OK, i have the Pyle PLVH72,
it is a 7.2" LCD where there are two RCA inputs, and 12vdc....
I want to connect it directly to a RGB (VGA) input, without touching the RCA.
so i opened it. i saw two boards - one of them is the interface board, and the another one is the lcd inverter (not only for CCFL)....
on the lcd board it is written:
Sharp QPWBS1017CPZZ
G4GB V
on the interface board there is written:
SM72SD1NR
030710
For SM7200
(should be the name of the LCD)
I think the interface board where all the buttons are, is receiving RCA (PAL+NTSC) signals (for sure) and converting them into RGB to the LCD....
[didnt find help anywhere]
on the right - it is the interface board, with all commands and all that....
i think it converts the RCA input to RGB, and then sends it to the left board - the lcd inverter.
a wide ribbon cable from the module itself to the inverter (30 pins)
The only wires between the interface board - where is the input and the lcd inverter. -
signals MUST pass here...
the nearest chip to the 30 pins from module...
left is the input, where comes the two RCA inputs and the +12Vdc
behind the 10 wires connecting the interface board and the inverter - maybe another type of connection
as i said, the 10 wires are the only to connect the two boards - the right one is for the buttons...
Please help,
Avner
