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 sys...

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 cont...

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. 7200). Tuner AGC (Autom...

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)...

The following additional controls are used: z 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 measu...

Inside IC 7200 part D the vertical and horizontalsync pulses are separated. These ‘H’ and ‘V’ signalsare synchronised with the incoming CVBS signal. They are then fedto the H- and V-drive circuits and to the OSD/TXT circuitfor synchronization of the On Screen Display and Teletext (CC)informationrmat...

white line. During t3 - t5, C2490//2458 is chargedvia R3459. 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-vol...

Two protections are built-in for the E/W circuit:over-current and over-voltage protection. See paragraph 9.3.5. Panorama The panorama function is only used in 16:9sets. This is a function to enable the 4:3 and Super-Wide feature.It drives the ‘Bass_panorama’ line, toactivate relay 1400. When this re...

The ‘MainSupply’ line is the referencevoltage for the power supply. It is sampled by resistors 3543 and3544 and fed to the input of the regulator 7540 / 6540.This regulator drives the feedback optocoupler 7515 to set the feedbackcontrol voltage on pin 3 of 7520. The power supply in the set is ‘on’ a...

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 ...

Figure: In the Quasi-Resonant mode each period can be dividedinto four different time intervals, in chronological order: z Interval 1: t0 < t < t1primary stroke At the beginning of the first interval,the MOSFET is switched ‘on’ and energy is storedin the primary inductance (magnetization). At ...

Operation The supply can run in three different modesdepending on the output power: z Quasi-Resonant mode (QR) TheQR mode, described above, is used during normal operation. Thiswill give a high efficiency. z Frequency Reductionmode (FR) The FR mode (also called VCO mode) is implementedto decrease th...

The internal currentsource charges the V CC capacitor(also the soft start capacitor is recharged). Once the V CC capacito...

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 voltag...

During the primary stroke, the rectified ACinput voltage is measured by sensing the current drawn from pin4 (DEM). This current is dependent on the voltage on pin 9 of transformer 5520and the value of R3522. The current informationrmation is used toadjust the peak drain current, which is measured vi...

Protection Events Several protection events are controlled bythe UOC: z BC protection , to protect thepicture tube from a too high beam current. The UOC has the capabilityof measuring the normal back level current during the vertical flyback.So if for some reason the CRT circuit is malfunctioning (i...
