LCD TV with LS01 is made up of power board, side AV board, remote control reception
board, key board, and mainboard. The table below is the introduction of the function of all
printed board modules.
No. Parts Description
Mainboard module is the core 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.

The remote reception board module is constituted by an indicator-light and a
remote reception. 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 judged (red is standby, green is power on).
Convert the 100V～240V （50/60HZ）AC into DC, output have +24v, +12V,
+5V, and the +5V_STB in standby state.
Keyboard module has 7 function keys (program +/-, volume +/-, AV/TV,
menu ,power), customer could use the key to operate the TV freely.
LCD screen has built-in inverter that convert DC into high voltage AC signal to
turn on the backlight CCFL (Cold Cathode Fluorescent Light); the LCD screen
process the video signal from signal board and reappear.
Side AV board is used for earphone output.

Chapter 3: Analysis of Signal process Flowchart and key point
,
measure date
This chapter mainly introduces the receipt and dispose of AV signal the power supply
system and system control process of this TV. (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 LCD screen; the details are shown in Specifications).
1. Video signal flow
RF signal is demodulated by tuner, then the obtained video signal and signals inputted from
COMPONENT terminal, AV, S-VIDEO, 2-way SCART interface and VGA interface are all sent
into video-processing IC SVP-CX32LF for decoding. The different format input signals are
changed into uniform LVDS signals, and are sent to LCD screen. In addition, TV video signal is
processed by SVP-CX32LF to generate 2 CVBS signal, which are used in SCART video output.
Signal inputted from HDMI interface is decoded into digital video signal BY ANX9011L,
which is sent into video decoding IC SVP-CX32LF for decoding. After procession, the obtained
uniform LVDS differential signal is sent into LCD Screen.
2.Sound process 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 into speaker or earphone.
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
process. The output audio signal of STV-8217 is sent into power amplifier TDA8944J, and
finally the amplified signals are sent into speaker or earphone.
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. 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 provided for LCD screen; +12V output is provided for power
amplifier TDA8944J, and is also changed into +8V output by AZ78L08ZTR-E1 to supply
STV-8217 IC; +5V output is changed into 1.8V output and 3.3V output by DC/DC (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 still operating in standby state.
