Hey guys.
Picked up a Ms. Pac that isn't working. When I plug it in (previous owner has bypassed the power switch) I immediately get a garbage screen (non-moving) and that's it. I also have a loud buzz in the speaker.
Here's what it looks like every time:

I've cleaned the edge connector and re-seated the ROMs. I've also bypassed the daughter board and am getting the exact same result.
Found another thread that suggested replacing the fuse block right away. I've done that and am still getting the same thing.
I am no whizz at troubleshooting boards. Has anyone seen this same screen? It doesn't match anything I am seeing on the troubleshooting screenshot gallery. Any help getting me pointed in the right direction would be appreciated.
