Hey guys. I have a Ms. Pac-Man that sat in storage for several years. After I pulled it out and brought it to my house, the sound stopped working after about 30 minutes of play. This happened some time ago, and I've just been too busy to deal with it. Other than the lack of sound, it's continued to work fine.
There is a constant hum once the machine is powered on. The hum will change in volume if I adjust the pot. Running my finger across the pins of the lm377 amp results in static, so I think it should be good. I've cleaned and reseated the edge connector.
Any ideas? Based on what I've read I think my next step is to start replacing caps in the sound area, but I wanted to ask folks with far more experience than I have.
