1.2 Normal / Controlled Operation For the power supply of this TV receiver a blocking oscillator-type converter power supply with a switching frequency of 50kHz approximately is used (at normal operation and a mains voltage of 230V). The collector contact of the power transistor T665 is connected via the primary winding 3/1 of the blocking oscillator-type transformer TR601 to the rectified mains voltage, D621D624. At a mains voltage of 230V the voltage level present at the charging electrolytic capacitor C626 is approx. +320V.

2. System Control

2.1 Microcomputer The mask-programmed 8-bit Microcomputer IC850 (SDA5222 without Text) decodes the commands entered on the keyboard and also the infra-red remote control commands from the IR-receiver. It is also responsible for the total system control and the on-screen display (OSD). All data for the programme positions and the options are stored in the NVM (Non Volatile Memory). The teletext (Videotext) IC is integrated in SDA5252. The correct operation of the microcomputer depends on the following conditions: - Supply voltage +5V/H at Pin 37 - Oscillator frequency 18MHz at Pins 12, 13 - Reset pulse: Every time the TV receiver is switched on with the mains button, the processor is reset on Pin 1 by the reset pulse. - I2C-bus: The I2C-bus is a bidirectional two-lead bus consisting of the SDA (System Data) lead and the SCL (System Clock) lead. Checking the operation of the processor IC850: The I2C-bus leads are connected via the pull-up resistors CR869 and CR868 to +5V/H. The data traffic is controlled from the processor which also generates the SCL bus clock. The only way to check the data and clock leads when servicing is by measuring the TTL-levels (L 0.8V; H 3.5V). Service note: The I2C-bus data is also present without a command from the IR remote control handset. If no data is carried on the bus leads there may be a short circuit. To localize the fault, the modules and components connected to the data bus must be unsoldered or unplugged one after the other. 2.2 Initialisation of the Processor after Switching On When the TV is switched on, the +5V/H voltage builds up, the IC850-(15) is reset, and the programme sequence is started. With the start command, the processor feeds out a "High" level at Pin 40 and the voltage UStandby starts the TV via CT826, IC676-(1) by means of the voltages +B, 12V (see Power Supply). After switching on, the processor (IC850) transfers the operating data from the internal memory via the I2C-bus to the bus-controlled modules and circuits.

2.3 Switching over of the CCVS Signals to the Scart Socket A "High"-level switching voltage UFBAS at IC850-(16) causes the CCVS signal FBASSC to be switched to output pin 19 of the Scart socket. 2.4 Entering Commands The keyboard is connected to the unswitched voltage +5V/H. By evaluating the different voltage levels, the processor IC850-(27),-(28) knows which button on the keyboard has been pressed. The remote control commands are amplified by the infrared receiver IC810 and decoded at Pin 8 of the microprocessor. 2.5 Teletext IC850 (SDA5252) The IC850 (SDA5252) contains a 1-page Teletext-IC. The On Screen Display is subdivided into lines and columns. For positioning and synchronising the teletext display, horizontal and vertical reference pulses are fed to IC850-(45, 46). Activation of the teletext is effected internally via the I2C-bus. Via pin 30, the SDA5252 scans the CCVS signal for teletext data. 2.6 On Screen Display (OSD) For displaying data on the screen, the switching voltage "UData" IC850-(50) supplies a "High" level switching IC150-(21) 2V to RGB mode. The character generator feeds out the display data via the output ports 47, 48, 49 of the microprocessor at an amplitude of 4.5V to the RGB inputs IC150-(22), -(23), -(24), approx. 450mV. 2.7 Protection Circuit USchutz The base of the transistor T511 is connected via R511 to the low-end point of the vertical output stage, and via R512, D512, D513 to the reference pulse F from the horizontal output stage. In the case of any failure, a base voltage of 0.6V and higher switches the transistor on; via its collector the transistor switches IC850-(32) to ground. The P then switches the TV to standby. If the voltage +D fails there is no direct voltage present at the output of the vertical output stage IC400-(5) and consequently the proctection circuit input IC850-(32) is pulled to ground. At the same time the collector (SB lead) is connected via R513, D514, and CD516 to the low-end point of the high-tension winding. When the Zener voltage is exceeded due to too high a beam current the collector voltage decreases to 0V so that the TV switches to standby.

3. TV Signal Processor TDA8362A
3.1 Overview: With this TV design the whole signal processing is carried out in a single IC, i.e. the TV Signal Processor TDA 8362A. It accommodates the following stages: IF Signal: - IF amplifier - Demodulator - AFC - AGC - Coincidence identification CCVS Signal: - Signal source switch for the CCVS signal - Luminance processing - Colour demodulation - Chrominance processing - Colour contrast control - RGB matrix - C-AV input - Signal source switch for RGB signals - Brightness control - Contrast control - Black level control (cut-off) Sound: - Signal source switch for the sound - Sound demodulation - Volume control Deflection: - Sync separator - Line oscillator - 1 phase control - 2 phase control - Trigger pulse generation for the line output stage - Line counter - Saw-tooth generation for the vertical deflection - Drive signal for the field output stage Dependent on the associated circuitry, the IC is also able to process PAL, NTSC and SECAM signals. 3.2 IF The IF spectrum of frequencies is fed through a symmetrical path from the tuner Pins 11 and 10 via the filter F901 and the Surface Acoustic Wave filter F906. The signal formed by the Surface Acoustic Wave filter is applied symmetrically to Pins 45 and 46 of the signal processor. The demodulation of the CCVS signal is carried out in a product demodulator. Bild ZF und Demodulation Vision IF and Demodulation
The required demodulator circuit F130 is connected to Pin 2 and Pin 3. The demodulated signal passes through an amplifier and is then present at Pin 7 of the IC (BB). The IC identifies the synchronising signal internally and for this reason, feedback of the line flyback pulse for gating purposes is not necessary. Corresponding to the synchronising signal level a control voltage is generated. This control voltage first acts on the controlled input amplifier of the IF. Via Pin 49 a reference threshold URV is set. Below this threshold, only the input amplifier of the IF is regulated. If the threshold is exceeded, the control voltage Ut is applied from Pin 47 to the tuner. Pin 47 is an open collector output. In uncontrolled condition, the voltage is approximately 5V. With increasing input amplitude the AGC level decreases. The direct voltage for automatic frequency control (AFC) is generated in the demodulator. Pin 9 feeds out this signal as a current signal. When the received frequency increases the control voltage for AFC decreases. The processor IC850 evaluates the signal and fine tunes the tuner accordingly. The demodulated signal is examined by the sync detector for the presence of synchronising signals. If no such signals are present, the IC150-(4) switches to "Low". By this level the processor IC850-(33) can identify that the coincidence signal is missing and mutes the sound. 3.3 CCVS Signal The demodulated CCVS signal leaves IC150-(7), TDA8362A, as a baseband signal together with the sound-IF. In the following path, the sound signal is separated from the CCVS signal. After the transistor CT921 and the sound trap F923 and F924 the signal path divides. Via the transistor CT110 and IC2807 (optionally) it is fed through to the videotext decoder IC850-(30) as FBASSC signal, and via the transistors CT963, CT962 it is supplied to the Scart socket pin 19. At the signal source switch IC150-(13), the signal is present as FBAS (CCVS). The second input of the signal source switch Pin 15 is connected to the Scart socket pin 20. At IC150-(16), the processor IC850-(42), voltage UVQ, transistor CT840 decides as to whether the signal from the tuner or the external signal is processed. 3.4 External CCVS Signal At the signal source switch IC150-(15) either an external CCVS signal from the Scart socket or the RF-CCVS signal is present. The voltage UVQ at IC150-(16) decides which signal shall be passed on, the CCVS signal from the Scart socket or else the RF-CCVS signal. IC150-(16) "Low", the internal signal is selected; IC150-(16) "High", the external signal is passed on. Attention: If the option "Decoder On" has been selected the TV expects the signal to come from the Scart socket. However the CCVS signal from the tuner can be measured at output Pin 19 of the Scart socket.

3.13 The Super Sand Castle - SSC The 3-level SSC signal IC150-(38) is a composite pulse consisting of the line flyback, the field flyback, and the burst key pulses. The line flyback pulse (H-Sync) is fed through T523, CR163 to IC150. The field flyback and burst key pulses are generated inside the IC. If the field deflection stage fails, IC400-(7) pulls the SSC level to "Low" via R401 and thus blanks the CRT at IC150-(18, 19, 20) RGB. In doing so, the analog values are set to "Low". 3.14 Setting of the Cut Off Voltage An automatic cut-off controlling stage ensures that the static working points of the CRT are held stable. For this, IC150 feeds out a pulse to the R, G, B cathodes during the lines 23, 24 and 25 to measure the beam current of each system (approx. 10A). The cut-off current during the measuring lines is fed via the resistor CR156 to IC150-(14). The IC compares this voltage with an internal reference value to determine the working point for the black level of the video output stages and the cut-off voltage of the CRT respectively. 3.15 The HDR Output Stage Following an amplification stage the horizontal drive signal for the line output transistor is provided at Pin 37. 3.16 The Field Deflection Stage In this circuit concept, the field sync generator is substituted by a line counter. When no synchronising signals are received the line oscillator is free running. From this line oscillator the "vertical oscillator" is derived by counting the number of lines. After having counted 312 lines, the counter feeds out a field sync signal so that the horizontal and also the vertical deflection is achieved without using an external synchronising signal.
On reception of a synchronising signal, the line oscillator will first be synchronised. In this case too, the line counter supplies a field deflection signal. As soon as a field synchronising signal is obtained the sawtooth generator will no longer be triggered by the line counter but directly by the field sync signal. The saw-tooth generator is made up of a constant current source which is used to charge and discharge an external capacitor. The charging period is determined by the field sync signal. The field deflection signal can be measured at the capacitor C158, IC150-(43). Adjustment of the field amplitude at the field output stage IC400 is possible by influencing the field saw-tooth voltage. This alteration must be carried out before the field output stage. For this, a feedback signal from IC400 is present at IC150-(42) for negative feedback. Similar to an operational amplifier connected to the negative input, this technique allows to set the desired parameters. 3.17 Non-Interlace Compensation with Teletext (25Hz Modulation) When a teletext (videotext) signal is displayed on the screen, the teletext signal would continuously change by one line upwards and downwards (non-interlaced teletext signal). To avoid the signal changing the line, the teletext IC850-(52) supplies a 25Hz switching signal to IC150-(43). From this U25Hz switching voltage, a small DC voltage offset is derived for the deflection saw-tooth. This offset effects an upward shift of the first half-field so that the even-numbered and odd-numbered lines are superimposed on each other. 3.18 Coincidence The coincidence information is generated in the IF stage and fed out on IC150-(4).

Die Hochspannung fuer die Bildroehre und die damit auftretende Roentgenstrahlung ist abhaengig von der exakten Einstellung der Netzteilspannung +A. Schutzschaltungen im Geraet duerfen nur kurzzeitig ausser Betrieb gesetzt werden, um Folgeschaeden am Chassis oder an der Bildroehre zu vermeiden. The high tension for the picture tube and thus the developing X-radiation depends on the precise adjustment of the +A power supply. To avoid consequential damages to the chassis or the picture tube the integrated protective circuits are allowed to be put out of operation only for a short time. 131196
