After two years of running in an arcade, my Dig Dug boots up to a gray screen. I couldn't find anything online for this issue. Anyone have a suggestion for what to check or know what would have caused this?
 
Basics

Have you tested or checked anything? Break out a multi meter and start looking at voltages on the pcb.. Then check the ARII pcb..

If your ARII needs help, I can rebuild it or sell you a rebuilt and working one..
 
Stop...

1) Does it play blind...

2) If yes, does it have a 4600 in it?

3) If yes, replace the zener and 1 transistor in the blanking circuit

I had a Kangaroo that did that.
