So I have finally got some time to start repair on some of my games and Asteroids was first up.
The machine as I got it played almost blind, it did display a boomerang shaped object in the lower left hand corner. I tested a known working PCB and A/R in the cab and got a correct disply, but only in the left left corner. I recapped the PCB, the A/R and both monitor boards (G05-802). Now my boards work and the display is on the left half of the screen, not just lower left.
I have seen this issue reported in one of the trouble shooting guides when I was searching through them, but now I can't find it again. I have an good repair guide, but I do remember seeing this specific issue in one of them. Where can I go from here??
Thanks,
Aaron
