First of, sorry for replying in an old threat, but i was doubting between opening a new one and/or continueing an existing one.
Hey, I've got one of those screens too.
The mentioned link shows "Information: You are not authorised to access this area." so the power story i can't seem to access.
Question though how did you guys connect the screen?
Resolder some wires?
Or is it possible to use the output (and the original PS1 cable) to connect to the RCA connector??
(output-output doesn't sound logic, but there's a topic i found via google that said (most) of the connectors in the in/output are hardwired.

found more specifics on wiring, but i'm kinda lost.
