I just purchased a Flight 2K. Playtested and thoroughly inspected the game at sellers and all was well.
Moved home, carefully reconnected everything and now I have speech, but no game sound (although there are times, game over for example, when there is a white noise). Any ideas or suggestions would be greatly appreciated. I reseated connectors, checked and double checked all were installed properly and in the correct location, but I failed to get great photos of the SB300 connectors before I left, so there is a remote possibility that something isn't right in that regard. Most are keyed, so it is pretty straight forward. It has an Alltek MPU and LED lamp driver. Game plays just fine, with the exception of the sound issue.
Excuse my ignorance, but I have searched extensively and I can't find much info about troubleshooting this issue and scarce info about even a sound test on classic sterns. This is my first classic Stern, but I am somewhat familiar with classic ballys. I am not incredibly knowledgeable about troubleshooting with a multimeter, although I have one. On classic Ballys I would hit the sound test button but there doesn't seem to be one located anywhere.
