I was playing the other day, and just in a middle of a normal game, the knocker went off in the cab, and all the flippers went dead...
The music and GI (and maybe the insert, im not really sure), still worked...
I turned off the machine rather quickly, and basically didnt have time to check more that day.

The next day i checked the fuses, and all are ok.
I turned it on again, and the only thing working is the GI. No display, or anything...

I opened the coin door and opened it, and i get the gi, and a beep beep beep contiuous from the speaker...

What did i mess up, and where do I start to look? Any tips a appreciated

Could my roms have rotted after all these years?
Will something like this be probable to happen?
I have ordered a rom burner for other reasons, but i will update the roms in my machines while im at it, just hoping the roms are bad, that would be an easy fix, no fuses are blown

yeah, ill do that.
Thanks for the tips ppl
