Playstation LCD Hack - Works!!
Friend dropped by today and tested out some stuff on my Sony PSOne LCD, and we pulled this one off (more like he pulled it off while i was making a composite -> 3.5mm cable).
My PSOne LCD is a PAL LCD. There *is* a difference between the NTSC and PAL LCDs, the timings are not in powerstrip for the PAL Sony PSOne LCD. We obtained approximate timings from http://www.hut.fi/Misc/Electronics/c...nversion.html.

But it works!!! It f***ing works!!! :)
Video card: Radeon 9000 Pro, on Dual Monitor mode (else there was no way we could try the PAL timings without rebooting every time).
We found after comparing the Sony MultiAV passthrough with the input that only the SVideo Y, R, G and B lines are not directly passed through. The Video CSync pin on the MultiAV connector (pin 6) actually went straight through, which made us wonder if it was the correct pin.
Some of the wiring diagrams available on the web are slightly misleading:
Wire the +5V line (pin 10) to the VGA DCC to obtain 5V. When the LCD senses +5V on the +5V line, it switches on. This is some sort of sense line.
Wire VGA CSync to pin 5 (SVideo Y). This is *NOT* the same as Composite / CSync on the Sony MultiAV out.
Tell your video card to use composite sync! This hack doesn't need a resistor between VSync and HSync as it's using CSync, which is done on the video card.
Nb. Please do not try the above just yet, i'll review everything with my friend and post everything up on a website. Also note that this has only been tested on the PAL LCD, and we can't test it on a NTSC display.
