Service manual SC-150 5-3 Video - VCT description 5-3-1 Introduction The VCT 38xxA includes complete video, display, and deflection processing. All processing is done digitally, the video front-end and video back-end are interfacing to the analogue world. Most functions can be controlled by software via I 2 C bus slave interface.
Service manual SC-150 5-3-8 Adaptive Comb Filter (VCT3834A only) The adaptive comb filter is used for high-quality luminance/chrominance separation for PAL or NTSC signals. The comb filter improves the luminance resolution (bandwidth) and reduces interferences like cross-luminance and cross-color artefacts. The adaptive algorithm can eliminate most of the mentioned errors without introducing new artefacts or noise. The filter uses two line delays to process the information of three adjacent video lines.
Service manual SC-150 5-3-11 Video Sync Processing To extract the sync information from the video signal, a linear phase low-pass filter eliminates all noise and video contents above 1 MHz. The sync is separated by a slicer; the sync phase is measured. A variable window can be selected to improve the noise immunity of the slicer. The phase comparator measures the falling edge of sync, as well as the integrated sync pulse.
Service manual SC-150 5-3-15 CRT Measurement and Control The display processor is equipped with an 8-bit ADC for all measuring purposes. The ADC is connected to the SENSE input pin. Cutoff and white-drive current measurement are carried out during the vertical blanking interval. 5-3-16 Average Beam Current Limiter The average beam current limiter (BCL) uses the SENSE input for the beam current measurement. The BCL uses a different filter to average the beam current during the active picture.
Service manual SC-150 5-3-20 EHT Compensation The vertical waveform can be scaled according to the average beam current. This is used to compensate the effects of electric high-tension changes due to beam current variations. EHT compensation for East/West deflection is done with an offset corresponding to the average beam current. 5-3-21 Reset Function Reset of all VDP functions is performed by the RESQ pin. When this pin becomes active, all internal registers and counters are lost.
Service manual SC-150 5-4-3 - Controller I/O pin configuration and function There exist different kinds of ports. The universal ports serve as digital I/O and have additional special input and output functions. A subset of the universal ports serves as input for the analogue-to-digital converter.

The output of this block contains the original NICAM bitstream. 5-6-5 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.
Service manual SC-150 5-7-2 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 device 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.
Service manual SC-150 5-9 Power supply (STR F6654) 5-9-1 STR-F6654 general description The STR-F6654 is an hybrid IC with a build-in MOSFET and control IC, designed for flyback converter type switch mode power supply applications. 5-9-2 Power supply primary part operations An oscillator generates pulses signals which turn on and off a MOSFET transistor.
Service manual SC-150 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-F6654 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.

Service manual SC-150 When the MOSFET is ON, the STR-F6654 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-F6654 internal comparator 1 starts operating. The STR-F6654 internal oscillator is inverted and the MOSFET turns OFF.
Service manual SC-150 5-10 TV start-up, TV normal run and stand by mode operations 5-10-1 TV start-up operations * Schematic diagram for start-up operations * 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 (5V regulator). - This regulator provides 5V / 3.
Service manual SC-150 . If the TV set was on normal run mode before switching off, the microcontroller delivers horizontal drive voltage at pin 24 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 1).
Service manual SC-150 On normal run mode, I501 microcontroller pin 1 (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 14V 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.
Service manual SC-150 * power supply functioning during TV set normal run mode - I801 transmits controlled pulses to T801 which generates DC voltages after rectifications by secondary part diodes and electro capacitors (by example by D820 and C813 on 143V supply voltage line). - 8V, 5V, 3.3V supply voltage lines have stabilized voltages obtained by I820, I822, I823 voltage regulators. - On 143V supply voltage line, R823 resistor has been chosen to reach exact DC voltage required on this line.
