I am noticing a loud background noise from my Mr. & Mrs. Pac-Man pinball. The problem seems to be somewhere in the Squawk & Talk PCB. Tried the MPU in another game and it checks out. The S&T also seems to have a jumper wire attached near the heat sink, looks like someones "attempt" at this repair. I can attach this jumper to ground and the background static will go away, but then after a few seconds I get no sound at all. I don't see any bad solder joints or cracks, I did replace the pots with no success, and I have reseated all chips. Also if the static gets worse at times, the displays go crazy.
Anyone have any idea what might be causing this? Caps maybe?
