Hey everybody. Hoping somebody can help with this hopefully minor issue with my DBZ PCB.
When there is supposed to be no sound at all (test menu, certain parts of demo), I hear static/interference noise, and it amplifies when the screen is changing to something else (as in from the Banpresto logo to the title screen). If I listen very closely to the in-game music, I think I can hear a faint underlying static. The volume of this noise corresponds to volume level set by the sound pot on the PCB.
Some sounds effects seem a fair amount louder than others, but I'm not sure if that is part of the problem or just how the game was programmed.
When I run my finger under the chips in the sound area on the solder side, the interference changes and amplifies.
Beyond that, there are no other problems and all music/sounds seem to be present and without corruption.
I've blown the pot with condensed air and given it several turns - no help.
Thanks in advance
