Model No.: LCT-32CHSTP
Version: 1.0
PCB Assembly：
It is mainly composed of TV Board、Remote Control Receiver (Signal Receiver), K Board and Main
Board. Hereunder function introduction to every PCB Assembly:
No. Parts Description
1 Main Board
Assembly
It is the core of signal processing for LCD TV, which takes responsibility
of transforming outer signal into the uniform digital signal identified by
LCD display with use of System Control IC TV and AV signals input from
TV Board are decoded by UOCIII to transport RGB signal which is to be
transformed by TDA8759 modulus to transport 24bit RGB digital signal,
then it is to be transformed by GM1601/GM1501 to produce LVDS signal
displayed on the screen, in addition, signals input from VGA, DVI
would directly enter into GM1501 procedure, format transformation and
on screen display.
2 TV Board
Assembly
It is mainly composed of two tuners (main and sub tuners), AV/S, HD
signal terminals and some peripheral processing IC. The main tuner
demodulates RF signal to IF signal, and the sub tuner produces CVBS
signal, all signals are sent to the main board after transfer.
3 Remote Control
Receiver
Assembly
It is composed of one indicator light and one remote control receiver,
which enable Users operate the TV conveniently and know its current
working status simply with a remote control.
4 Built-in Power
Board Assembly
It can transform AC 220V into DC for ICs, including +24V, +12V, +5V
and +5VS power supply in standby mode.
5 K Board
Assembly
It consists of 7 function buttons by which users can operate the TV freely.
6 Screen Assembly Screens for LS08 have built-in adverse transformer, which change DC to
high voltage AC signal lightening the back light; The LCD screen is used
to display the image after the image signal has been processed by the
main board.
