    Shouldn't have to do with the DVI connector, as i used that on mine.

    Try grounding VGA Pin 11. If it still doesn't work after that, ground VGA pin 4 as well.

    arrrggghhhhhhhh!!!! :-(

    Tried grounding pins 11 and 4.......
    extending desktop to the display still wont take. Just greys back out after trying to apply. Screen is powered on too when I try.
    I've checked my soldering with a curcuit tester and this is how it currently stands.

    vga1(red)-psx11
    vga2(grn)-psx12
    vga3(blu)-psx9

    vga9-(+5v)-psx10
    vga13-(sync)-psx5

    vga4-(gnd)-psx8
    vga5-(gnd)-psx8
    vga6-(gnd)-psx8
    vga7-(gnd)-psx8
    vga8-(gnd)-psx8
    vga10-(gnd)-psx8
    vga11-(gnd)-psx8

    vga12- not connected
    vga14- not connected
    vga15- not connected

    Its gonna be hard soldering anymore cables in there with the shovel of a soldering iron Ive got!

    Pins12(id1 or sda) and pin15(id3 or scl) - whats sda and csl stand for? do I need them connected up too!?

    any more ideas.........before I sell the damn thing!

    Isn't there a 'force detection of secondary display' setting in the Radeon control panel?

    Can you try plug in a second monitor to the secondary just to get the Radeon to detect a monitor, then unplug the second monitor and plug the LCD in. See if that displays anything?

    The PS1 LCds... are they 5.6" screens?

    If so this hack + a pair of $8 shroud / mounting kits from Parts Express. And I'll have VGA headrest monitors!

    So... are they 5.6"? I'm going to be REALLY HAPPY if they are!

    Also.. are the PS1 / PS2 screens the same, or does anyone know?

    Mine's 13cm diagonal, so that's about 5.1".

    The PCB on the back though is a little larger than the actual LCD, dont' forget to take that into account..

    Just remember that this isn't a standard VGA, so you won't see anything until Powerstrip / X initialises.

    Hi everyone,

    I have one of these PSOne LCD screens as well and I plan to install it into my dash. I've had a skim through this thread and notice everyone talking of wiring layouts and such. I was wondering what you were wiring up exactly ?

    I have this screen working on my laptop at the moment using just the normal power convertor (which I will replace with a cigarette lighter Dc-DC adapter in the car) and a headphone->composite adapter where the headphone jack has 4 segments instead of the normal three (this cable is available from Harvey Norman in Australia). Composite plugs into a VGA->Composite converter.

    This setup works fine driven by X-Windows on my soon-to-be-incar-laptop.

    Hope you can clear up what im missing here !

    S.
