Sega ST-V Board Missing Right Channel Audio

Hey guys,

I've got an ST-V board that will not output right channel audio. In the test menu, I get a 'beep <silence> beep' on the left/right/stereo test whereas on my working board I get the full three beeps. I have tried both audio over JAMMA (really mono, but it combines the left/right channels on my working board) as well as the stereo connector.

Anyone have an idea of what could cause this and what the most likely issue is?

I've got another broken board that I can part swap the relevant chips/components from if needed.

Thanks for any help you can provide!

Most likely a bad cap, just recap the sound section, it needs it anyway being this old now.
