Hello all. I am new to this forum and new to working with electronics. I need whatever help you guys can give me. Ok to start i have done research on my screen and have come up with alot of info. first off will be the pdf's i have found.
chipset is vp77
and lcd is AT070tn01 v.2
well i would post them but i have not posted yet so it wont let me.
i managed to get the power for the backlight running but now i am working on wiring an s-video cable or composite rca cable up to this lcd so i can use it in a carputer. I have found what most of the wires i have do but not all of them. here is what it looks like for the pinout on the board
IGND (no wire)
VGH (Positive power for scan driver)
VEE (not sure)
VCC (Supply voltage for logic control circuit scan driver)
VDD (video digital input)
VIN (not sure, no wire)
VSS (needed for power)
GND (Ground)
NTPC (not sure)
CVBS (Composite video input 1)
AGND (i think another ground)
SDA (Serial I/F data in/out)
SCL (Serial I/F clock)
i cant figure out which lines would work for a s-video connection and i have already tried wiring to cvbs up to a rca cable but still no picture. any help you guys can give me would be wonderful and if anything i have typed is wrong let me know. I can add pictures of the lcd and board if need be. thanks ahead of time
