I have an Atari C-380 Video Pinball console. The system seems to work fine, except there is no sound. This unit has an internal speaker (does not use the TV for sound.) I thought maybe I had a bad speaker, but tried another speaker and still no sound whatsoever... no static, no clicks, nothing. I have checked for cold solder joints and such, but have not the problem.
Does anyone have any suggestions? Thank you.
