    The 9800Pro still has a hardware dip-switch on the PCB to switch between NTSC and PAL (per default it is set to NTSC). However I find that with the ATi Catalyst drivers you can simply switch between NTSC and PAL from the desktop, regardless of the position of this switch. So yes, PAL screens will work perfectly fine on a US Radeon 9800.

    can someone lemme know what the specs on the power adapter for a official ps1 screen? i bought a wall adapter that goes to 7.5v(which i know i need) but only has 300mA of power. is this enough to run the screen? when i turn it on it flashes on for a second then goes blank, even when i have the screen plugged into my ps2 to test it.

    I'm doing this mod right now and I am at the stage where I need to connect this thing to a VGA cable. I have got hold of an old cable with all the pins, but some of the wires are missing so its useless. Would it be possible to actually solder the wires from the LCD to one end of a double male ended vga cable?

    7.5v 3000mA (3 amps). Classic brown out symptoms there, get a real one and it'll work fine.

    Yes it would :D

    That's how I did mine, no parts of the PS cable, just leads straight from the screen to the graphics card (hardwired onto the back, but a VGA connecter would work just as well.)

    Theres another question, how long have the colours of the wires inside the VGA cable been standard for? Because in the cable I cut up, the wire colours were completely different to the ones specified in the guide.

    What if I can't find a cable with the DCC pin? Is the DCC completely necessary for PAL screens?

    Find the wiring out using a voltmeter, it's the only way to be sure. The DCC pin is neccecary to activate the screen, but can be taken directly off of the PCB itself. You just need to figure out which wire it goes to and then solder it onto the board.

    Shown is my screen with the DCC pin directly on the PCB.

    I have the same LCD as you, so which wire did you solder onto the PCB?

    Looking at the picture, there are two connectors to the screen. It is the wire on the very left of the right connector, roughly here:

    And that is connected directly to the PCB?

    Thanks! And sorry for the so many questions, I don't want to make a mistake and fry the thing or something!

    Now I'm just waiting for my car adaptor to arrive on monday...

    if im not mistaken, you need 1 o 2 A for the backlight to switch (and stay .p) on.

    the one that 3a 7,5v is for powering the lcd + ps one console.

    Probably not, I've only seen touch screen covers that range from 15-21" monitors. I think the only thing you'll find is a small lcd with built in touch screen.
