and vertical deflections

The block diagram in Fig.1 shows how the TV set circuit works divided into 9 basic circuits.

6.1 - POWER SUPPLY

IC901, IC902, IC903, T901, Q901 and surrounding components (9xx).

This is a switching mode power supply designed to operate in AC power source from 99 Volts to 242 Volts and 50/60 Hertz. The main device is the TDA16846 (controller for switching mode power supplies).

In stand-by mode , the micro-controller disables the IC904 (+9Vdc regulator) ,turning-off the tuner ,the stereo decoder ,the AV switches and the TV signal processor circuit . In this condition ,the horizontal and vertical deflections and audio output circuits are stopped with a low current consumption . Only the micro-controller is active .

The power-on is activate by the micro-controller (pin45) though the remote control or the power switch in the front panel ,that turns-on the +9V supply waking up the circuit .

The output voltages are controlled by the IC901 through the opto coupler feedback (IC902) and a reference voltage given by IC903 .

The basic output voltages are:

1. +130 Volts for the horizontal circuit;

2. +18 Volts for audio output circuits;

3. +9 Volts for TV signal processor, stereo decoder and AV circuits;

4. +5 Volts for microprocessor and memory circuits.

There are 3 basic protection mode:

1. AC power source undervoltage: the power supply will turn-off when the AC source is less than 90 Volts;

2. Power consumption limit: when the power consumption exceed 20% of the normal value;

3. Overvoltage outputs shutdown: when the output voltages exceed 20% of the normal values.

6.2 - TV SIGNAL PROCESSOR

IC501 and surrounding components.

The main device is the TDA8843, that combines all the functions for a multi-system color TV application with closed caption.

Page 8

The highlights of this device are:

-I2C bus serial I/O;

-Multi-standard vision IF circuit (45.75 MHz) with PLL demodulator;

-PAL/NTSC color decoder with automatic search system;

-Integrated luminance and chrominance circuit;

-RGB control circuit;

-8V supply voltage;

-Horizontal and vertical geometry processing.

6.3 – MICRO-CONTROLLER

IC101, and surrounding components.

This is a 8bit micro-controller dedicated for TV applications (M37274MA). It controls all the circuits by two I2C bus lines. Main features:

- 8MHz crystal oscillator for internal timing.

- internal memory: ROM 40Kbytes and RAM 768 bytes.

- closed caption decoder.

- 5V supply voltage.

- 32KHz crystal oscillator for clock functions.

- high performance OSD.

An external E2PROM (IC102) with 4 Kb is used to keep the setup and calibration configuration by I2C bus (channels, volume, horizontal and vertical geometry, etc.).

Front panel buttons and IR decoders are also realized by IC101.

6.4 - TUNER

TU201, and surrounding components.

This is a standard Frequency Synthesizer Tuner (FST Tuner) which covers VHF and UHF channels, including cable channels (frequency range from 55.25 MHz to 801.25 MHz).

This device is controlled by I2C bus. The IF output signal (45.75 MHz) is connected to the IC501 through a SAW filter (MF201).

6.5 - AV SWITCHES

IC470 , IC480 and surrounding components.

The external audio and video signals (AV1, AV2, AV3) are selected by the Micro Controller using two output signals ( pin47 av2 and pin48 av1, IC101). The video signals are selected using IC480 (LA7221), and the audio signals are selected using the IC470 (4052). The selected video signal is connected to the TV signal processor external video input (pin17) and the selected audio signal is connected to the stereo decoder IC450 (pins 12 and 41).

6.6 - STEREO DECODER

IC450 and surrounding components.

The main device is TDA9855 (stereo / sap decoder with DBX noise reduction system). Using I2C bus, the IC101 can identify a stereo and SAP signals. This device combines stereo decoder and audio processor with automatic volume level control, special effects, volume/balance controls, bass control and treble control. Q450 and Q450R are buffers for the audio output jacks (JA450).

6.7 - AUDIO OUTPUT

IC401, SP401, SP401R and surrounding components.

The main device is TDA2616 (stereo amplifier). The output signal is a 5+5 Watts with a 8 ohms speakers. The input signals come from the stereo decoder (IC450 pins6 and 47).

Page 9

This circuit uses external mute system (Q410) to minimize speaker noise during turn on/off.

6.8 - VIDEO OUTPUT

Q810, Q811, Q812, Q820, Q821, Q822, Q830, Q831, Q832 and surrounding components.

The RGB signals from the signal processor (pins 19,20,21) ,are amplified to the CRT using a cascode transistors configuration.

6.9 - HORIZONTAL AND VERTICAL DEFLECTIONS

IC601, T701, T702, Q701 and surrounding components.

Vertical deflection circuit uses a TDA8177F (IC601 - vertical deflection booster) and operates with around 24V and provides output current to drive the yoke. The input signals are vertical drive + / - from the TV signal processor (pin46 and 47 of IC501).

Horizontal deflection circuit uses 15.7KHz signal (HOUT_pin40 IC501) to drive the fly back transformer (T701) and provides the output current to drive horizontal deflection coil (yoke) and others CTR voltages (HV, focus, screen and etc.).

The vertical deflection circuit has one protection mode (turn-off the power supply if a fault situation is detected) and the horizontal deflection circuit has two protection modes:

-turn-off the power supply if a HV over voltage is detected (X-ray protection);

-turn-off the power supply if a horizontal drive transistor (Q701) overstress is detected.

2. DISASSEMBLY INSTRUCTIONS

Removal of mechanical parts and P.C. Boards.

2.1 Back Cabinet (refer to figure 2.1)

> Remove the screws, which secure the back cabinet to the front cabinet. > Remove the screws, which secure the rear A/V input and output connectors. > Remove the back cabinet.

2.2 CRT PCB (refer to figure 2.2/2.3)

Caution: Before removing the anode cap, discharge electricity because it contains a high voltage. Before attempting to remove

or repair any PCB, unplug the power cord from the AC source.

> Remove the anode cap. > Disconnect the ground connector (CM801). > Remove the CRT PCB.

2.3 Main PCB (refer to figure 2.2/2.3)

> Disconnect the following connectors: CM901, CM902, CM701, CM601, CM401 and CM402. > Unlock the PCB from the cabinet (both sides of the board). > Remove the Main PCB.

2.4 CRT (refer to figure 2.4)

> Remove the four (4) screws. > Remove the CRT.

Note: The REMOVAL OF THE ANODE CAP - After turning the power OFF, there might still be a potential voltage that is very

dangerous. When removing the ANODE CAP, make sure to discharge the anode's cap potential voltage. Do not use pliers to loosen or tighten the anode cap terminal. This may cause damage to the spring.
