Function Description
Main Board 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 。 After RF signal
processed by tuner, It was sent to the main chip (analog signal was
sent to MSD116 for processing ,and digital signal was sent to
MSD809 for decoding first and then to MSD116 for processing ),
then the main chip(MSD116 ) produce LVDS signal displayed on
the screen .In addition, signals input from VGA、AV、SVIDEO and
YPbPr would directly enter into MSD116 for processing, format
transformation and on screen display. HDMI signal was sent to
MST3383 for processing first and then transmitted to MSD116 for
processing, format transformation and on screen display. And there
is a headphone output interface near the tuner. For LS16 only, it
has a digital audio output interface(SPDIF).
It is composite of one light indicator and one remote control
receiver, which enable users operate the TV conveniently and
know its current working status simply with a remote control.
It can transform AC power into DC for ICs including+12V，+5V and
ADJ for switching the backlight of LCD on or off and adjusting the
brightness.
It consists of 7 function buttons by which users can operate the TV
freely.
The LCD screen is used to display the image after the image signal
has been processed by the main board.
