Board

Module

Main Board module is the chassis part of LCD TV signal processing. Under the control of

the system control circuit, It undertakes the task of converting the external input signal into

the unified digital signal that the LCD screen could identify. Mainboard controls the whole

machine through MCU bus, decode VIDEO signal, controls the image analog quantity

(brightness, contrast, chroma, hue, definition etc), adjusts white balance, generates OSD,

de-interlaces signal, converts signal frequency, and finishes signal A/D and D/A conversion,

video enhancement, LVDS signal coding and output; it has Scart interface, “S” terminal, AV

terminal, Ypbpr, HDMI and PC interface, Tuner input, sound demodulation, sound effect

treatment, sound power amplifier, and online upgrade of program.

The remote reception board module is constituted by an indicator-light and a remote

reception-head. Customer could manipulate the LCD TV by using remote controller very

conveniently. By the color of the indicator light, the operation mode of the LCD TV could be

udged (red is standby, green is power on).

Convert the 100V～240V AC into DC, output have +24v, +12V, +5V, and the +5V_stb in

standby state.

Keyboard module has 7 function keys (program increase/decrease, volume

increase/decrease, AV/TV switch, menu key, on/standby control), customer could use the

key of the machine to manipulate the LCD TV.

LCD screen has built-in inverter that convert DC into high voltage AC signal to ignite the

backlight CCFL (Cold Cathode Fluorescent Light); the LCD screen process the video signal

from signal board and reappear.

2. Image processing IC SVP-CX32LF

SVP-CX32 is a high integrated video decoding, image processing chip and is widely used in such

mainstream flat screen TVs as HDTV, PC, LCD TV, and Plasma TV etc. it inherited the technological advantage

of its earlier stage scaler chip. It adopts the 6th generation Trident multi-zooming mode and non-interlaced

scanning technology when processing image. Multi-color mode (PAL/SECAM/NTSC) decoding is built-in; 10bit

A/D module, 8bit LVDS transmission interface, digital comb filter module, and 3D digital comb video decoding
are available. Such functions as video enhancement, OSD and VBI/Closed Caption, and teletext（LEVEL 2.5）

are available. The function of the chip makes it adapt to global market. The decoder could operate under

PAL/SECAM/NTSC mode; there are such input interfaces as 5 channels CVBS, 2 channels chroma signal, 1
channel PC RGB, 2 channels YpbPr, and 8-bit Digital ITU-R656/601（HDMI interface）。

Its main features are:

● 6th generation image dynamic smooth filtering

● 10-bits A/D conversion

● PC automatic phase and mode recognition, white balance correction

● 8bits LVDS transmission interface

This chapter Mainly introduces the receiving and processing of image signal and sound signal, whole
machine system control process, and whole machine power supply system (Model of LT32GJ01E is taken as
an example, other models is similar and will not be explained here for each. There are minor differences in
power supply among different models of liquid crystal screen; the details are shown in Specifications).

1. Image signal flow

RF signal is demodulated by tuner, then the obtained video signal and signals inputted from COMPONENT
terminal, AV terminal, S terminal, 2-way Scart interface and VGA interface are all sent into video-processing IC
SVP-CX32LF to be processed. Input signals with different format are changed into uniform LVDS differential
signals, and are sent to liquid crystal screen. In addition, TV video signal is processed by SVP-CX32LF to
generate 2-way CVBS signal, which is used in 2-way Scart video output.

Signal inputted from HDMI interface is decoded into digital video signal, which is sent into video decoding IC
SVP-CX32LF to be processed. After procession, the obtained uniform LVDS differential signal is sent to liquid
crystal screen through LVDS interface to screen.

2.Sound flow

RF signal is demodulated by tuner, and then the obtained SIF signal (SIF-2 signal) and audio signal inputted
from Scart1 interface are directly processed by STV-8217. The output audio signal of STV-8217 is sent into
power amplifier TDA8944J, and the amplified signal is finally sent to speaker or earphone output.

Signals from HDTV terminal, AV terminal, Scart2 interface and PC Audio are first sent into 74HCT4052D for
choosing passages, and then sent into STV-8217 for demodulation and sound effect processing. The output
audio signal of STV-8217 is sent into power amplifier TDA8944J, and finally the amplified signals are sent to
speaker or earphone output.

After the demodulation and sound effect processing of STV-8217, there is an audio output which is used for
sound output of Scart1 terminal.

3. Whole machine power supply system

There are 4 ways of voltage output in the power panel: +24V（6A）、+12V（2A）、+5V（2A）and +5VS（1A）.
+24V output is used by LCD screen; +12V output is used by power amplifier TDA8944J, and is also changed
into +8V output by AZ78L08ZTR-E1 to satisfy the need of STV-8217 IC; +5V output is changed into 1.8V output
and 3.3V output by DO (such as AZ1117H-1.8TRE1 and AZ1117H-3.3TRE1) to satisfy the needs ICs. +24V,
+12V and +5V outputs will be cut off in standby state. While +5VS output is the power supply of MCU, infrared
receiver and EEPROM etc, and will be cut off when the AC is turn off.

5V output will be divided into two ways: one way is changed into +3.3V and +1.8V analogue power supplies
through DC/DC converter for STV-8217 IC, ANX9011LF IC etc and peripheral circuits; other way is changed
into +3.3V and +1.8V digital power supplies through DC/DC converter for SVP-CX32 IC etc and peripheral
circuits, and this way of 5V voltage will be cut off in standby state, while the other way of 5V voltage supply
power especially for MCU, infrared receiver and EEPROM etc, and will not be cut off in standby state.

1．Failure phenomenon：The picture is normal，but OSD has line in it.
The reason and the processing：Check the pin of U2 and pin 80-160 of U1 for pseudo

soldering, and have pseudo soldering touched up.

2．Failure phenomenon：There is sound but no picture; there is no OSD when start up; and

the back light is bright.
The reason and the processing：Check the connecting line to screen, and have it

connected well.

3．Failure phenomenon：There are no picture, no sound, and no snow flower dot in TV

mode, but AV is normal.
The reason and the processing：Check the tuner and its peripheral circuits (including bus

and power supply). If the peripheral circuits work well but there is no output from tuner,

then the tuner must be failure.

4．Failure phenomenon：LCD television cannot be controlled(including no starting up with

red light on, remote control and local key having no effect, etc).
The reason and the processing：LCD television has crash phenomenon, restart after

power off.

5．Failure phenomenon：+5V_SB voltage has output, but there are no picture, no sound,

and back light and indicating light are not on.
The reason and the processing：Check other groups of voltage; if they have no outputs,

then check Flash to find if it is installed well or damaged; if Flash is OK, find out that if the

power supply and output voltage of U4 works well.
