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 22-23 kV (14" or ) 24-26 kV (20"- 21" at max beam current. The high voltage must not, under any circumstances, exceed 27.5 kV (14" ) , 20" 29KV (21" 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. Potentials of high voltage are present when this receiver is operating. Operation of the receiver outside the cabinet or with the back cover 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. 2. If any Fuse in this TV receiver is blown, replace it with the FUSE specified in the Replacement Parts List. 3. When replacing a high wattage resistor (oxide metal film resistor) in circuit board, keep the resistor body 10 mm away from the circuit board. 4. Keep wires away from high voltage or high temperature components. 5. This receiver must operate under AC 230 volts, 5O Hz. NEVER connect to a DC supply of any other voltage or frequency.
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.

ATSS sorting method
The TV set sweeps all the TV bands from beginning of VHF to the 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 checks 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 into 4 groups : Group I : 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 : Contains all the programs with a strong signal strength which are not listed in group I. Group III : 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.

APPENDIX FUNCTIONAL DESCRIPTION
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 (33.9 MHz for system L'and 38.9 MHz for all other systems). Because of the internal VCO, the IF circuit has a high immunity to EMC interference.
1. IF demodulator and audio amplifier
The FM demodulator is realised as a narrow band PLL with external loop filter, which provides the necessary selectivity without using an extra band pass filter. To obtain good selectivity a linear phase detector and a constant input signal amplitude are required. For this reason the intercarrier signal is internally supplied to the demodulator via a gain controlled amplifier and AGC circuit. The nominal frequency of the demodulator is set via a gain controlled amplifier and AGC circuit. The nominal frequency of the demodulator is tuned to the required frequency (5.5 / 6.0 / 6.5 MHz) by means of a calibration circuit which uses the clock frequency of the microcontroller as a reference. Selection of the required frequency is done by the controlling software.
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.
1
APPENDIX FUNCTIONAL DESCRIPTION
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. The following geometry parameters can be adjusted: · Horizontal shift · Vertical amplitude · Vertical slope · S-correction · Vertical shift
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 oversaturation occurring 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 µ-Controller 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 ). 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 reception, to obtain a good suppression of cross colour effects. The demodulated colour difference signals are internally supplied to the delay line.

APPENDIX FUNCTIONAL DESCRIPTION
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. IF
The TDA9361/TDA9381 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 TV-Processor 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 window 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 a channel with the TV search function ( manual or ATSS ) or by using the direct channel entry to enable the Automatic Frequency Control. SAW filters SF01 SF02 Ref.

APPENDIX FUNCTIONAL DESCRIPTION
For SECAM L and L'the TDA9361/TDA9381 is switched to positive modulation via I2C bus. SECAM L'transmission 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 9361. The tuner AGC time constant is slower for positive than for negative modulation, because the TDA9361 reduces its AGC current. To make the AGC time constant even slower 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. ************************************************************************************************************************************************
3. Source switching
Video : The TDA9361/TDA9381 has only one external video input. The SCART video in pin (#20) is connected to the front RCA video input. The controlling software via I2C bus selects the signal source : - Video signal from tuner ( Pin 40 ). - External video. - External SVHS from SCART.
The sound source switching is done in the video processor part and in the AM demodulator by the µ-Controller via I2C bus. The video processor pin 28 has multiple functions and provides in this application - Deemphasis time constant - Audio monitor output - External AM input - Deemphasis time constant : The time constant is given by the capacitor C504, needed to obtain the 54µs time constant for standard PAL signal. - Audio monitor output : the nominal output signal is 500 mVrms, for all standards. The signal is also internally connected through to the audio switch. This signal is not controlled by the volume setting and can be used for SCART audio output. The signal is buffered to avoid influencing the deemphasis time constant and to adjust the output level. - External AM input : By software the deemphasis pin can be converted into an input pin. External AM signal for SECAM L/L'is directly connected to this pin. In this configuration the FM sound is internally muted, DC level remains at 3Vdc. An external sound signal of 500mVrms is applied to pin 35 via a coupling capacitor. The input impedance of this pin is 25K typical. Switching between internal FM, external AM or external audio from SCART is controlled internally by software.

APPENDIX FUNCTIONAL DESCRIPTION
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 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 signal insertion they must be synchronised with the selected video source.
4. µ-Controller I/O pin configuration and function
The I/O pins of the µ-Controller can be configured in many ways. All port functions can be individually programmed by the controlling software. Each I/O port pin can be individually programmed in these configurations : Open drain In this mode, the port can function as input 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 steep 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 and 11 have 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' via a series current limiting resistor. s

In FM mode the microcontroller is internally grounded to pin 4. The TDA9830 output is muted
6. Sound amplification
The device TDA7267A is a mono audio amplifier in powerDIP package specially designed for TV application. Thanks to the fully complementary output configuration the device delivers a rail to rail voltage swing without need of bootstrap capacitors. No external heat sink is needed as the Cu ground plane of the PCB is used as heat dissipation.
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 Vfb. 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 Vfb optimum for the flyback voltage. Using this method, very high efficiency is achieved. The supply voltage Vfb 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 The guard signal is not used by the TDA9361/ TDA9381 to blank the screen in case of a fault condition. Damping resistor For HF loop stability a damping resistor (R305) is connected across the deflection coil.

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. 8-2. Power supply primary part operations An oscillator generates pulse signals which turn on and off a MOSFET transistor. 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 the VIN pin (pin 4).

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 pin 6 and pin 7 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). Resistor R805 prevents variations of voltage at the VIN pin, as some regulation of the SMPS transformer occurs due to secondary side output current VIN must be set higher than the shutdown voltage (VIN (off) = 11Vmax) and lower than the O.V.P. (overvoltage protection) operating voltage (VOVP = 20.5Vmin).

Waveforms during oscillating operation
- 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. - 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. - 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 to 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. - 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.

9-1-2. TV start-up and microcontroller initialisation
- 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 initialisation. Its power pin (pin 63) is set to high which allows delivery of power supply voltages (110/123V, 8V, 5V...). At this step, all IC' start working but no picture appears on screen: I501 IC doesn' provide horizons t tal 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. . 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 in paragraph 2.2.

APPENDIX FUNCTIONAL DESCRIPTION
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. - 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 guarantee a defined reset pulse duration.

APPENDIX FUNCTIONAL DESCRIPTION
In 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:
