Ive got an Atari tetris board, it worked fine, then one day lost sound. Tried it in a few different cabinets and all had no sound, so its a board problem.... anybody know what the fix is?
 
Forgive me if you did this already, but have you tried adjusting the volume pot on the pcb? If it has some corrosion or a loose solder joint the audio could be cutting out.

I went to the vaps page to look at the schematics to see if it takes -5 for sound. It does not. I would second the volumn pot adjustment. It could get corroded. Any ways, look at the poor conversions of this game on VAPS. Oh the horror.

Not sure if that has the MB3730 amp chip on it (long skinny chip) but if so its possible the speaker wires got shorted or something and killed the chip. Bob Roberts and other places like electronix.com sells them.
