Service manual WP-795
1-3 ATSS sorting method
The TV set sweeps all the TV bands from beginning of VHF to end of UHF. The TV controlling software
for each program checks if a VPS CNI code is transmitted. If no VPS CNI code is found, the system check
if a CNI code is transmitted in the teletext lines ( Packet 8/30 format 1 ). If such a code ( VPS or teletext )
is found and if this code is in the ATSS list, the program is automatically named.
The programs found are then sorted in 4 groups :
Group I : It contains all the programs from the selected country and named by the TV controlling
software. Within this group the sorting order is fixed by the ATSS list.
Group II : It contains all the programs with a strong signal strength which are not listed in group I.
Group III : It contains all the programs with a weak signal strength which are not listed in group I.
Group IV : If two or more programs with the same code are found, only the strongest ( or if they have the
same level the one with the lowest frequency) is listed in group I, II or III. The others are listed in group
IV.
Note : If two programs with the same name but a different code are found these two programs are listed in
group I, II or III ( e.g. Regional program SW3 in Germany ).
The sorting order within group II, III, and IV is based on the channel frequency. The program with the
lowest frequency is allocated the first rank in its group, and so forth until the last program of the group
which has the highest frequency.

Service manual WP-795
Special case : France
If France is selected the TV controlling software sweeps the whole TV bands firstly with France system
selected ( positive video modulation) and secondly with Europe system selected ( negative video
modulation).
Special case : Switzerland
If Switzerland is selected the TV controlling software sweeps the whole TV bands firstly with Europe
system selected (negative video modulation) and secondly with France system selected ( positive video
modulation).
Special case : GB
Note for satellite receiver users : Before starting ATSS turn On your satellite receiver and tune “ SKY
NEWS “.
If GB is selected the TV controlling software seeks for programs only in UHF ( C21 to C70 ). The sorting
order is :
1 - BBC1
2 - BBC2
3 - ITV
4 - CH4
5 - CH5
6 - NEWS
If two or more “ identical “programs ( same name but different code e.g. BBC1 and BBC1 Scotland ) are
found the following programs in the list will be shifted up. (1 - BBC1, 2 - BBC1, 3 - BBC2, 4 - ITV, 5 CH4, 6 - CH5, 7 - NEWS, ..)
If one of the program above is not found, the associated program number remains empty ( freq.=467.25
Mhz - Skip selected - no name - system=GB).
example A : 1 - BBC1, 2 - BBC2, 3 - ITV, 4 - -----, 5 - CH5, 6 - NEWS, ...
example B ( if 2 BBC1 found ) : 1 - BBC1, 2 - BBC1, 3 - BBC2, 4 - ITV, 5 - -----, 6 - CH5, 7 - NEWS, ...

2 - Safety instruction
WARNING: Only competent service personnel may carry out work involving the testing or repair of this
equipment.
X-RAY RADIATION PRECAUTION
1.
Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid such
hazards, the high voltage must not exceed the specified limit. The nominal value of the high voltage of
this receiver is 26 KV at max beam current. The high voltage must not, under any circumstances, exceed
30KV. Each time a receiver requires servicing, the high voltage should be checked. It is important to use
an accurate and reliable high voltage meter.
2. The only source of X-RAY Radiation in this TV receiver is the picture tube. For continued X-RAY
RADIATION protection, the replacement tube must be exactly the same type tube as specified in the parts
list.
SAFETY PRECAUTION
1.
2.
3.
4.
5.
Potentials of high voltage are present when this receiver is operating. Operation of the receiver
outside the cabinet or with the back board removed involves a shock hazard from the receiver.
1) Servicing should not be attempted by anyone who is not thoroughly familiar with the
precautions necessary when working on high voltage equipment.
2) Discharge the high potential of the picture tube before handling the tube. The picture tube is
highly evacuated and if broken, glass fragments will be violently expelled.
If any Fuse in this TV receiver is blown, replace it with the FUSE specified in the Replacement Parts
List.
When replacing a high wattage resistor (oxide metal film resistor) in circuit board, keep the resistor
10 mm away from circuit board.
Keep wires away from high voltage or high temperature components.
This receiver must operate under AC 230 volts, 5O Hz. NEVER connect to DC supply or any other

PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this equipment have special safety-related characteristics. These
characteristics are often passed unnoticed by a visual inspection and the X-RAY RADIATION protection
afforded by them cannot necessarily be obtained by using replacement components rated for higher
voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in
this manual and its supplements, electrical components having such features are identified by designated
symbol on the parts list. Before replacing any of these components, read the parts list in this manual
carefully. The use of substitutes replacement parts which do not have the same safety characteristics as
specified in the parts list may create X-RAY Radiation.

Data Capture
The Data Capture section takes in the analogue Composite Vidéo and Blanking Signal (CVBS), and from
this extracts the required data, which is then decoded and stored in memory.
The extraction of the data is performed in the digital domain. The first stage is to convert the analogue
CVBS signal into a digital form. This is done using an ADC sampling at 12MHz. The data and clock
recovery is then performed by a Multi-Rate Video Input Processor (MuIVIP). From the recovered data
and clock the following data types are extracted WST Teletext (625/525), Closed Caption, VPS, WSS.
The extracted data is stored in either memory (DRAM) via the Memory Interface or in SFR locations.

Application Fields of the MSP 3415D
In the following sections, a brief overview about the two main TV sound standards, NICAM 728 and
German FM Stereo, demonstrates the complex requirements of a multistandard audio IC.
NICAM plus FM/AM-Mono
According to the British, Scandinavian, Spanish, and French TV-standards, high-quality stereo sound is
transmitted digitally. The systems allow two high-quality digital sound channels to be added to the
already existing FM/AM-channel. The sound coding follows the format of the so-called Near
Instantaneous Companding System (NICAM 728). Transmission is performed using Differential
Quadrature Phase Shift Keying (DQPSK. Table below offers an overview of the modulation parameters.
In the case of NICAM/FM (AM) mode, there are three different audio channels available: NICAM A,
NICAM B, and FM/AM-mono. NICAM A and B may belong either to a stereo or to a dual language
transmission. Information about operation mode and about the quality of the NICAM signal can be read
by the controlling software via the control bus. In the case of low quality (high bit error rate), the
controlling software may decide to switch to the analogue FM/AM-mono sound. Alternatively, an
automatic NICAM-FM/AM switching may be applied.
German 2-Carrier System (DUAL FM System)
Since September 1981, stereo and dual sound programs have been transmitted in Germany using the 2carrier system. Sound transmission consists of the already existing first sound carrier and a second sound
carrier additionally containing an identification signal. More details of this standard are given in Tables
below. For D/K very similar system is used.

FUNCTIONAL DESCRIPTION OF VIDEO PROCESSOR Vision IF amplifier
The vision IF amplifier can demodulate signals with positive and negative modulation. The PLL
demodulator is completely alignment-free.
The VCO of the PLL circuit is internal and the frequency is fixed to the required value by using the clock
frequency of the µ-Controller/Teletext decoder as a reference. The setting of the various frequencies is
made by the controlling software in subaddress 27H (38.9 MHz for all system except L’ or 33.9 MHz for
system L’). Because of the internal VCO the IF circuit has a high immunity to EMC interferences.
QSS Sound circuit
The sound IF amplifier is similar to the vision IF amplifier
and has an external AGC decoupling capacitor.
The single reference QSS mixer is realised by a multiplier. In this multiplier the SIF signal is converted to
the intercarrier frequency by mixing it with the regenerated picture carrier from the VCO. The mixer
output signal is supplied to the output via a high-pass filter for attenuation of the residual video signals.
With this system a high performance hi-fi stereo sound processing can be achieved.
Video switches
The video switch has one input for an external CVBS or Y/C signal. The selected CVBS signal can be
supplied to pin 38, the IF video output. The selection between both signals is realised by the controlling
software in subaddress 22H.
The video ident circuit is connected to the selected signal. This ident circuit is independent of the
synchronisation.
Synchronisation circuit
The IC contains separator circuits for the horizontal and vertical sync pulses and a data-slicing circuit
which extracts the digital teletext data from the analogue signal.
The horizontal drive signal is obtained from an internal VCO which is running at a frequency of 25 MHz.
This oscillator is stabilised to this frequency by using a 12 MHz signal coming from the reference
oscillator of the µ-Controller/Teletext decoder.
The horizontal drive is switched on and off via the soft start/stop procedure. This function is realised by
means of variation of the TON of the horizontal drive pulses.
The vertical synchronisation is realised by means of a divider circuit. The vertical ramp generator needs
an external resistor and capacitor. For the vertical drive a differential output current is available. The
outputs are DC coupled to the vertical output stage.

Appendix
Service manual WP-795
In the type TDA9367, intended for 90° picture tubes the following geometry parameters can be adjusted:
• Horizontal shift
• Vertical amplitude
• Vertical slope
• S-correction
• Vertical shift
The types which are intended to be used in combination with 110° picture tubes have an East-West
control circuit. The additional controls for these types are:
• EW width
• EW parabola width
• EW upper and lower corner parabola correction
• EW trapezium correction
• Vertical zoom, horizontal parallelogram and bow correction.
Chroma and luminance processing
The chroma band-pass and trap circuits (including the SECAM cloche filter) are realised by means of
gyrators and are tuned to the right frequency by comparing the tuning frequency with the reference
frequency of the colour decoder. The luminance delay line and the delay cells for the peaking circuit are
also realised with gyrators. The circuit contains a black stretcher function which corrects the black level
for incoming signals which have a difference between the black level and the blanking level.
Colour decoder
The ICs can decode PAL, NTSC and SECAM signals. The PAL/NTSC decoder does not need external
reference crystals but 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 µ-Controller/Teletext decoder.
The Automatic Colour Limiting (ACL) circuit (switchable via the ACL bit in subaddress 2OH) prevents
that oversaturation occurs when signals with a high chroma-to-burst ratio are received. The ACL circuit is
designed such that it only reduces the chroma signal and not the burst signal. This has the advantage that
the colour sensitivity is not affected by this function.
SOFTWARE CONTROL
The CPU communicates with the peripheral functions using Special function Registers (SFRS) which are
addressed as RAM locations. The registers for the Teletext decoder appear as normal SFRs in the µController memory map and are written to these functions by using a serial bus. This bus is controlled by
dedicated hardware which uses a simple handshake system for software synchronisation.
For compatibility reasons and possible re-use of software blocks, the TV processor is controlled by I2C
bus. The TV processor control registers cannot be read. Only the status registers can be read ( Read
address 8A ).
- 23 -
Appendix
Service manual WP-795
The SECAM decoder contains an auto-calibrating PLL demodulator which has two references, via the
divided 12 MHz reference frequency (obtained from the µ-Controller) which is used to tune the PLL to
the desired free-running frequency and the bandgap reference to obtain the correct absolute value of the
output signal. The VCO of the PLL is calibrated during each vertical blanking period, when the IC is in
search or SECAM mode.
The base-band delay line (TDA 4665 function) is integrated. This delay line is also active during NTSC
to obtain a good suppression of cross colour effects. The demodulated colour difference signals are
internally supplied to the delay line.
RGB output circuit and black-current stabilisation
In the RGB control circuit the signal is controlled on contrast, brightness and saturation. The ICs have a
linear input for external RGB signals. The signals for OSD and text are internally supplied to the control
circuit. The output signal has an amplitude of about 2 Volts black-to-white at nominal input signals and
nominal settings of the various controls.
To obtain an accurate biasing of the picture tube the 'Continuous Cathode Calibration’ system has been
included in these ICs. A black level off set can be made with respect to the level which is generated by
the black current stabilisation system. In this way different colour temperatures can be obtained for the
bright and the dark part of the picture.
The black current stabilisation system checks the output level of the 3 channels and indicates whether the
black level of the highest output is in a certain window or below or above this window. This indication is
read from the status byte 01 and is used for automatic adjustment of the Vg2 voltage during the production
of the TV receiver.
During switch-off of the TV receiver a fixed beam current is generated by the black current control circuit.
This current ensures that the picture tube capacitance is discharged. During the switch-off period the
vertical deflection is placed in an overscan position so that the discharge is not visible on the screen.

2-2 IF
The TDA936x has an alignment free IF PLL demodulator. The fully integrated oscillator is automatically
calibrated, using the 12 MHz crystal as a frequency reference. The IF frequency is simply set in TVProcessor by I2C bus.
The AFC information is available via I2C bus from the TV-Processor status bytes. The controlling
software uses this information for tuner frequency tracking ( automatic following ). The AFC windows is
typically 125Khz wide. The minimum frequency step of the tuner is 62.5 KHz.
This AFC function is disabled when a program is tuned using the direct frequency entry or after fine
tuning adjustment. Therefore it is recommended to tune channel with the TV search function ( manual or
ATSS ) or using the direct channel entry to enable the Automatic Frequency Control.

For SECAM L and L’ the TDA936x is switched to positive modulation via I2C bus. SECAM L’ only
occur in VHF band I and have their picture and sound carrier interchanged, compared to SECAM L and
PAL B/G channels. For SECAM L’ the picture carrier is situated at 33.9 MHz and the AM sound carrier
at 40.40 MHz. The IF PLL reference is tuned from 38.9 to 33.9 MHz, this is done via I2C Bus and the SIF
filter is switched from channel 2 to channel 1 ; this is done by pin 4 of TDA 936x. The tuner AGC time
constant is slower than for negative modulation, because the TDA936x reduces its AGC current. To even
slower the AGC time constant an extra series resistor R103 is added. To prevent IF overload when
jumping from a very strong transmitter to a weak transmitter a diode D101 has been added
The SAW filter ( SF1 ) has a double Nyquist slope at 38.9 MHz and 33.9 MHz needed for this
multistandard application. The disadvantage of this choice is that a 5.5 MHz trap filter ( Z501 ) is needed
to suppress the residual sound carrier in the video for B/G signals.

The controlling software via I2C bus selects the signal source :
- Video signal from tuner ( Pin 40 ).
- External video ( SCART 1 or 2 ) depending on Q508 base level.
- External SVHS from SCART 2.
The sound source switching is done in the MSP3415D ( I601 ), by the µ-Controller via I2C bus.
Fast R, G, B insertion : The external R, G, B insertion needs a fast switching and cannot be controlled by
the software ( instruction cycle of 1µ sec ). The fast switching pin 16 of SCART 1 is directly connected to
the TV processor pin 45 ( Fast blanking input ). The display is synchronised with the selected video
source, i.e. to get stable R, G, B inserted signal they must be synchronised with the selected video source.
The controlling software only enable or disable ( AV2, SVHS, or Forced RF source selected ) fast
blanking.
2-4 µ-Controller I/O pin configuration and function
The I/O pins of the µ-Controller can be configured in many way. All port functions can be individually
programmed by use of the SFR registers.
Each I/O port pin can be individually programmed in these configurations :
Open drain
In this mode, the port can function as in and output. It requires an external pull-up resistor. The maximum
allowable supply voltage for this pull up resistor is +5V.
So in this mode it is possible to interface a 5 Volt environment like I2C while the µ-Controller has a 3.3
Volt supply.

Push-Pull
The push pull mode can be used for output only. Both sinking and sourcing is active, which leads to sleep
slopes. The levels are 0 and Vddp, the supply voltage 3.3Volts.
High impedance
This mode can be used for input only operation of the port.
Special port for LED
Pin 10 has the same functionality as the general I/O pins but in addition, their current source and sink
capacity is 8 mA instead of 4 mA. These pins are used for driving LED’s via a series current limiting
resistor.

2-5 Sound processing
Analogue sound IF - input section
The input pins ANA_IN1+ and ANA_IN- offer the possibility to connect sound IF sources to the MSP
3415D. The analogue-to-digital conversion of the preselected sound IF signal is done by an A/D converter,
whose output is used to control an analogue automatic gain circuit (AGC), providing an optimal level for a
wide range of input levels.
Quadrature Mixers
The digital input coming from the integrated A/D converter may contain audio information at a frequency
range of theoretically 0 to 9 MHz corresponding to the selected standards. By means of two
programmable quadrature mixers, two different audio sources ; for example, NICAM and FM-mono, may
be shifted into baseband position.
- 28 -
Appendix
Service manual WP-795
Phase and AM discrimination
The filtered sound IF signals are demodulated by means of the phase and amplitude discriminator block.
On the output, the phase and amplitude is available for further processing. AM signals are derived from
the amplitude information, whereas the phase information serves for FM and NICAM demodulation.
NICAM decoder
In case of NICAM - mode, the phase samples are decoded according the DQPSK - coding scheme. The
output of this block contains the original NICAM bitstream.
DSP section
All audio baseband functions are performed by digital signal processing (DSP). The DSP section controls
the source and output selection, and the signals processing.
Sound Mode switching
In case of NICAM transmission, the controlling software read the bit error rate and the operation mode
from the NICAM Decoder. When the set is in “Auto detection” mode ( default mode after ATSS ) the
controlling software set automatically the sound mode ( NICAM mono, NICAM Dual 1 or NICAM Dual
2 ) depending on the transmitted mode.
In case of 2 Carrier FM transmission, the controlling software read the transmission mode and the signal
quality level from the Stereo Detection Register. When the set is in “Auto detection” mode the controlling
software set automatically the sound mode ( mono, Stereo, Dual 1, Dual 2 ) depending on the transmitted
mode.
In “Auto detection” mode the controlling software evaluate the signal quality and automatically switch to
the analogy sound carrier 1, if the transmission quality is too poor. To avoid unwanted automatic
switching the threshold levels mono to stereo and stereo to mono is different.
In “forced mono “ mode ( Red OSD in recall section ), the controlling software configure the MSP3415D
to demodulate only the analogue (FM or AM) sound carrier 1, no matter the signal quality. The sound
mode “ forced “ or “ Autodetect” is stored for each programme.

2-6 Sound amplification
The TDA8944J (TDA8946J) is a stereo BTL audio amplifier capable of delivering 2 x 7 W (2 x 15 W)
output power to an 8 Ω load at THD = 10%, using a 12 V power supply and an external heatsink. The
voltage gain is fixed at 32dB.
With the three-level MODE input the device can be switched from ‘standby’ to ‘mute’ and to ‘operating’
mode.
The TDA 8944J outputs are protected by an internal thermal shutdown protection mechanism and shortcircuit protection.
Power amplifier
The power amplifier is a Bridge Tied Load (BTL) amplifier with an all-NPN output stage, capable of
delivering a peak output current of 1.5 A.
The BTL principle offers the following advantages :
- Lower peak value of the supply current.
- The ripple frequency on the supply voltage is twice the signal frequency.
- No DC-blocking capacitor
- Good low frequency performance
Mode selection
The TDA894xJ has several functional modes, which can be selected by applying the proper DC voltage to
pin MODE.
Mute : In this mode the amplifier is DC biased but not operational (no audio output). This allows the input
coupling capacitors to be charged to avoid pop-noise. The devices is in mute mode when 2.5 V < VMODE <
(Vcc-1.5 V).
Operating : In this mode the amplifier is operating normally. The operating mode is activated at VMODE <
0.5 V.
2-7 Vertical deflection
The vertical driver circuit is a bridge configuration. The deflection coil is connected between the output
amplifiers, which are driven in phase opposition. The differential input circuit is voltage driven. The input
circuit is especially intended for direct connection to driver circuits which deliver symmetrical current
signals, but is also suitable for asymmetrical currents. The output current of these devices is converted to
voltages at the input pins via resistors R350 and R351. The differential input voltage is compared with the
output current through the deflection coils measured as voltage across R302, which provides internal
feedback information. The voltage across R302 is proportional to the output current.
Flyback voltage
The flyback voltage is determined by an additional supply voltage V flb. The principle of operation with
two supply voltages (class G) makes it possible to fix the supply voltage Vp optimum for the scan voltage
and the second supply voltage Vflb optimum for the flyback voltage. Using this method, very high
efficiency is achieved. The supply voltage Vflb is almost totally available as flyback voltage across the coil,
this being possible due to the absence of a coupling capacitor.
Protection
The output circuit has protection circuits for :
- Too high die temperature
- overvoltage of output stage A
Guard circuit
- 31 -
Appendix
Service manual WP-795
The guard signal is not used by the TDA936x to blank the screen in case of fault condition.
Damping resistor
For HF loop stability a damping resistor (R305) is connected across the deflection coil.
EAST-WEST Amplifier (TDA8358J only)
The East-West amplifier is current driven. It can only sink currents of the diode modulator circuit. A
feedback resistor R397 is connected between the input and output of this inverting amplifier in order to
convert the East-West correction input into an output voltage.

2-8 Power supply (STR F6653)
2-8 -1 STR-F6653 general description
The STR-F6653 is an hybrid IC with a build-in MOSFET and control IC, designed for flyback converter
type switch mode power supply applications.
2-8 -2Power supply primary part operations
An oscillator generates pulses signals which turn on and off a MOSFET transistor.
2-8 -2-1 Start -up circuit: VIN
The start-up circuit is used to start and stop the operation of the control IC, by detecting a voltage
appearing at VIN pin (pin 4).
- 33 -
Appendix
Service manual WP-795
When the power switch is pushed on, VIN increases slowly. During this time, C806 is charged through
R802.
As soon as VIN reaches 16V, the STR-F6653 control circuit starts operating. Then, VIN is obtained by
smoothing the winding voltage which appears between pin6 and pin7 of the SMPS transformer.
As this winding voltage does not increase to the set voltage immediately after the control circuit starts
operating, VIN starts dropping. However, as this winding voltage reaches the set value before VIN voltage
drops to the shutdown voltage (at 11V), the control circuit continues operating (see below VIN voltage at
start-up). R805 resistor prevents that VIN pin voltage varies according to the secondary side output current.
VIN must be set higher than the shutdown voltage (VIN (off) = 11Vmax) and lower than the O.V.P.

Appendix
Service manual WP-795
C When the MOSFET is ON, the STR-F6653 internal capacitor C1 is charged at the constant voltage
6.5V.
At the same time, the voltage at pin 1 (OCP / FB) increases with the same waveform as the MOSFET
drain current.
D When the pin 1 voltage reaches the threshold voltage VTH1 = 0.73V, the STR-F6653 internal
comparator 1 starts operating. The STR-F6653 internal oscillator is inverted and the MOSFET turns OFF.
E When the MOSFET turns OFF, charging of STR-F6653 internal capacitor C1 is released and C1
starts discharging by the STR-F6653 internal resistance R1. So, C1 voltage starts falling in accordance
with the gradient regulated by the constant discharging time of C1 and R1. So, this means that the fixed
time determined by C1 and R1 is the OFF-time of the MOSFET.
F When C1 voltage falls to around 3.7V, the STR-F6653 internal oscillator is reversed again and the
MOSFET turns ON. C1 is quickly charged to around 6.5V
The MOSFET continues to oscillate by repeating the above procedure.
2-8 -2-3 STR-F6653 protection circuits
• overcurrent protection function (OCP)
Overcurrent protection is performed pulse by pulse detecting at STR-F6653 pin 1 (OCP) the peak of the
MOSFET drain current in every pulse.
• latch circuit
This circuit sustains an output low from the STR-F6653 internal oscillator and stops operation of the
power supply when overvoltage protection (OVP) and thermal shutdown (TSD) circuit are under
operation
• thermal shutdown circuit (TSD)
This circuit triggers the latch circuit when the frame temperature of STR-F6653 IC exceeds 140°C
• overvoltage protection circuit (OVP)
This circuit triggers the latch circuit when the Vin voltage exceeds 22V (typ.)

2-9 1 TV start-up operations
2-9-1-1 Schematic diagram for start-up operations
2-9-1-2 TV start-up and microcontroller initialization
- When SW801 power switch is pushed, main AC voltage is applied to T801 transformer (after
rectification by D801...D804 diodes). Then, T801 SMPS transformer starts operating and supplies DC
voltage to I823 (3.3V regulator).
- This regulator provides 3.3V DC voltage to I501 microcontroller power supply pins (pins 54, 56, 61) and
to the reset pulse circuit which provides reset pulse to I501 microcontroller reset pin (pin 60).
- Then, the microcontroller starts its initialization. Its power pin (pin 63) is set to high which allows
delivery of power supply voltages (123V, 8V, 5V...). At this step, all IC’s start working but no picture
appears on screen: I501 IC doesn’t provide horizontal drive voltage.
- Then, the microcontroller consults I702 EEPROM via I2C bus to know the last TV set mode (normal run
mode or stand-by mode ) before switching off.
. If the TV set was on normal run mode before switching off, the microcontroller delivers
horizontal drive voltage at pin 33 and picture appears on screen.
- 37 -
Appendix
Service manual WP-795
. If the TV set was on stand-by mode before switching off, the microcontroller switches TV set to
stand-by mode, decreasing power pin voltage (pin 63). this matter will be explained on
paragraph 5-9-2-b.
2-9-1-3 Reset pulse circuit:
2-9-1-4 Reset pulse circuit operations description
- When DC supply voltage from I823 regulator starts rising (from 0V to 1.2V), no current flows through
D591 zener diode. So, Q510 is in off mode.
Also Vbe Q511 =Vcc/2 -Vcc = -Vcc/2 > -0.6V. So, Q511 is in off mode.
Then, no voltage reaches I501 pin 60.
- When this voltage reaches 1.2 V, Q510 stays in off mode
but Vbe Q511 = -0.6V. So, Q511 is switched on and starts driving DC supply voltage to I501 pin 60.
- 38 -
Appendix
Service manual WP-795
- When the DC supply voltage reaches (2.4V +0.6V ) =3.0V, Q510 starts conducting but as the Q511
base-emitter voltage is the same as the collector-emitter voltage of the saturated Q510, Q511 switches
off and no voltage reaches I501 pin 60.
- If the DC supply voltage decreases below 3 V, Q510 switches off immediately. Q511 starts conducting,
pulling I501 pin 60 high.
At the same time, it discharges the reset capacitor C501. Discharging this capacitor is necessary to
garantee a defined reset pulse duration.
2-9-2 TV normal run and stand-by mode operations
Depending on remote control commands, I501 microcontroller part pin 63 (power) is set to:
- high for normal run mode
- low for stand-by mode

On normal run mode, I501 microcontroller pin 63 (power) is set to high
•
So, I810 controlled rectifier is not conducting
- Q809 is conducting. So, Q808 is not conducting and Q807 is conducting
- So, Q807 collector is connected to the ground and I810 controlled rectifier gate pin is set
to low (no conducting)
•
So, current from 11V DC voltage (from T801 SMPS transformer pin 13) does not flow through Q811
and Q810 transistors but flows through I806 IC error amplifier
- Q809 is conducting. So, Q810 is not conducting and no current flows from Q810 collector
to the ground
Therefore, the power circuit diagram is the following one:

2-9-2-2-2 TV set stand-by mode operations
-On stand-by mode, I501 microcontroller pin 63 (power) is set to low.
- So, Q809 collector is set to high.
-Then, I810 controlled rectifier gate pin is set to high and I810 is conducting.
- So, current flows from pin 16 SMPS transformer to the ground via I804 photo coupler and Q810 and
Q811 transistors (which are conducting).
- In these conditions, I801 delivers pulses on light mode and T801 produces voltages with reduced power.
- As I810 is conducting, current flows also from pin 16 SMPS transformer to I823 (3.3V regulator) for
I501 µcom, IR receiver and front mask buttons supply voltage (then, remote control or front mask
buttons can be activated to leave stand-by mode).
