The TV system block diagram is powered by power board that transforms AC source
of 100V~240V AC +/- 10% @ 50/60 HZ into DC 5V & 12V& 24Vsource. The main
board receives different types of video signal into the MT5372 Ic. Afterward, the
MT5372 Ic process the signals control the various functions of the monitor and
outputs control signal, video signal and power to the 32” WXGA panel to be displayed.
The power send to the panel is first processed by the inverter. The function of the
inverter is to step up the voltage supplied by the main board to the power that is
needed to light up the lamps in the panel. Simultaneously, the digital video signals are
processed in the panel and the outcome determines the brightness, pixel on/off and
the color displayed on the panel. The analog video signals of S-video, YPbPr, TV, PC
and A/V all video signals are translated from analog signals into MT5372 generates
the vertical and horizontal timing signals for display device. The analog audio of
s-video, YpbPr, TV, PC and A/V is transmitting to the WM8776 processed. The
purpose is process the input audio signal to control volume, bass, treble, surround,
and balance. All functions are controllable by the main board. Plus, all functions in the
IC boards are programmable using I2C Bus.
