Last week, while playing a game of Medieval Madness, the sound suddenly shut off while gameplay continued. Then the initial "BONG!" sound effect from when you turn on the machine went off and then the sound and music came back on VERY LOUD (the default setting of 4 or 5? I have it set to 1 since it's in my kitchen).
The loud sound continued through the rest of the ball, but after tho bonus was tallied and ball two was placed into the shooter lane, the sound reset to its normal levels (??!). On ball two the same thing happened, only this time there was no music when it was really loud, only sound effects.
I've done a few more tests and it seems like this happens when I start a part of the game with new music (Royal Madness, Castle Multiball, etc.) On my latest test, I pushed through to ball 3 and the whole machine reset itself (GULP!)
I opened up the backbox and checked out the A/V board (if you can't tell - I don't know anything about this stuff) nothing looked visibly burned, all the fuses were OK, the LED was blinking the way its supposed to (according to the manual) so I'm not sure what's going on.
If anyone has any suggestions on what to check or anything to try, I would greatly appreciate it, thanks!
