I've read a few repair threads which mention replacing a Z80. Wasn't sure if there was a different issue going on with mine as the voice sound effects, such as "power up," "rise from your grave" etc and punch and kick sounds work. Just no background music at all.

Thanks for your thoughts.

Managed to come across this thread: https://forums.arcade-museum.com/showthread.php?t=90344

So maybe I do need a Z80B and a reprogrammed chip burned to overcome a battery suicide issue.

If your board is still running the battery z80 module for sound then yes reprogram the required eproms and replace with a z80B would be my first step
 
Correct me if I'm wrong, but if the sound effects are still working, wouldn't that mean the Z80 is still alive?

No harm in de-suiciding it I suppose.
