, and adapt the output level and gain of the
circuit when necessary. After stabilisation of the loop, the
RGB drive signals are switched on. The 2-point black level
system adapts the drive voltage for each cathode in such a
way that the two measuring currents have the right value.
This is done with the measurement pulses during the frame
flyback. During the first frame, three pulses with a current
of 8 µA are generated to adjust the cut off voltage. During
the second frame, three pulses with a current of 20 µA are
generated to adjust the ‘white drive’. This has as a
consequence, that a change in the gain of the output stage
will be compensated by a gain change of the RGB control
circuit. Pin 55 (BLKIN) of the UOC is used as the feedback
input from the CRT base panel.
• Blue stretch This function increases the colour
temperature of the bright scenes (amplitudes which
exceed a value of 80% of the nominal amplitude). This
effect is obtained by decreasing the small signal gain of the
red and green channel signals, which exceed this 80%
level.
• Beam current limiting A beam current limiting circuit
inside the UOC handles the contrast and brightness control
for the RGB signals. This prevents the CRT from being
overdriven, which could otherwise cause serious damage
in the line output stage. The reference used for this
purpose is the DC voltage on pin 54 (BLCIN) of the TV
processor. Contrast and brightness reduction of the RGB
output signals is therefore proportional to the voltage
present on this pin. Contrast reduction starts when the
voltage on pin 54 is lower than 2.8 V. Brightness reduction
starts when the voltage on pin 54 is less than 1.7 V. The
voltage on pin 54 is normally 3.3 V (limiter not active).
During set switch ‘off’, the black current control circuit
generates a fixed beam current of 1 mA. This current
ensures that the picture tube capacitance is discharged.
During the switch-off period, the vertical deflection is
placed in an over-scan position, so that the discharge is not
visible on the screen.
9.
EN 49
RGB Amplifier
From outputs 56, 57 and 58 of IC7200, the RGB signals are
applied to the analogue output amplifiers on the CRT panel.
The R-signal is amplified by a circuit built around transistors
TS7311, 7312 and 7313, which drives the picture tube
cathodes.
The supply voltage for the amplifier is +160 V and is derived
from the line output stage.
9.4
Synchronisation
Inside IC7200 (part D), the vertical and horizontal sync-pulses
are separated. These ‘H’ and ‘V’ signals are synchronised with
the incoming CVBS signal. They are then fed to the H- and Vdrive circuits and to the OSD/TXT circuit for synchronisation of
the On Screen Display and Teletext (or Closed Caption)
information.
RGB Control
The RGB control circuit enables the picture parameters
contrast, brightness and saturation to be adjusted, by using a
combination of the user menus and the remote control.
Additionally automatic gain control for the RGB signals via cutoff stabilisation is achieved in this functional block to obtain an
accurate biasing of the picture tube. Therefor this block inserts
the cut-off point measuring pulses into the RGB signals during
the vertical retrace period.
L01.2E AB
9.5
Deflection
9.5.1
Horizontal Drive
The horizontal drive signal is obtained from an internal VCO,
which is running at twice the line frequency. This frequency is
divided by two, to lock the first control loop to the incoming
signal.
When the IC is switched ‘on’, the ‘Hdrive’ signal is suppressed
until the frequency is correct.
The ‘Hdrive’ signal is available at pin 30. The ‘Hflybk’ signal is
fed to pin 31 to phase lock the horizontal oscillator, so that
TS7401 cannot switch ‘on’ during the flyback time.
The ‘EWdrive’ signal for the E/W circuit (if present) is available
on pin 15, where it drives transistor 7400 to make linearity
corrections in the horizontal drive.
When the set is switched on, the ‘+8V’ voltage goes to pin 9 of
IC7200. The horizontal drive starts up in a soft start mode. It
starts with a very short TON time of the horizontal output
transistor. The TOFF of the transistor is identical to the time in
normal operation. The starting frequency during switch on is
therefore about 2 times higher than the normal value. The ‘on’
time is slowly increased to the nominal value in 1175 ms. When
the nominal value is reached, the PLL is closed in such a way
that only very small phase corrections are necessary.
The ‘EHTinformation’ line on pin 11 is intended to be used as a
‘X-ray’ protection. When this protection is activated (when the
voltage exceeds 6 V), the horizontal drive (pin 30) is switched
'off' immediately. If the ‘H-drive’ is stopped, pin 11 will become
low again. Now the horizontal drive is again switched on via the
slow start procedure.
The ‘EHTinformation’ line (Aquadag) is also fed back to the
UOC IC7200 pin 54, to adjust the picture level in order to
compensate for changes in the beam current.
The filament voltage is monitored for ‘no’ or ‘excessive’ voltage.
This voltage is rectified by diode 6413 and fed to the emitter of
transistor 7405. If this voltage goes above 6.8 V, transistor
7405 will conduct, making the ‘EHT0’ line ‘high’. This will
immediately switch off the horizontal drive (pin 30) via the slow
stop procedure.
The horizontal drive signal exits IC7200 at pin 30 and goes to
7401, the horizontal driver transistor. The signal is amplified
and coupled to the base circuit of 7402, the horizontal output
transistor. This will drive the line output transformer (LOT) and
associated circuit. The LOT provides the extra high voltage
(EHT), the VG2 voltage and the focus and filament voltages for
the CRT, while the line output circuit drives the horizontal
deflection coil.

Circuit Description
L01.2E AB
Vertical Drive
A divider circuit performs the vertical synchronisation. The
vertical ramp generator needs an external resistor (R3245, pin
20) and capacitor (C2244, pin 21). A differential output is
available at pins 16 and 17, which are DC-coupled with the
vertical output stage.
To avoid damage of the picture tube when the vertical
deflection fails, the ‘V_GUARD’ output is fed to the beam
current limiting input. When a failure is detected, the RGBoutputs are blanked. When no vertical deflection output stage
is connected, this guard circuit will also blank the output
signals.
These ‘V_DRIVE+’ and ‘V_DRIVE-‘ signals are applied to the
input pins 7 and 1 of IC7471 (vertical deflection amplifier).
These are voltage driven differential inputs. As the driver
device (IC7200) delivers output currents, R3474 and R3479
convert them to voltage. The differential input voltage is
compared with the voltage across measuring resistor R3471
that provides internal feedback information. The voltage across
this measuring resistor is proportional to the output current,
which is available at pin 5 where it drives the vertical deflection
coil (connector 0222).
IC7471 is supplied by +/-13 V. The vertical flyback voltage is
generated at pin 3.

Introduction
The supply is a Switching Mode Power Supply (SMPS). The
frequency of operation varies with the circuit load. This ‘QuasiResonant Flyback’ behaviour has some important benefits
compared to a ‘hard switching’ fixed frequency Flyback
converter. The efficiency can be improved up to 90%, which
results in lower power consumption. Moreover the supply runs
cooler and safety is enhanced.
The power supply starts operating when a DC voltage goes
from the rectifier bridge via T5520, R3532 to pin 8. The
operating voltage for the driver circuit is also taken from the
‘hot’ side of this transformer.
The switching regulator IC7520 starts switching the FET ‘on’
and ‘off’, to control the current flow through the primary winding
of transformer 5520. The energy stored in the primary winding
during the ‘on’ time is delivered to the secondary windings
during the ‘off’ time.
The ‘MainSupply’ line is the reference voltage for the power
supply. It is sampled by resistors 3543 and 3544 and fed to the
input of the regulator 7540/6540. This regulator drives the
feedback optocoupler 7515 to set the feedback control voltage
on pin 3 of 7520.
The power supply in the set is ‘on’ any time AC power goes to
the set.
Derived Voltages
The voltages supplied by the secondary windings of T5520 are:
• ‘MainAux’ for the audio circuit (voltage depends on set
execution, see table below),
• 3.3 V and 3.9 V for the microprocessor and
• ‘MainSupply’ for the horizontal output (voltage depends on
set execution, see table below).
Other supply voltages are provided by the LOT. It supplies +50
V (only for large screen sets), +13 V, +8 V, +5 V and a +200 V
source for the video drive. The secondary voltages of the LOT
are monitored by the ‘EHTinformation’ lines. These lines are
fed to the video processor part of the UOC IC7200 on pins 11
and 34.
This circuit will shut ‘off’ the horizontal drive in case of overvoltage or excessive beam current.

Degaussing
When the set is switched on, the degaussing relay 1515 is
immediately activated as transistor 7580 is conducting. Due to
the RC-time of R3580 and C2580, it will last about 3 to 4

Basic IC Functionality
For a clear understanding of the Quasi-Resonant behaviour, it
is possible to explain it by a simplified circuit diagram (see
Figure below). In this circuit diagram, the secondary side is
transferred to the primary side and the transformer is replaced
by an inductance LP. CD is the total drain capacitance including
the resonance capacitor CR, parasitic output capacitor COSS of
the MOSFET and the winding capacitance CW of the
transformer. The turns ratio of the transformer is represented
by n (NP/NS).
In the Quasi-Resonant mode each period can be divided into
four different time intervals, in chronological order:
• Interval 1: t0 < t < t1 primary stroke At the beginning of the
first interval, the MOSFET is switched ‘on’ and energy is
stored in the primary inductance (magnetisation). At the
end, the MOSFET is switched ‘off’ and the second interval
starts.
• Interval 2: t1 < t < t2 commutation time In the second
interval, the drain voltage will rise from almost zero to
VIN+n•(VOUT +VF). VF is the forward voltage drop of de
diode that will be omitted from the equations from now on.
The current will change its positive derivative,
corresponding to VIN/LP, to a negative derivative,
corresponding to -n•VOUT /LP.
• Interval 3: t2 < t < t3 secondary stroke In the third interval,
the stored energy is transferred to the output, so the diode
starts to conduct and the inductive current IL will decrease.
In other words, the transformer will be demagnetised.
When the inductive current has become zero the next
interval begins.
• Interval 4: t3 < t < t00 resonance time In the fourth interval,
the energy stored in the drain capacitor CD will start to
resonate with the inductance LP. The voltage and current
waveforms are sinusoidal waveforms. The drain voltage
will drop from VIN+n•VOUT to VIN-n•VOUT.
Frequency Behaviour
The frequency in the QR-mode is determined by the power
stage and is not influenced by the controller (important
parameters are LP and CD). The frequency varies with the input
voltage VIN and the output power POUT. If the required output
power increases, more energy has to be stored in the
transformer. This leads to longer magnetising tPRIM and
demagnetising tSEC times, which will decrease the frequency.
See the frequency versus output power characteristics below.
The frequency characteristic is not only output power-, but also
input voltage dependent. The higher the input voltage, the
smaller tPRIM, so the higher the frequency will be.

Point P1 is the minimum frequency fMIN that occurs at the
specified minimum input voltage and maximum output power
required by the application. Of course the minimum frequency
has to be chosen above the audible limit (>20 kHz).
Start-up Sequence
When the rectified AC voltage VIN (via the centre tap connected
to pin 8) reaches the Mains dependent operation level (Mlevel:
between 60 and 100 V), the internal ‘Mlevel switch’ will be
opened and the start-up current source is enabled to charge
capacitor C2521 at the VCC pin as shown below.
The ‘soft start’ switch is closed when the VCC reaches a level of
7 V and the ‘soft start’ capacitor CSS (C2522, between pin 5
and the sense resistor R3526), is charged to 0.5 V.
Once the VCC capacitor is charged to the start-up voltage VCCstart (11 V), the IC starts driving the MOSFET. Both internal
current sources are switched ‘off’ after reaching this start-up
voltage. Resistor RSS (3524) will discharge the ‘soft start’
capacitor, such that the peak current will slowly increase. This
to prevent ‘transformer rattle’.
During start-up, the VCC capacitor will be discharged until the
moment that the primary auxiliary winding takes over this
voltage.
Operation
The supply can run in three different modes depending on the
output power:
• Quasi-Resonant mode (QR) The QR mode, described
above, is used during normal operation. This will give a
high efficiency.
• Frequency Reduction mode (FR) The FR mode (also
called VCO mode) is implemented to decrease the
switching losses at low output loads. In this way the
efficiency at low output powers is increased, which enables
power consumption smaller than 3 W during stand-by. The
voltage at the pin 3 (Ctrl) determines where the frequency
reduction starts. An external Ctrl voltage of 1.425 V
corresponds with an internal VCO level of 75 mV. This
fixed VCO level is called VVCO,start . The frequency will be
reduced in relation to the VCO voltage between 75 mV and
50 mV (at levels larger than 75 mV, Ctrl voltage < 1.425V,
the oscillator will run on maximum frequency foscH = 175
kHz typically). At 50 mV (VVCO,max) the frequency is
reduced to the minimum level of 6 kHz. Valley switching is
still active in this mode.
• Minimum Frequency mode (MinF) At VCO levels below 50
mV, the minimum frequency will remain on 6 kHz, which is
called the MinF mode. Because of this low frequency, it is
possible to run at very low loads without having any output
regulation problems.

Safe-Restart Mode
This mode is introduced to prevent the components from being
destroyed during eventual system fault conditions. It is also
used for the Burst mode. The Safe-Restart mode will be
entered if it is triggered by one of the following functions:
• Over voltage protection,
• Short winding protection,
• Maximum ‘on time’ protection,
• VCC reaching UVLO level (fold back during overload),
• Detecting a pulse for Burst mode,
• Over temperature protection.
τ = RSS⋅CSS
When entering the Safe-Restart mode, the output driver is
immediately disabled and latched. The VCC winding will not
charge the VCC capacitor anymore and the VCC voltage will
drop until UVLO is reached. To recharge the VCC capacitor, the
internal current source (I(restart)(VCC) ) will be switched ‘on’ to
initiate a new start-up sequence as described before. This
Safe-Restart mode will persist until the controller detects no
faults or burst triggers.

Standby
The set goes to Standby in the following cases:
• After pressing the ‘standby’ key on the remote control.
• When the set is in protection mode.
Circuit Description
In Standby, the power supply works in ‘burst mode’.
Burst mode can be used to reduce the power consumption
below 1 W at stand-by. During this mode, the controller is active
(generating gate pulses) for only a short time and for a longer
time inactive waiting for the next burst cycle.
In the active period the energy is transferred to the secondary
and stored in the buffer capacitor CSTAB in front of the linear
stabiliser (see Figure below). During the inactive period, the
load (e.g. microprocessor) discharges this capacitor. In this
mode, the controller makes use of the Safe-Restart mode.

Figure 9-14
The system enters burst mode standby when the
microprocessor activates the ‘Stdby_con’ line. When this line is
pulled high, the base of TS7541 is allowed to go high. This is
triggered by the current from collector TS7542. When TS7541
turns ‘on’, the opto-coupler (7515) is activated, sending a large
current signal to pin 3 (Ctrl). In response to this signal, the IC
stops switching and enters a ‘hiccup’ mode. This burst
activation signal should be present for longer than the ‘burst
blank’ period (typically 30 µs): the blanking time prevents false
burst triggering due to spikes.
Burst mode standby operation continues until the
microcontroller pulls the ‘Stdby_con’ signal low again. The
base of TS7541 is unable to go high, thus cannot turn ‘on’. This
will disable the burst mode. The system then enters the startup sequence and begins normal switching behaviour.
Demagnetisation sense
This feature guarantees discontinuous conduction mode
operation in every situation. The oscillator will not start a new
primary stroke until the secondary stroke has ended. This is to
ensure that FET 7521 will not turn on until the demagnetisation
of transformer 5520 is completed. The function is an additional
protection feature against:
• saturation of the transformer,
• damage of the components during initial start-up,
• an overload of the output.
The demag(netisation) sense is realised by an internal circuit
that guards the voltage (Vdemag) at pin 4 that is connected to
VCC winding by resistor R1 (R3522). The Figure below shows
the circuit and the idealised waveforms across this winding.

For a more detailed description of one burst cycle, three time
intervals are defined:
• t1: Discharge of VCC when gate drive is active During the
first interval, energy is transferred, which result in a rampup of the output voltage (VSTAB) in front of the stabiliser.
When enough energy is stored in the capacitor, the IC will
be switched ‘off’ by a current pulse generated at the
secondary side. This pulse is transferred to the primary
side via the opto coupler. The controller will disable the
output driver (safe restart mode) when the current pulse
reaches a threshold level of 16 mA into the Ctrl pin. A
resistor R1 (R3519) is placed in series with the opto
coupler, to limit the current going into the Ctrl pin.
Meanwhile the VCC capacitor is discharged but has to stay
above VUVLO .
• t2: Discharge of VCC when gate drive is inactive During the
second interval, the VCC is discharged to VUVLO. The output
voltage will decrease depending on the load.
• t3: Charge of VCC when gate drive is inactive The third
interval starts when the UVLO is reached. The internal
current source charges the VCC capacitor (also the soft
start capacitor is recharged). Once the VCC capacitor is
charged to the start-up voltage, the driver is activated and
a new burst cycle is started.

Over Voltage Protection
The Over Voltage Protection ensures that the output voltage
will remain below an adjustable level. This works by sensing
the auxiliary voltage via the current flowing into pin 4 (DEM)
during the secondary stroke. This voltage is a well-defined
replica of the output voltage. Any voltage spikes are averaged
by an internal filter.
If the output voltage exceeds the OVP trip level, the OVP circuit
switches the power MOSFET ‘off’.
Next, the controller waits until the ‘under voltage lock out‘ level
(UVLO = ± 9 V) is reached on pin 1 (VCC). This is followed by a
safe restart cycle, after which switching starts again. This
process is repeated as long as the OVP condition exists. The
output voltage, at which the OVP function trips, is set by the
demagnetisation resistor R3522.
Over Current Protection
The internal OCP protection circuit limits the ‘sense’ voltage on
pin 5 to an internal level.
EN 54
9.
Circuit Description
L01.2E AB
Over Power Protection
During the primary stroke, the rectified AC input voltage is
measured by sensing the current drawn from pin 4 (DEM). This
current is dependent on the voltage on pin 9 of transformer
5520 and the value of R3522. The current information is used
to adjust the peak drain current, which is measured via pin
ISENSE.
9.7.1
Short Winding Protection
If the ‘sense’ voltage on pin 5 exceeds the short winding
protection voltage (0.75 V), the converter will stop switching.
Once VCC drops below the UVLO level, capacitor C2521 will be
recharged and the supply will start again. This cycle will be
repeated until the short circuit is removed (safe restart mode).
The short winding protection will also protect in case of a
secondary diode short circuit.
This protection circuit is activated after the leading edge
blanking time (LEB).
9.7.2
The microprocessor part of the UOC has the complete control
and teletext on board. User menu, Service Default Mode,
Service Alignment Mode and Customer Service Mode are
generated by the µP. Communication to other ICs is done via
the I2C-bus.
9.7.3
The front LED (6691) is connected to an output control line of
the microprocessor (pin 5). It is activated to provide the user
information about whether or not the set is working correctly
(e.g., responding to the remote control or fault condition)

Sound Interface
There are three control signals, called ‘Volume_Mute’,
‘Treble_Buzzer_Hosp_app’ and ‘Bass_panorama’.
The ‘Volume_Mute’ line controls the sound level output of the
audio amplifier or to mute it in case of no video identification or
from user command. This line also controls the volume level
during set switch ‘on’ and ‘off’ (to prevent audio plop).
The ‘Treble’ and ‘Bass’ lines have another functionality:
– The ‘Bass_panorama’ line is used to switch the panorama
mode in widescreen sets (to fit 4:3 pictures into a 16:9
display, it is possible to apply a panoramic horizontal
distortion, to make a screen-fitting picture without black
sidebars or lost video).
– The ‘Treble_Buzzer_Hosp_app’ is used in ITV applications
for other feautures, and in widescreen sets to enable the
‘Tilt’ feature (via R3172 on diagram A8) in the deflection
part.
Control
Signal
Processing
User Interface
There are two control signals, called ‘KEYBOARD_protn’ and
‘IR’. Users can interact either through the Remote Control
transmitter, or by activation of the appropriate keyboard
buttons.
The L01 uses a remote control with RC5 protocol. The
incoming signal is connected to pin 67 of the UOC.
The 'Top Control' keyboard, connected to UOC pin 80, can also
control the set. Button recognition is done via a voltage divider.
The ‘KEYBOARD_protn’ line, also serves to detect faults in the
E/W circuit, which would require the µP to shut down the set (by
forcing the power supply in standby mode).
Over Temperature protection
When the junction temperature exceeds the thermal shutdown
temperature (typ. 140º C), the IC will disable the driver. When
the VCC voltage drops to UVLO, the VCC capacitor will be
recharged to the V(start) level. If the temperature is still too high,
the VCC voltage will drop again to the UVLO level (Safe-Restart
mode). This mode will persist until the junction temperature
drops 8 degrees typically below the shutdown temperature.
9.7
I2C-Bus
The main control system, which consists of the microprocessor
part of the UOC (7200), is linked to the external devices (tuner,
NVM, MSP, etc) by means of the I2C-bus. An internal I2C-bus
is used to control other signal processing functions, like video
processing, sound IF, vision IF, synchronisation, etc.
LEB time
The LEB (Leading Edge Blanking) time is an internally fixed
delay, preventing false triggering of the comparator due to
current spikes. This delay determines the minimum ‘on’ time of
the controller.
Mains dependent operation enabling level
To prevent the supply from starting at a low input voltage, which
could cause audible noise, a mains detection is implemented
(Mlevel). This detection is provided via pin 8, that detects the
minimum start-up voltage between 60 and 100 V. As previous
mentioned, the controller is enabled between 60 and 100 V.
An additional advantage of this function is the protection
against a disconnected buffer capacitor (CIN). In this case, the
supply will not be able to start-up because the VCC capacitor
will not be charged to the start-up voltage.

For the control of the input and output selections, there are
three lines:

microprocessor on whether a video signal is available on
the SCART1 AV input and output port.
– 0 to 2 V: INTERNAL 4:3
– 4.5 to 7 V: EXTERNAL 16:9
– 9.5 to 12 V: EXTERNAL 4:3
• STATUS2 This signal provides information to the
microprocessor on whether a video signal is available on
the SCART2 AV input and output port (signal is low). For
sets with an SVHS input, it provides the additional
information if a Y/C or CVBS source is present (signal is
high). The presence of an external Y/C source makes this
line ‘high’ while a CVBS source makes the line ‘low’.

Tuner IF
Pin 3 of the UOC (SEL-IF-LL’_M-TRAP), is an output pin to
switch the SAW-filter to the appropriate system.
• If UOC pin 3 is ‘low’, the selected system is:
– West Europe: PAL B/G, I, SECAM L/L’
– East Europe: PAL B/G
– Asia Pacific: NTSC M
• If UOC pin 3 is ‘high’, the selected system is:
– West Europe: SECAM L’, L’-NICAM
– East Europe: PAL D/K
– Asia Pacific: PAL B/G, D/K, I
Note: For West Europe, two separate SAW filters (1002 and
1004) are used for video and audio (Quasi Split Sound
demodulation). For East Europe, one SAW filter (1003) is used
for both (Intercarrier demodulation).
9.7.8
Protection Events
Several protection events are controlled by the UOC:
• BC protection, to protect the picture tube from a too high
beam current. The UOC has the capability of measuring
the normal back level current during the vertical flyback. So
if for some reason the CRT circuit is malfunctioning (i.e.
high beam current), the normal black current will be out of
the 75 µA range, and the UOC will trigger the power supply
to shut down. However, this is a high beam-current
situation, the TV screen will be bright white before the set
is shut down.
• I2C protection, to check whether all I2C IC's are
functioning.
In case one of these protections is activated, the set will go into
‘standby’. The ‘on’ and ‘standby’ LEDs are controlled via the
UOC.

Power Supply Control
The microprocessor part is supplied with 3.3 V and 3.9 V both
derived from the ‘MainAux’ voltage via a 3V3 stabiliser (7560)
and a diode.
Two signals are used to control the power supply:
• Stdby_con This signal is generated by the microprocessor
when over-current takes place at the ‘MainAux’ line. This is
done to enable the power supply into standby burst mode,
and to enable this mode during a protection. This signal is
‘low’ under normal operation conditions and goes to ‘high’
(3.3 V) under ‘standby’ and ‘fault’ conditions.
• POWER_DOWN This signal is generated by the power
supply. Under normal operating conditions this signal is
‘high’ (3.3 V). During ‘standby’ mode, this signal is a pulse
train of approx. 10 Hz and a ‘high’ duration of 5 ms. It is
used to give information to the UOC about the fault
condition in the Audio amplifier supply circuit. This
information is generated by sensing the current on the
‘MainAux’ line (using voltage drop across R3564 to trigger
TS7562). This signal goes ‘low’ when the DC-current on
the ‘MainAux’ line exceeds 1.6 - 2.0 A. It is also used to
give an early warning to the UOC about a power failure.
Then the information is used to mute the sound amplifier to
prevent a switch off noise and to solve the switch-off spot.
