Need help with Gorf

and yes.... you're missing Green so that's likely:
  • bad chip on RGB board (small board between cage and monitor)
  • bad connector or wire to monitor
  • monitor issue
  • bad transistor on PCB stack
I'd connect a TPG (or another game) to that monitor and confirm it's not a monitor issue first. If not, it's likely the RGB board or connector between RGB board and the monitor chassis.
what about that TBA 530 chip? I had one of those go bad but it made the screen effectively inverted lol

also I believe we got a replacement from APAR so they're not unobtanium yet

There is only one chip on the RGB board (the TBA530), so when I called out "bad chip on RGB board" that's what I was referring to.

I buy a lot from Peter, but you can get the TBA530 from TwistWrist for 60% of what APAR charges, that link here.

you're a good citizen. I'm a @Riptor fan too
 
That did it. I cut the line for the test switch and all is now working. Thank you!
sounds like the slide switch is stuck closed

as an aside, does anyone have a lead on replacements for those on other Midway games?
