GI JOE Sound

[NerdyBros]

I’m truly sorry if this is a dumb question, but I just picked up a GI JOE PCB that looks in phenomenal shape, but I’m getting no sound. I noticed the board has a sound out section, do I not get sound though JAMMA with this one? Do I need an extra audio harness? None of my other boards has an audio out section (I think) so it might be just something I’m not familiar with. Thank you in advance.

edit: been getting sporadic audio if I apply pressure on the audio module. Must be going out. Mods feel free to delete this, my bad.

desolder and recap the hybrid sound module

Thank you Drago. I did learn since then how those go bad fairly often. Got a new module from Caius, one of the crystals was also lifted for whatever reason. It was a bit more advanced repair than I can handle so worked with Ken at irepairsega. Awesome dude.
