My donkey kong does not have any audio. The game worked great for a while but then this problem came little by little as the audio quality got worse and worse. It took a few days for it to completely go out but now there is nothing at all.
I've read a lot of articles and most seem to suggest that if the problem is on the game board itself, it will typically be EITHER sound effects OR sound not working, but typically not both since they're independent. Is this correct?
Just wondering because I'm really unsure where to start, whether with the game board or the amplifier board at the monitor.
I have reseated the 8035 chip and verified continuity on all legs as well as the two audio rom chips with no change. If the 8035 were to fail would it kill all audio or just the music?
Also does anyone know what the voltages are supposed to be coming from the main monitor board to the amplifier board? I'm getting something like 108, and 130 or something like that (cant quite remember). Thanks for the help.
