Hi all, I recently picked up a Hiphopmania Complete Mix 2 Arcade and I can't seem to figure out what's wrong with the audio and I can't find a lot of info online for it. I hope someone has any insight on how to troubleshoot the issue.
The game plays properly and there's no diagnostics issues at all. The amplifier and speakers are good, I connected some other input and verified they work fine. This leads me to believe the PCB isn't producing the sound but I can't find any info on this Konami GQ753 board (attached pictures) or diagram. When I go into the game and play I can hear a faint sound that almost resembles the drum but it's very faint to discern. If there's anything y'all can suggest or docs to reference I would greatly appreciate it and thank you in advance!
The only other issue is a very loud buzzing from the monitor, I think maybe the flyback. But I don't think they would be correlated.

I might or might not have found the culprit on the board, see other photo.
