PCB function
1. Power:
(1). Input voltage: AC 100V~120V, 45Hz~60Hz.
Input range: AC 90V(Min)~265V(Max) auto regulation.
(2). To provide power for PCBs.
2. Main (Video InterFace) board: To converter TV signals, S signals, AV signals, Y Pb/
Cb Pr/Cr signals, DVI signals and D-SUB signals to digital ones and to transmit to
Control board.
3. Control board: Dealing with the digital signal for output to panel.
4. Y-Sustainer / Z-Sustainer board:
(1). Receiving the signals from Control and high voltage supply.
(2). Output scanning waveform for Module.
5. Y-Drive board: Receive signal from Y sustainer, output horizontal scanning wave-
form to the panel.
6. X extension board (6pcs): Output addressing signals.
7. Tuner/Audio Board
: : : : :
Process and Amplifying the audio signal to speakers and
