In your fist pic, underneath the ribbon cable and in between your red and black wire is a a little tuning knob, have you played with that yet? I had to tune that to get pic on my screen.

The project I'm looking to do next is to mod a PS1 to get a flip up screen by opening the disc drive. Just an idea I wanted to share.

@kitsch-bent I'd be in for 2 as well.
