Ms. Pacman... fails to boot fully, has weird graphics issue.
Ok, so I just bought a Ms. Pacman that I knew had some issues, but I have no experience with board repair and would love some pointers on a) what could be causing this issue and b) either a course of action to repair it myself or a reference to someone who is good at doing so. I don't mind buying tools to work on it myself as long as it's not something that will require more monetary investment than a board would cost... especially if it's something simple.
Now, having said that... here's the issue I'm facing. When I turn the machine on the marquee lights up and the monitor comes on and I get partial graphics on the screen (see pic #1), however the board never displays a self-test and there's no sound output aside from a humming that I assume is from the marquee lights or monitor. Now, the harness has been hacked a bit (see pic #2) and the edge connector has been "repaired" by jumpering from the harness to the trace on the board. I have also noticed that the diodes at D7 and D8 have either been reflowed or replaced at some point.
Could any of this be causing the issue at hand?
Thanks in advance guys.
