Gorf has been my problem child since I got it...never had a game that is this finicky...
Anyway, Was having some intermittent lock ups, so I figured I would check all connections, reseat the boards, etc. Did this, game came back up, worked wonderfully, no more lock ups....BUT....
I have lost the audio on Channel 1.....I have no voice sounds or missile firing sounds. I just have all of the other sounds on both speakers. Did a check of all known fuses, voltages, etc....no dice.
Swapped out transistors, resistors, potentiometers from channel 1 to channel 2 and vice versa (did this one pair of items at a time). The problem never moved from one channel to the other. Checked the speaker wiring, everything looks good there.
Reseated everything, checked connections again, and fired it back up. For about 20 seconds, I had very faint voice and missile sounds then it went away.
I have no idea what else to check. I would be open to purchasing a known working stereo audio board to see if something that I didn't check in the board is fried (and to have a spare), but where else might I look? Since I didn't lose just the voice, I don't think it is the voice chip but I'm not sure.
Any help or guidance is much appreciated.
