  • Page 30: Audio Signal Processing

    SPMS Figure: The S8/T8 is divided into 2 basic systems, i.e.mono and stereo sound. While the audio processing for the mono soundis done in the audio block of the UOC, an external audio processingIC is used for stereo sets. The tuning system features 181 channels with on-screen display.The main tuning system uses a tuner, a microcomputer, and a memoryIC mounted on the main panel.

  • Page 31: Video Signal Processing

    SPMS In mono sets, the signal goes via the SAW filter(position 1002), to the audio demodulator part of the UOC IC 7200.The audio output on pin 48 goes, via the smart sound circuit (7941for Bass and 7942 for Treble) and buffer 7943, to the audio amplifier(AN7523 at position 7902). The volume level is controlled at this IC (pin 9) by a ‘VolumeMute’...
  • Page 32 SPMS The incoming RF signal goes to the tuner (pos.1000), where the 45.75 MHz IF signal is developed and amplified.The IF signals then exits the tuner from pin 11 to pass throughthe SAW filters (pos. 1002). The shaped signal is then applied to theIF processor part of the UOC (pos.
  • Page 33 SPMS Page 6 of 32 Figure: Once the signal source is selected, a chroma filter calibrationis performed. The received color burst sub-carrier frequency is usedfor this. Correspondingly, the chroma band pass filter for PAL/NTSCprocessing or the cloche filter for SECAM processing is switchedon. The selected luminance (Y) signal is supplied to the horizontaland vertical synchronization processing circuit and to the luminanceprocessing circuit.
  • Page 34 SPMS Luminance / Chrominance signalprocessing The output of the YUV separator is fed to theinternal YUV switch, which switches between the output of the YUV separatoror the external YUV (for DVD or PIP) on pins 51-53. Pin 50 is theinput for the insertion control signal called ‘FBL-1’. Whenthis signal level becomes higher than 0.9 V (but less than 3 V),the RGB signals at pins 51, 52 and 53 are inserted into the pictureby using the internal switches.
  • Page 35 SPMS The following additional controls are used: Black current calibration loop Becauseof the 2-point black current stabilization circuit, both the blacklevel and the amplitude of the RGB output signals depend on the drivecharacteristics of the picture tube. The system checks whether thereturning measuring currents meet the requirements, and adapt theoutput level and gain of the circuit when necessary.

Vertical drive A divider circuit performs the vertical synchronization.The vertical ramp generator needs an external resistor (R3245, pin 20)and capacitor (C2244, pin 21). A differential output is availableat pins 16 and 17, which are DC-coupled with the vertical outputstage.

At the moment of the flyback, C2490//2458is subjected to the negative voltage pulses of the parabola as aresult of which D6465 and D6466 are conducting and C2490//2458is switched in parallel with C2456//2457. Thisis the moment the high-voltage diodes are conducting.

This is a function to enable the 4:3 and Super- Wide feature.It drives the ‘Bass_panorama’ line, toactivate relay 1400.

The frequency of operation varies with the circuit load.This ‘Quasi-Resonant Flyback’ behavior has someimportant benefits compared to a ‘hard switching’ fixedfrequency Flyback converter. The efficiency can be improved up to90%, which results in lower power consumption.

  • Page 42 SPMS Page 15 of 32 Figure: Figure: Degaussing When the set is switched on, the degaussingrelay 1515 is immediately activated as transistor 7580 is conducting.Due to the RC-time of R3580 and C2580, it will last about 3 to 4 secondsbefore transistor 7580 is switched off. Basic IC Functionality For a clear understanding of the Quasi-Resonantbehavior, it is possible to explain it by a simplified circuit diagram(see Figure below).

Whenthis line is pulled high, the base of Q7541 is allowed to go high.This is triggered by the current from collector Q7542. When Q7541 turns ‘on’,the opto-coupler (7515) is activated, sending a large current signalto pin 3 (Ctrl).

  • Page 50 SPMS Page 23 of 32 Figure: Over Voltage Protection The Over Voltage Protection ensures that theoutput voltage will remain below an adjustable level. This worksby sensing the auxiliary voltage via the current flowing into pin4 (DEM) during the secondary stroke. This voltage is a well-defined replicaof the output voltage. Any voltage spikes are averaged by an internalfilter.
