Safety Instructions, Warnings, and Notes
2. Safety Instructions, Warnings, and Notes
2.1

Safety Instructions
Safety regulations require that during a repair:
• Connect the set to the Mains (AC Power) via an isolation
transformer (> 800 VA).
• Replace safety components, indicated by the symbol h,
only by components identical to the original ones. Any
other component substitution (other than original type) may
increase risk of fire or electrical shock hazard.
Safety regulations require that after a repair, the set must be
returned in its original condition. Pay in particular attention to
the following points:
• Route the wire trees correctly and fix them with the
mounted cable clamps.
• Check the insulation of the Mains (AC Power) lead for
external damage.
• Check the strain relief of the Mains (AC Power) cord for
proper function.
• Check the electrical DC resistance between the Mains (AC
Power) plug and the secondary side (only for sets which
have a Mains (AC Power) isolated power supply):
1. Unplug the Mains (AC Power) cord and connect a wire
between the two pins of the Mains (AC Power) plug.
2. Set the Mains (AC Power) switch to the "on" position
(keep the Mains (AC Power) cord unplugged!).
3. Measure the resistance value between the pins of the
Mains (AC Power) plug and the metal shielding of the
tuner or the aerial connection on the set. The reading
should be between 4.5 Mohm and 12 Mohm.
4. Switch "off" the set, and remove the wire between the
two pins of the Mains (AC Power) plug.
• Check the cabinet for defects, to avoid touching of any
inner parts by the customer.

– 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. We do not recommend adjusting this unit during
repair.
Be careful during measurements in the high voltage
section and on the picture tube.
Never replace modules or other components while the unit
is '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.
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 V_dc). 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 standby (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
semiconductors in the unit, irrespective of the type
indication on these semiconductors.

All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD, w). Careless handling
during repair can reduce life drastically. Make sure that,
during repair, 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:

•
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 Electrical
Replacement Parts List. Therefore, always check this list
when there is any doubt.

2.3.3
Rework on BGA (Ball Grid Array) ICs
•
General
Although (LF)BGA assembly yields are very high, there may
still be a requirement for component rework. By rework, we
mean the process of removing the component from the PWB
and replacing it with a new component. If an (LF)BGA is
removed from a PWB, the solder balls of the component are
deformed drastically so the removed (LF)BGA has to be
discarded.
Device Removal
As is the case with any component that, it is essential when
removing an (LF)BGA, the board, tracks, solder lands, or
surrounding components are not damaged. To remove an
(LF)BGA, the board must be uniformly heated to a temperature
close to the reflow soldering temperature. A uniform
temperature reduces the chance of warping the PWB.
To do this, we recommend that the board is heated until it is
certain that all the joints are molten. Then carefully pull the
component off the board with a vacuum nozzle. For the
appropriate temperature profiles, see the IC data sheet.
Area Preparation
When the component has been removed, the vacant IC area
must be cleaned before replacing the (LF)BGA.
Removing an IC often leaves varying amounts of solder on the
mounting lands. This excessive solder can be removed with
either a solder sucker or solder wick. The remaining flux can be
removed with a brush and cleaning agent.
After the board is properly cleaned and inspected, apply flux on
the solder lands and on the connection balls of the (LF)BGA.
Note: Do not apply solder paste, as this has shown to result in
problems during re-soldering.
Device Replacement
The last step in the repair process is to solder the new
component on the board. Ideally, the (LF)BGA should be
aligned under a microscope or magnifying glass. If this is not
possible, try to align the (LF)BGA with any board markers.
To reflow the solder, apply a temperature profile according to
the IC data sheet. So as not to damage neighbouring
components, it may be necessary to reduce some
temperatures and times.

2.3.4
Lead Free Solder
Some PWBs in this chassis are “lead-free prepared”. This is
indicated on the PWB by the PHILIPS lead-free logo (either by
a service-printing or by a sticker). It does not mean that leadfree solder is actually used!
P
b
Figure 2-3 Lead-free logo
Due to this fact, 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.
Use only adequate solder tools applicable for lead-free
soldering tin.
Adjust your solder tool so that a temperature around 217 220 deg. C is reached at the solder joint.
Do not mix lead-free soldering tin with leaded soldering tin;
this will lead to unreliable solder joints!
Use only original spare parts listed in this manual. These
are lead-free parts!
On the website www.atyourservice.ce.philips.com (needs
subscription, not available for all regions) you can find
more information on:
– Aspects of lead-free technology.
– BGA (de-)soldering, heating-profiles of BGAs used in
Philips sets, and others.
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 - 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.

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.
Snowy picture
Check CSM line 6. If this line reads “Not Tuned”, check the
following:
• Antenna not connected. Connect the antenna.
• No antenna signal or bad antenna signal. Connect a proper
antenna signal.
• The tuner is faulty (in this case line 2, the Error Buffer line,
will contain error number 10). Check the tuner and replace/
repair the tuner if necessary.
5.4.2

• The picture improves after you have pressed the AUTO
PICTURE button on the remote control transmitter,
Then:
1. Press the AUTO PICTURE button on the remote control
transmitter repeatedly (if necessary) to choose
PERSONAL picture mode.
2. Press the MENU button on the remote control transmitter.
This brings up the normal user menu.
3. In the normal user menu, use the MENU UP/DOWN keys
to highlight the PICTURE sub menu.
4. Press the MENU LEFT/RIGHT keys to enter the PICTURE

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.
For this chassis, the ComPair interface box and the TV
communicate via a bi-directional service cable via the service
connector.
The ComPair faultfinding program is able to determine the
problem of the defective television. ComPair can gather
diagnostic information in two ways:
• 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
EN 12
5.
Service Modes, Error Codes, and Fault Finding
L04HU AA
television is working correctly and only to a certain extends.
When this is not the case, ComPair will guide you through
the faultfinding tree by asking you questions (e.g. Does the
screen give 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.
Note: If you encounter any problems, contact your local
support desk.
5.5
The error code buffer contains all errors detected 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 displayed at the left side and all other errors shift one
position to the right.
5.5.1
Beside fault finding, ComPair provides some additional
features like:
• Up- or downloading of pre-sets.
• Managing of pre-set lists.
• Emulation of the 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 Mono-carrier.
– 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.

• AC Adapter: T405-ND.
• ComPair Quick Start Guide: ST4190.
How To Read The Error Buffer
You can read the error buffer in 3 ways:
• On screen via the SAM (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 detected first and
error code 9 is the last detected (newest) error
• Via the blinking LED procedure (when you have no
picture). See “The Blinking LED Procedure”.
• Via ComPair.
5.5.2
How To Clear The Error Buffer
The error code buffer is cleared in the following cases:
• By using the CLEAR command in the SAM menu:
– To enter SAM, press the following key sequence on the
remote control transmitter: “062596” directly followed
by the OSD/STATUS button (do not allow the display
to time out between entries while keying the
sequence).
– Make sure the menu item CLEAR is highlighted. Use
the MENU UP/DOWN buttons, if necessary.
– Press the MENU RIGHT button to clear the error
buffer. The text on the right side of the “CLEAR” line will
change from “CLEAR?” to “CLEARED”
• If the contents of the error buffer have not changed for 50
hours, the error buffer resets automatically.
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 adapter to the supply connector
(marked with “POWER 9V DC”) of the ComPair interface.
4. Switch the ComPair interface “OFF”.
5. Switch the television set “OFF” with the mains switch.
6. Connect the ComPair interface cable between the
connector on the rear side of the ComPair interface
(marked with “I2C”) and the ComPair connector at the rear
side of the TV.
7. Plug the mains adapter in a mains outlet, and switch the
interface “ON”. 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.
Error Codes
Note: If you exit SAM by disconnecting the AC power from the
television set, the error buffer is not reset.
5.5.3
Error Codes
In case of non-intermittent faults, write down the errors present
in the error buffer and clear the error buffer before you begin
the repair. This ensures 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
and not the actual cause of the problem (for example, a fault in
the protection detection circuitry can also lead to a protection).

The Blinking LED Procedure
-
-
When the SDM is entered, the front LED will blink the contents
of the error-buffer:
• When all the error-codes are displayed, the sequence
finishes with a LED blink of 1.5 seconds,
• The sequence starts again.
Example of error buffer: 12 9 6 0 0
After entering SDM, the following occurs:
• 1 long blink of 5 seconds to start the sequence,
• 12 short blinks followed by a pause of 1.5 seconds,
• 9 short blinks followed by a pause of 1.5 seconds,
• 6 short blinks followed by a pause of 1.5 seconds,
• 1 long blink of 1.5 seconds to finish the sequence,
• The sequence starts again at 12 short blinks.
Protections
If a fault situation is detected, an error code will be generated;
and, if necessary, the television set will go into 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 protection mode. The error codes of the
error buffer and the blinking LED procedure can be read via the
Service Default Menu (SDM), or via ComPair.
To get a quick diagnosis the chassis has three service modes
implemented:
• The Customer Service Mode (CSM).
• The Service Default Mode (SDM).
• The Service Alignment Mode (SAM).

NVM Editor
In some cases, it can be handy if one directly can change the
NVM contents. This can be done with the “NVM Editor” in SAM
mode.
Using 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.

3. If it is “1”, then check the data of the NVM addresses as in
the next table. If the data is not correct, then set these
addresses to diagram values.
4. If it still not works, track Scavem output from pin64 of
HERCULES to CRT panel.

Figure 5-12 Fault finding tree “No sound”
No RF audio for QSS/Inter-Carrier stereo sets.
1. Check pin 99 and 100 for SIF signal (for QSS) or pin 104
and 105 for video with SIF (for Inter-Carrier)
2. If signal is not present, check for the QSS/FMI bit settings.
Check also the NVM data.
3. If signals are present and still no audio, check the audio
supply voltage +8V are present.
4. If still no audio signal at Hercules output, Hercules is faulty.
No AV audio.
1. Check troubleshooting methods in section “Source
Selection”.
2. Check the output of the Hercules to see if there is signal
available. If no, check the normal operating condition and
also the NVM data.
3. If still no audio signal at Hercules output, Hercules is faulty.
Note: If there is audio signal at Hercules output and no audio
at loudspeaker, proceed to Audio Amplifier troubleshooting
methods.
5.8.9
Audio Amplifier
No RF as well as AV audio at the loudspeaker:
1. Check that the normal operation condition of the amplifier
is met.
2. If normal operation conditions are met, check the continuity
from Hercules output to input of the amplifier.
3. If continuity is there and still no audio, check speaker wire
connections. If still no audio, amplifier IC might be faulty

Note:
• The Service Default and Alignment Mode (SDAM) is
described in chapter 5 “Service Modes, ...”.
• Menu navigation is done with the CURSOR UP, DOWN,
LEFT, or RIGHT keys of the remote control transmitter.

General Alignment Conditions
11.
Perform all electrical adjustments under the following
conditions:
• AC voltage and frequency: 120 V_ac / 60 Hz or 240 V_ac /
50 Hz (region dependent).
• Connect the set to the AC power (a.k.a. Mains voltage) via
an isolation transformer with a low internal resistance.
• 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 /

screen on CRT without any OSD info) with a signal
strength of 1 V_pp.
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 figure “V_cutoff waveform”). 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 V_dc value for the
alignment. Adjust the V_cutoff of this gun with the
SCREEN potentiometer (see figure “Top view family
board”) on the LOT to 160 V_dc, except for the 25/28BLD
picture tube (Black Line Display, for EU only); this tube
must be aligned to 140 V_dc.
Restore BRIGHTNESS and CONTRAST to normal (= 31).

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 and switching the set off with
the standby button on the remote saves the changes in the
Option Byte settings. Some changes will only take effect after
the set has been switched OFF and ON with the AC power
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 Bytes per typenumber.

The tuning system features 181 channels with on-screen
display. The main tuning system uses a tuner, a
microcomputer, and a memory IC mounted on the main panel.
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 favorite stations, customer-preferred settings,
and service / factory data.
The on-screen graphics and closed caption decoding are done
within the microprocessor where they are added to the main
signal.
Notes:
• Only new circuits compared to the M8 (L01.1 for other
regions) chassis are described in this chapter. For the
other circuit descriptions, see the manual of the M8 (L01.1)
chassis.
• Figures can deviate slightly from the actual situation, due
to different set executions.
• For a good understanding of the following circuit
descriptions, please use the diagrams in sections “Block
Diagrams, ...”, and/or “Electrical Diagrams”. Where
necessary, you will find a separate drawing for clarification.
9.1
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.
Introduction
The "L04" chassis is a global TV chassis for the model year
2004 and is used for TV sets with large screen sizes (from 21
to 36 inch), in Super Flat and Real Flat executions (both in 4:3
and 16:9 variants).
There are three types of CRT namely the 100 degrees, 110
degrees and Wide Screen CRT.
• The 100 deg. 4:3 CRT is raster-correction-free and does
not need East/West Correction (except when used in AP
regions), therefore the corrections needed are Horizontal
Shift, Vertical Slope, Vertical Amplitude, Vertical SCorrection, Vertical Shift, and Vertical Zoom for geometry
corrections.
• The 110 deg. 4:3 CRT comes with East/West Correction.
In addition to the parameter mentioned above, it also
needs the Horizontal Parallelogram, Horizontal Bow,
Horizontal Shift, East/West Width, East/West Parabola,
East/West Upper and Lower Corners, and East/West
Trapezium correction.
• The Wide Screen TV sets have all the correction of the 110
deg. 4:3 CRTs and also have additional picture format like
the 4:3 format, 16:9, 14:9, 16:9 zoom, subtitle zoom, and
the Super-Wide picture format.
In comparison to its predecessor (the M8/L01.1), this chassis is
has the following (new) features:
• Audio: The sound processor is part of the UOC processor
(called “Hercules”).
• Video: Enhanced video features, video drivers, and Active
Control.
• Control: Comparable to M8/L01.1 (e.g. Dual clock, I/O
mapping, I/O switching).
• Power Supply: Adapted to supply the Hercules IC, and to
enable 0.5 W Standby power dissipation. Also provisions
are made for future extensions like DVD and iDTV.
The standard architecture consists of a Main panel (called
"family board"), a Picture Tube panel, a Side I/O panel, and a
Top Control panel. The Main panel consists primarily of
conventional components with some surface mounted devices
in the audio and video processing part.
The functions for video/audio processing, microprocessor (P),
and CC/Teletext (TXT) decoder are all combined in one IC
(TDA1200x, item 7200), the so-called third generation Ultimate
One Chip (UOC-III) or “Hercules”. This chip is mounted on the
“solder” side of the main panel, and has the following features:
Control, small signal, mono/stereo, and extensive Audio/
Video switching in one IC.
Upgrade with digital sound & video processing.
Alignment free IF, including SECAM-L/L1 and AM.
FM sound 4.5/5.5/6.0/6.5, no traps/bandpass filters.
Full multi-standard color decoder.
One Xtal reference for all functions (microprocessor, RCP,
TXT/CC, RDS, color decoder, and stereo sound
processor).

Startup Sequence
When the set is connected to the AC power, the rectified line
voltage (via winding 4-5 of L5531 connected to pin 14 of
IC7531) will start the internal voltage source to charge the V_cc
capacitor (C2532). The IC starts to switch as soon as the V_cc
reaches the V_cc start level of 9.5 V. This supply is
automatically taken over by winding 1-2, as soon as the V_cc
is high enough, and the internal supply source will stop (for high
efficiency switching).

V_cc
This pin is connected to the supply voltage. An internal current
charges the V_cc capacitor (2532), and the start-up sequence
is initiated when this voltage reaches a level of 9.5 V. Note: The
output power is disabled when the voltage gets below 9 V
(UVLO). Operating range is between 0 to 40 V.

RC
Frequency setting
6
REG
This pin is connected to the feedback loop. The pin contains two
functions: 1) Between 1 to 1.425 V it controls the "on" time. 2)
Above the threshold of 3.5 V, it is possible to initiate "burst
mode" standby.
11
Demag
Before the Hercules (IC7200) can generate horizontal drive
pulses, the +3.3V supply voltages must be present. After the
start up command of the microprocessor (via I2C), the
Hercules outputs the horizontal pulses. These horizontal
pulses begin “initially” with double line frequency and then
change “gradually” to line frequency in order to limit the current
in the line stage (slow-start).
The VDRA and VDRB signals are the balanced output currents
(sawtooth shaped) of the frame oscillator (pins 106 and 107 of
the Hercules). These output signals are balanced, so they are
less sensitive to disturbances.
This pin is connected to the V_cc winding of 5531. It has three
functions: 1) During Magnetisation, the input voltage is sensed
to compensate OCP level for OPP. 2) During demagnetisation,
the output voltage is sensed for OVP and 3) A comparator is
used to prevent continuous conduction when output is
overloaded.
12
Sense
This pin contains three different functions.: 1) Dectection of soft
start, protection levels of 2) OCP, and 3) SWP.
14
Drain
This pin is connected to the drain of the switch or center tap of
the transformer. It contains three functions: 1) M-level (mainsdependent operation-enabling level), 2) Supply for start-up
current, and 3) Valley detection.
There is a current source inside the UOC at pin 102. This
pumps energy in the capacitor connected to this pin producing
a pure saw tooth. The vertical drive signals and the E/W
correction signal are derived.
Pin 108 is the East-West drive (or AVL), and it is a single ended
current output. The correction for “horizontal width for changed
EHT” from this pin is available by setting the HCO bit to “1”.
As C2532 of IC7531 is charged, it will also start to charge the
V_cc capacitor (C2511) of IC7511. Via resistor R3519 and
C2511, the TEA1506 starts to switch as soon as the V_cc
voltage reaches the V_cc start level of is about 11 V. The V_cc
voltage is automatically taken over by the main transformer
L5512 (winding 2-3) when the V_cc is high enough (when this
voltage is even higher than the voltage on C2511, there is no
current flow from C2532 to C2511 due to diode D6512).
The Phase-2 Compensation available at pin 113 gives frame
correction for high beam currents. The phase compensation
signal is used to correct the phase of the picture from the
horizontal drive signal.
Pin 63 is the SANDCASTLE output (contains all sync info) and
also HORIZONTAL FLYBACK (HFB) input.
Pin 97 is the EHT tracking/over-voltage protection pin. The
HCO bit can switch on the tracking on EW. If the voltage at pin
97 exceeds 3.9 V, the over-voltage protection will be activated
and the horizontal drive is switched “off” via a slow stop.

the output is overloaded.

9.3.2
Horizontal Deflection
There are several executions (depending on the CRT):
• Sets with no East-West correction. The principle of the
horizontal deflection is based on the quasi-diode
modulation circuit. This horizontal deflection circuit
supplies the deflection current and auxiliary voltages from
the LOT.
• Sets with East-West correction. The principle of the
horizontal deflection is based on a diode modulator with
east-west correction. This horizontal deflection circuit
supplies the deflection current and auxiliary voltages from
the LOT.
• Sets with dynamic East-West correction. The principle
of the horizontal deflection is based on a diode modulator
with dynamic east-west correction for picture tubes with
inner pincushion. This horizontal deflection circuit supplies
the deflection current and auxiliary voltages from the LOT.
Standby Mode
In this mode, IC7511 (TEA1506) will be totally disabled. So
there is no voltage on the main transformer output. But IC7531
(TEA1523) will still work and will provide the necessary output
voltages (6V -> 5V, 3.3V, 3V -> 1.8V) to the Hercules (IC7200).
Basic Principle
During a scan period, either the Line Transistor or diode(s)
conduct to ensure a constant voltage over the deflection coil
(that results in a linear current). During the flyback period, the
Line Transistor stops conducting, and the flyback capacitor(s)
together with the inductance of the deflection coil creates
oscillation.

First Part of Scan
Pin 62 of the UOC delivers the horizontal drive signal for the
Line Output stage. This signal is a square pulse of line
frequency. L5402 is the flyback drive transformer. This
transformer de-couples the line output stage from the UOC. It
has a direct polarization. The flyback drive circuit works with
the start-up supply taken from +6V of the Aux supply (and
subsequently taking from VlotAux+9V). When the H-drive is
high, TS7404 conducts, and transformer L5402 starts to store
energy. The base of the line transistor TS7405 is low and
therefore blocks. The current in the deflection coil returns from
diode D6404.
frequency) taken from the line aux output. Then a series of
width-modulated pulses is formed via two inverted phase
amplifiers, filtered by an inductor, which then directly drive the
diode modulated line circuit.
Second Part of Scan
When the H-drive is low, TS7404 does not conduct, and the
energy that is stored in the transformer will transfer to the
secondary, making the base of the Line Transistor high. Then
the Line Transistor starts to conduct. The current in the
deflection coil returns from the transistor in another direction.
Upon entering the picture geometry menu in the SAM mode,
the following corrections will be displayed.
• EWW: East West Width.
• EWP: East West Parabola.
• UCP: Upper Corner Parabola.
• LCP: Lower Corner Parabola.
• EWT: East West Trapezium.
The East-West drive circuit realizes them all. The settings can
be changed by a remote control. All changed data will be
stored into the NVM after the geometry alignment.
East-West Correction
To achieve a good geometry, dynamic S-correction is needed.
The design is such that the tube/yoke needs East-West
correction. Besides that, an inner pincushion is present after
East-West correction. The line deflection is modulated with a
parabolic voltage (frame frequency). In this way it is not so
much at top and bottom, and much more in the middle.
Flyback
At the moment the H-drive becomes high, the base of the Line
Transistor becomes low. Both the Line Transistor and the
Flyback Diode will block. There is an oscillation between the
flyback capacitor C2412 and the deflection coil. Because of the
inductance of the LOT, the Line Transistor cannot stop
conducting immediately. After the Line Transistor is out of
conduction, the flyback pulse is created. The flyback capacitor
charges until the current in the deflection coil reduce to zero.
Then it discharges through the deflection coil and the deflection
current increases from the other direction. The flyback diode
conducts and is back to the first part of the scan.
Panorama
For Wide Screen sets, the S-correction of the picture has to
adapt between the different picture modes. In particular,
between 16:9 Wide Screen and 4:3 picture modes. This is
achieved with the (separate) Panorama circuit (see diagram
“G”). A signal (I2SDI1) from the UOC controls the state of
TS7463. When in the normal 16:9 Wide Screen mode, the
signal is “low” and therefore TS7463 is switched “off”.
When the 4:3 mode is selected, this signal from the UOC is
pulled “high”, switching TS7463 “on”. The relay 1463 on the
Panorama panel is subsequently turned “on” and, in effect,
paralleling capacitor C2475/C2474 to the S-Cap C2469/
C2470. This changes the overall effective S-correction. The
relay is switched “on” in 4:3 and Superwide picture modes.
Linearity Correction
Because the deflection coil has a certain resistance, a picture
without any linearity issues cannot be expected. L5401 is the
linearity coil to compensate for this resistance. It is a coil with a
pre-magnetized core. This correction is called linearity
correction.
9.3.3
Horizontal S-Correction
Because the electronic beam needs to travel a longer distance
to both sides of the screen than the center, the middle of the
screen would become narrower than both sides. To prevent
this, a parabolic voltage is applied across the deflection coil
during scan. To create this parabolic voltage, a capacitor called
S-cap (C2417/C2418) is used as a voltage source during scan.
The sawtooth current of the deflection through this capacitor
creates the required parabolic voltage. This correction is called
S-Correction.
The horizontal deflection provides various auxiliary voltages
derived either directly or indirectly from the secondary pins of
the LOT:
• +9V: This supplies the Hercules’s flyback driver.
• +11V: This supplies the frame amplifier.
• -12V: This supplies the frame amplifier.
• 50V: This supplies the frame amplifier.
• Filament: This supplies the heater pins of the picture tube.
• VideoSupply (+200V from primary side of LOT): This
supplies the RGB amplifier and Scavem circuit at the CRT
panel.
Mannheim-Circuit
When the EHT is heavily loaded with a bright line, the flyback
time can be increased a bit in this situation. As a result, the
scan delays a bit causing a DC-shift to the right in the next line,
which would create a small spike on the S-cap. This spike
oscillates with the inductance of the deflection coil and the
primary of LOT. The result is visible in vertical lines under
horizontal white line. This is called the Mannheim-effect.
To prevent this from happening, a circuit called Mannheimcircuit is added. This consists of C2415, R3404, R3417 and
D6406. During the scan, C2415 is charged via R3417. During
the flyback, the S-correction parabola across the S-Cap
C2417/C2418 is in its most negative, and D6406 conducts.
Thus, C2415 is switched in parallel to C2417/C2418 during
flyback. As C2415 is much larger than C2417/C2418, the
voltage across C2415 reduces the Mannheim-effect oscillation.
Class D East-West Driver
To reduce the power loss of the normal used linear East-West
amplifier, a class-D East-West circuit is used. To achieve this,
the East-West parabola waveform EW_DRIVE from the
Hercules (frame frequency) is sampled with a saw tooth (line
Auxiliary Voltages
Notes:
• The V_T voltage (to tuner) is drawn from V_batt.
• The EHT voltage is generated by the Line Output
Transformer (LOT). The Focus and Vg2 voltages are
created with two potentiometers integrated in the
transformer.
9.3.4
Beam Current
The beam current is adjusted with R3451 and R3452. The
components R3473, R3453 and C2451 determine the
EHT_info characteristic. The voltage across C2412 varies
when the beam current changes. This EHT_info is used to
compensate the picture geometry via pin 97 of the Hercules
when the picture changes rapidly, and compensate the phase
2 loop via pin 113 of the Hercules. Also from the EHT_info line,
a BCL signal is derived and sent to the Hercules for controlling
the picture’s contrast and brightness.
When the picture content becomes brighter, it will introduce:
EN 70

L04HU AA
Circuit Descriptions, List of Abbreviations, and IC Data Sheets
•
Geometry distortion due to the impedance of the LOT
causing the EHT to drop.
• Picture blooming due to the picture characteristics
Because of the above mentioned, we will need a circuit for
Beam Current Limiter (BCL) and EHT compensation
(EHT_info). These two circuits derive the signal from the
picture tube current info through LOT pin 10.
across R3482 will tend to increase as well, while the voltage
across D6481 is fixed. Up to certain level (triggering point),
TS7481 will be “on” and will force the EHT_info > 3.9 V. The
chassis will be shut down through a soft stop sequence.
9.3.7
The Frame stage consists fully of discrete components. This
has the advantage for better flash behavior than when an IC
was used.
BCL
• When the BCL pin voltage goes to 2.8 V, the Hercules will
start to limit CONTRAST gain.
• When it reaches 1.7 V, then the BRIGHTNESS gain limit
will start to react.
• When BCL pin voltage goes to 0.8 V, the RGB will be
blanked.
The Frame differential drive signal from the Hercules comes
from a current source. Resistors R3460 and R3461 convert
them into a voltage, and feed them into the differential amplifier
TS7455 and TS7456. The output of TS7456 is input to the next
amplification stage of TS7452. Finally, TS7451 and TS7453
deliver the Vertical yoke current to the coil and feedback
through the sensing resistors R3471 and R3472.
D6458 and TS7454 are used to bias TS7451 and TS7453, to
get rid of zero crossovers, which can cause horizontal lines at
the screen center.
The negative supply is from -12V and the positive scanning
supply is from +12V through D6459. The flyback supply is
derived from D6455, D6456 and C2456. This circuit is a voltage
doubler, which stores energy in C2456 during the Line flyback
period and delivers the energy to C2465 during the Line
scanning period. Throughout the Frame period, the charging
and discharging of C2456 works alternatively. However, at the
first half of the Frame scanning, TS7451 is “on” and consumes
all the charge from C2456. When entering 2nd half Frame
period, TS7451 is “off”, so C2456 will gradually charge up to the
required flyback supply.
Components TS7483, R3490, R3491, R3492, and C2483 are
for fast beam current limiting (e.g. with a Black-to-White
pattern).
Components R3454, D6451, D6450, C2453, R3493, and
C2230 are for average beam current limiting. C2453 and
R3493 also control the timing where average beam current
limiting is more active or less active.
EHT_info
The “PHI2 correction” is to correct the storage time deviation of
the Line Output Transistor, which is causing geometry
distortion due to brightness change.
Line EHT_info is to correct the geometry distortion due to EHT
deviation.
Both of them feedback through the EHTO and PH2LF pin, and
correct the geometry through the East-West circuit.
Power Down
The power down connection is for EHT discharge during AC
Power “Off” state. In the Hercules, if EHT_info > 3.9 V, it will
trigger the X-ray protection circuit via a 2fH soft stop sequence.
The Hercules bits OSO (Switch Off in Vertical Over scan) and
FBC (Fixed Beam Current Switch Off) will discharge the EHT
with 1mA cathode current at over-scan position.
During switch-off, the H_out frequency is doubled immediately
and the duty cycle is set to 25% fixed, during 43 ms. The RGB
outputs are driven “high” to get a controlled discharge of the
picture tube with 1 mA during 38 ms. This will decrease the
EHT to about half the nominal value (= safety requirement).
When bit OSO is set, the white spot/flash during switch-off will
be written in overscan and thus will not be visible on the screen.
Careful application must guarantee that the vertical deflection
stays operational until the end of the discharge period.
9.3.5
9.3.6
C2463, R3464 and D6457 are for boosting the base voltage of
TS7451 during the flyback period and the 1st half Frame period
as well. C2463 is charged by D6457 during the 2nd half
scanning. R3467 and R3468 are for oscillation damping.
The V_guard protection is to protect the Frame stage if a fault
condition happens. The V_guard will sense the pulse with
voltage > 3.8 V and period < 900 us. Any signal out of this
range will be considered as fault, and the chassis will be shut
down.
9.3.8
X-ray Protection
The X-ray protection circuit rectifies the filament voltage and
uses it to trigger TS7481 when the EHT is too high. TS7481 is
biased at “off” condition by D6480, R3482, and R3483 during
normal operation. When the EHT goes too high, the voltage
Tilt and Rotation
The rotation control signal is a PWM output from the UOC. It is
filtered by R3252, R3246, R3259 and C2259. The DC voltage
after filtering at C2259 will be amplified by R3245 (Main Board)
and R3390 (CRT panel).
The output stage functions similarly as in M8/L01.1 with
rotation IC TDA8941P. TS7331/TS7382 and TS7332/TS7381
will function alternatively corresponding to the rotation setting.
DAF
The Dynamic Astigmatic Focus (DAF) circuit is required by
34RF sets only. It provides vertical DAF and horizontal DAF.
Both of the parabola signals are derived through integration by
using chassis available signals:
• The vertical parabola is using RC integration (via R3403
and C2401) on the Frame sensing resistor saw tooth
(Frame_FB).
• The horizontal parabola is obtained by 2 RC integration
(R3409, R3410, C2402, C2403) on the +9V LOT output.
Both of the parabolas are added on the output stage through
adder TS7402 and TS7403. The collector of TS7402 emitterdrives TS7401 and is amplified by pull up resistor R3411.
D6401 and C2405 provide the rectified supply voltage.
Vertical Deflection
9.3.9
CRT panel
The RGB amplifier stage is exactly the same as in M8/L01.1.
However, the RGB amplifier IC has been changed to
TDA6107AJF or TDA6108AJF. The “A” indication is with gain
of “80” rather than “50” in M8/L01.1. The diode D6332 used in
the former chassis, to solve the bright screen during start up, is
not required because this IC has the error correction
implemented.
Scavem
In certain versions, the Scavem feature is used to enhance the
sharpness of the picture. The RGB signals are first
differentiated and subsequently amplified before feeding to an
auxiliary coil known as the SVM coil. The current, flowing
through the SVM coil during the picture intensity transients,
modulates the deflection field and thus the scan velocity.
Circuit Descriptions, List of Abbreviations, and IC Data Sheets
During the first half of the intensity increase, the scan velocity
is increased (thus decreasing the current density by spreading
it on a wider area). During the second half of the intensity
increase, the scan velocity is decreased (increasing the current
density by concentrating it on a smaller area). The increasing
current density transition is sharpened. A decreasing current
density transition is processed in a similar way and is also
sharpened.
In this chassis the SCAVEM signal is different from its
predecessor because the Hercules generates the differential
SCAVEM signal inside the IC.
The supply of the SCAVEM is taken from V_bat through a 1k5
/ 5 W resistor. Compared with the M8/L01.1, this has the
advantage of getting better performance for the pattern with
tremendous SCAVEM current (like V_sweep). In this former
chassis, because the supply was taken from the 200 V through
a 8k2 / 5 W resistor, the supply dropped significantly during a
large SCAVEM current. In this chassis, the drop due to the
pattern will be less because of the lower supply voltage
impedance.
In the Main Board, 1st stage amplification is taken care by 7208
with the pull up resistors (3361, 3387) located in the CRT panel.
TS7361 and TS7362 is the current buffer delivering the current
to the output stage. The diode D6361 is to lightly bias these
transistors, to get rid of the zero crossover of the stage.
After that, the signal is ac-coupled to TS7363 and TS7364
where the emitter resistors (R3364 and R3370) will determine
the final SCAVEM current. TS7363 and TS7364 are biased by
R3363, R3366, R3367 and R3368.
C2387, R3388, R3389, R3365, R3369, C2384, and C2385 are
used for suppressing unwanted oscillations.
The function of TS7376 is to limit the SCAVEM current from
going too high. It basically senses the voltage after R3373 and
clamps the SCAVEM signal through D6367 and C2376.

Control
The Micro Controller is integrated with the Video Processor,
and is called the Hercules. For dynamic data storage, such as
SMART PICTURE and SMART SOUND settings, an external
NVM IC is being used.

decoder with the possibility of different page storage depending
on the Hercules type number.
The Micro Controller ranges in ROM from 128 kB with no TXTdecoder to 128 kB with a 10 page Teletext or with Closed

Video source selection is done inside the Hercules. Therefore
it provides a video switch with 3 external CVBS inputs and a
CVBS output. All CVBS inputs can be used as Y-input for Y/C
signals. However, only 2 Y/C sources can be selected because
the circuit has 2 chroma inputs.
All input signals are converted to YUV, and looped through an
external interface. This to enable picture improvement features
(like LTI/CTI) or PIP.

The TDA9178 is an I2C-bus controlled IC (INCREDIBLE chip)
with YUV interface. This IC can do mainly histogram
processing, color transient improvement (CTI) and line
transient improvement (LTI).
• Luminance Vector Processing involves histogram function,
which provides scene dependent contrast improvement,
adaptive black and white point stretching.
• Color Vector Processing involves skin tone correction,
green enhancement and blue stretch.
• Spectral Processor involves step improvement processing,
contour processing, smart sharpness control, color
dependant sharpness and Color Transient Improvement.
• Noise detector, feature mode detector and cue flash
functions.

Audio Processing
The audio decoding is done entirely via the Hercules. The IF
output from the Tuner is fed directly to either the Video-IF or the
Sound-IF input depending on the type of concept chosen.
There are mainly two types of decoder in the Hercules, an
analog decoder that decodes only Mono, regardless of any
standards, and a digital decoder (or DEMDEC) that can decode
both Mono as well as Stereo, again regardless of any
standards.
In this chassis, the analog decoder is used in two cases:
• It is used for AM Sound demodulation in the Europe
SECAM LL’ transmission.
• It is used for all FM demodulation in AP AV-Stereo sets.
9.8.1
Diversity
The diversity for the Audio decoding can be broken up into two
main concepts:
• The Quasi Split Sound concept used in Europe and some
AP sets.
• The Inter Carrier concept, used in NAFTA and LATAM.
The UOC-III family makes no difference anymore between
QSS- and Intercarrier IF, nearly all types are softwareswitchable between the two SAW-filter constructions.
Simple data settings are required for the set to determine
whether it is using the Inter Carrier or the QSS concept. These
settings are done via the “QSS” and “FMI” bit found in SAM
mode. Due to the diversity involved, the data for the 2 bits are
being placed in the NVM location and it is required to write once
during startup.
On top of that, it can be further broken down into various
systems depending on the region. The systems or region
chosen, will in turn affect the type of sound standard that is/are
allowed to be decoded.
• For the case of Europe, the standard consists of BG/DK/I/
LL’ for a Multi-System set. There are also versions of
Eastern Europe and Western Europe set and the standard
for decoding will be BG/DK and I/DK respectively. FM
Radio is a feature diversity for the Europe sets. The same
version can have either FM Radio or not, independent of
9.
EN 75
the system (e.g. sets with BG/DK/I/LL’ can have or not
have FM radio).
For the case of NAFTA and LATAM, there is only one
transmission standard, which is the M standard. The
diversity then will be based on whether it has a dBx noise
reduction or a Non-dBx (no dBx noise reduction).
For the case of AP, the standard consists of BG/DK/I/M for
a Multi-System set. The diversity here will then depends on
the region. AP China can have a Multi-System and I/DK
version. For India, it might only be BG standard.

Audio Amplifier
The audio amplifier part is very straightforward. It uses the
integrated power amplifier TDA2616Q, and delivers a
maximum output of 2 x 10 W_rms.
The maximum operating condition for this amplifier is 21 V
unloaded. Normal operating supply is from 7.5 V to 16 V.
Muting is done via the VOLUME_MUTE line connected to pin
2 of the amplifier-IC and coming from the UOC.
