    When you connect up the DC pack, the screen should (just) visibly become a little darker.

    You'll need to apply 5V to the power on pin to switch the backlit on.

    You should check Starfox website for which pin is which. There is a little TTL circuit that I draw which have all pin needed for VGA modded.
    Search for TTL circuit on this forum. Like starfox said, you need to apply 5V to pin 10 (I think) to the AV connector of the PSOne LCD to turn the backlit on.
