So I am looking for a couple of things. I am hoping someone can post a picture of the cpu connections so I can compare it to mine.
A little background, the game was in pieces when I got it. Once I found some important parts I needed I started tinkering with it. I turned it on and got a green screen with a little bit of garbage on it. After checking voltages and re-seating connectors I found removing the wires in the picture would allow the game to play. I pulled this part of the connector and the game came on. I coined it up and both sides play as they should, but I do not have any sound.
The question is what are these wires (they go to the audio board) and why does removing them let the game play. Also, if I put the connector back on after playing the screen turns green again. Hope this made sense and I appreciate any help. Thanx in advance.

Oh, and I need the piece of metal that holds the glass in.
