Is it possible for a sound chip in an MVS game to blow?

I was playing my SHOCK TROOPERS twenty minutes ago and during the game there was a "Pop" sound, kind of like those thing you throw on the ground. After the sound my CMVS reset the game, and when it did the sound was slightly garbled. I took it out, re-slotted it and it didn't do that anymore, but their was some kind of hum sound in the background.

Decided to power up on my 2-Slot upright Cab, and the game doesn't do that, but the music seems a bit off now, like it's on a low volume setting even if it's on full blast??? Has anyone ever had something like this happen, and is it a sound chip in the game itself?

You may have blown a fuse or capacitor inside the cabinet and that could've messed with the voltages, making the sound screwy.

The chip couldn't really "blow", and if it did, it would immediately stop processing sound data.

Check the fuses, capacitors and your transformer inside the cab.. you'll probably see a black scorch on one of them.

Thanks for the reply Vanilla.... It seems it's my CMVS unit. When I slot the game in either slot on the upright 2-Slot it works fine, but for some reason my CMVS is either resetting the game all together 3 minutes into the game, or it plays but with odd sound distortions??? Between that and always being told every other game needs a Cross Hatch Test I've just about had it with the CMVS, damn glad I didn't sell my upright after all.

Check the 12 volt supply to the mobo, the 12 volts supplies nothing but the audio output circuitry, so if lets say an electrolytic 12 volt smoothing cap in the psu went "pop" (as is their want at times), resulting in a low 12 volts, the result may be distorted sound. No 12 volts = no sound.

Ah, thanks for the advice I'll have to check that now. :smirk:
