I have had this machine for some time and it’s always worked.

Now suddenly it will credit and start spinning the reels but none of the three buttons to stop work. Eventually the game will time out and the reels will stop.

So far I have tried a reset which worked fine. Also checked for 5VDC at the optical switches at the skill stop and there is power there.

I’m thinking a circuit issue? Does anyone know what could be wrong? Capacitor somewhere on one of the boards?

Thanks in advance for any help!!
