HI All,
Got a new pin yesterday, a Williams Big Guns. All was working fine, startup, switch test etc. Today on firing it up it is stuck in the adjustments menu. No pressing of coin door buttons seems to do anything. Game boots, and the ADJ menu scrolls furiously past on the displays, then resets.
Occasionally it will start into the music test mode, in which the start button works to scroll through music test choices.
I have checked connectors and all are secure.
CPU LED status lights are normal.
Coin door adjustment button presses do not register

Game starts up and continually cycles through the adjustments menu without anything being touched. Disconnecting the coin door wiring has no effect on the startup. I have tried power cycling with memory batteries removed etc. Any assistance is appreciated.

Should be in alphanumeric subforum. Please move.

Disconnecting switch matrix plugs on cpu board have no effect. Starting up with coin door switches disconnected launches into music test function that can not be exited.
