Hello!

New here. I've had this machine for many years. It has always worked fine. I hit a jackpot and didn't have enough tokens in it to payout. I opened it and tried too reset it but to no avail. I've reset it before, but can't seem to do it this time. It just displays a "1" on the front "Count" display. I've read many manuals about how to reset similar machines, but no luck. Any ideas?
