    Different video card that can be adjusted down to 15kHz (best option) or scan converter (poorer quality).

    I don't have a PSone LCD, never have, and have never attempted to connect one of these things. My familiarity is based on common sense on how this stuff actually works.

    Try a video card that supports the 15khz frequency and try wiring it to the standards of a VGA adapter.

    Just thought I would add my .02!

    I think that anyone who has gotten this to work and is very comfortable with this, should make more and sell them. I'm sure that dumb people like me that don't even wanna screw with modding a screen, would pay to just have it arrive at their house already modded.

    Again, just my .02

    Peace,

    No I didn't, I said they were "poorer" quality (than a video card running at 15kHz).

    Yep, it's a scan converter, it's probably a very nice scan converter. My advice is spend your money on a card that'll do 15kHz instead, you'll probably be happier with the result.

    This Link under TTL level sync signal show you how.

    Or you can look at my Express PCB drawing.
    I don't get part of this circuit.
    I colored the area in white that doesn't seem to make any sense to me. It seems that nothing is connected to 5 and 6 or the connection to the 78LS86 right next to them. Can someone explain what gets connected there?

    Jumper the middle pin to one of the outside pins. It's there to configure which psone connector pin is used to supply the csync.
