Hello everyone, I've been lurking here for a while but this is my first post I think... I've restored a machine before (Jump Bug by Rock-Ola, mostly cosmetic restoration) but this is the first time I've done any real troubleshooting.
I've got a Qbert with two main issues. First, the video is messed up; the image starts at the middle and the bottom half of the image shows up at the top; other parts of the image look a bit garbled as well (these pictures are lousy but you get the idea):
The monitor is also flickering but that's probably a better question for the monitor forum.
Also, there is no sound; it says "I am turned on" when powered up but is silent thereafter. When the test button on the sound board is pressed, there's a single tone that plays for a few seconds and nothing else.
So far, I've reseated all the chips on all the boards and checked all connections... what's the next step? Thanks for any help!
