Hi, I have a Stern Flight 2000 with this board, on C16 somebody installed a jumper across the cap. If I remove the jumper the background sounds go away. I’ve recapped the board, same issue. Only way to bring the background sounds back is with that jumper wire installed. Do you have any ideas what could be wrong? Board is working fine except it has the “launch/take off” sound missing. Thankss!!!!
I’m horribly troubleshooting sounds. I am much better with digital than analog. Sorry I am not much help on this one. I would post on Pinside as there a few people that are sound experts.
No problem! I know this board is pretty hard to diagnose. Will follow your advise and post on pinside. Thanks
Can you pass along the link to Pinside? Curious to see what others say.
Sure, but I had no luck: https://pinside.com/pinball/forum/topic/stern-sb-300-pcb-cap-has-a-jumper-wire-across
Thanks for the link. Sorry it’s not getting my attention.
