I have a Road Kings that I maintain here at work that people get a kick out of playing. Someone let me know that during a game they were playing, everything shut off except the music. The flippers died, the lights and displays went off and the only thing that was working was the music.

Turning the machine off and back on seemed to fix it, but when I go into audit mode, the audit stats appear to be gibberish numbers, and the lower-left display reads ERROR. Was there some kind of garbage data that made its way into the battery-powered memory that I need to somehow purge?
