Hey guys,
Looking for some possible things to try to fix this. Probably will just buy a replacement PCB but figure it's worth a try.
My MK 1 lost its sound. It's a rev 5.0 T-unit setup with the separate sound PCB (From memory, I'm thinking the earlier boards didn't use a separate sound PCB).
Game plays fine, and the sound test gives an Interrupt Test success message, but no sound is played. My assumption is something is wrong on the sound PCB, though I suppose it might be the main PCB. No other symptoms, just dead sound.
I tried reseating the chips, no change. That's about the limit of my troubleshooting ability, without more guidance.
Any tips? Or just buy a new boardset? (If you have a known good boardset or very nice original MK marquee, please let me know.)
Thanks!
