PCB function
1. Power:
(1). Input voltage: AC 100V~240V, 47Hz~63Hz.
Input range: AC 90V(Min)~264V(Max) auto regulation.
(2). To provide power for PCBs.
a). +24V for Inverter.
b). +5Vsb for standby,
c). +5V for signal power,
d). +18V for Audio Amp power and converter to +12V for Lvds power.
2. Main (Video InterFace) board:
(1).Decoder the video signal (TV,CVBS,S-VIDEO,YCbCr) from analog to digital
signal.
(2).Converter the Video signals( TV,CVBS,S-VIDEO,YCbCr) and graphics signal
(DVI,VGA,YPbPr) from internace to progressive,
(3). Converter the Digital to fit the panel display mode and output the LVDS
signal to Panel.
3. Tuner Board:
Convert TV RF signal to video and audio signal to Main board.
4. Audio board:
(1).Decoder the TV SIF signal to audio signal,
(2).Converter the audio to audio Ampifile and out put to the external speaker.
(3).3D comb-filter
5. KEYBOARD
To get the main button control on LCD_TV as SOURCE,MENU,
CHANEL +,CHANEL -, VOL +,VOL-, STANDBY functions.
6. Remote control board
Receive the remote signal and active for the control.
7. T-CONTROL board
Converter the LVDS signal to the digital signal for fitting the PANEL.
8. INVERTER board
Converter the low DC voltage +24V to high AC voltage about AC600V to drive
the backlight.
