WG19K7901 has sold red screen, plays blind. Game board works 100% in another jamma machine. Not sure where to go next with it? Just recapped it. I tested the pots and transistors on the neck board they seem good? Can't seem to find much on the boards about monitors with solid RED screens? Thoughts?

If you've tested all the pots and transistors on the neck board and verified that they are good, then you have a picture tube failure. The good news is it's possible to fix it with a rejuvenator. There may be another KLOVer nearby that can help you out with that. Just for grins you may want to pull the red drive transistor on the neck and fire up the monitor without it. If you still have lots of red then you know for sure it's a tube failure, but if the red goes away, it's something else on the chassis.
 
Hmmm well I just fired it up and unplugged the video input signal, with no change????
Thoughts?
 
SOLVED! The video sync wire was off at the Jamma harness! Works perfect now!
