Got an Asteroids that sat for a while, was fixed, then stopped working. Buttons don't flash (it's on free play) and and it makes a loud humming noise. Flipping the test switch makes not much difference, although the start buttons flicker sporadically and sometimes I get something on the screen like a diagonal line.

I've already verified the monitor works, and have swapped in working AR1 and Main PCB's with no change.

I guess my next step is to replace the Big Blue?
 
When mine did this it was the big blue. I had changed it but one of the wires came loose and I had these symptoms.

I did have an Asteroids doing something similar and a big blue fixed it.

Good to know. Just got one in from Bob, so I'll replace it and see what happens...
 
Keep us posted. My vote is with BB as well, I've seen it cause this exact issue.
