Hi all. I've had my FBC for a few years. It's the 2nd pin I ever bought and it's going nowhere. Absolutely love it.
That said, I have periodically had some sound issues, more often than not it's been with the backgound sound only. It's completely gone while the playfield sound effects work find. I just purchased one of the weebly cheap squeak replacements boards (which looks fantastic), but that didn't fix it. Same issue.
Any pointers?
