SERVICE MANUAL LS07 chassis

The Constitute of the PCB is easier than LP03 chassis, all the Signal

Processing are in Main board.

1 Main board Module

Main board Module is the main part of Signal Processing in LCD TV. The input signal is Converted into uniform digital signal which can be Identified by LCM by system control circuit. Main board Module contain two parts of signal processing Module: Philips UOC3 process analog audio and videoo circuit mainly, MST518 process VGA circuit signal Format transform system control circuit mainly. the front module can convert the video IF signal and audio IF signal from tuner into RGB analog signal and audio signal, this part is named analog audio and video decoding process. The RGB color from UOC is received by MST518 and accomplish A/D convertion , output suitable digital color signal to Drive circuit of TFT . 8051 Processor inside UOC is responsible for co-operation the each part of works in system, and Respond to user operation which is operated on Control panel(key-press panel Module).

2 Key board Module

It is composed of 7 function keys. the user can operate the LCD TV conveniently by using this Module.

3 Remote control receiving board Module

It is composed of a work indicator light and a remote receive head. the user use the remote control box by this module can operate the LCD TV conveniently and know the LCD TV work condition.

4 Earphone output board module

It is composed of a earphone outlet, user can Listen to by earphone conveniently.

5 Inverter board module(include inverter circuit)

The function of the inverter is supply power to light tube in TFT , and lighten the back lamp Unit of TFT moldule, so the user can see the image on TFT.
