Last week I picked up a Ms Pac from bigdaddynsir, and I think the bumpy ride home may have done some damage - it was playing blind before I got it home, but when I got it unloaded, the pcb had worked it's way out of the plastic holders that it slides into, and was hanging by the edge connector. I checked everything out, reseated the connector and mounted the board correctly, plugged it in and all I get is a loud feedback noise from the speaker, and it blows both 7A fuses. The sound is continuous even after the fuses blow. Any ideas on where I should start?
