Armed Police Batrider PCB - no graphics / no sound

Critical Damage!,
Greetings,

I've got a Batrider PCB - relatively decent shape, a tad dirty, but no obvious repairs or replaced chips, etc:

Spoiler:

Response on supergun and multiple cabs is the same.
- No video
- It is receiving power
- Sound starts and immediately crashes
- Touching the sound chip while on will create buzzing sound, but game sound doesn't kick back in

What i've done:
- Reseated all roms, cleaned their legs
- Cleaned the JAMMA connector
- Yelled at the PCB

Any known issues with this particular board? Any other things I can do before selling it as is or sending out for possible repair?
