Worked fairly well before i switched out the chasis. (Had a color dial in problem with red) so i just switched out with a spare i had. Now the game select screen scrambles. Doesnt matter if its top monitor or bottom. Wiring does not appear loose at any connectors. Anything i need to look at better that i am missing? New chassis had an actual plug instead of connector. That was the only difference but font think that should have mattered.

Even though they are both doing it, I would play with this pot…. If you don't already have plastic monitor tools I would pick up a pack and adjust it while its running.
 
I recently fixed my Joust monitor that kept losing sync. Turned out it was a cracked solder joint on one of the pin headers.

I will try this here in a bit to see what happens. Thank you for reply and suggestion.

I will look. Thanks for the info
it sounds like it's a signal issue, not a monitor one?
Think this could be it? Both monitors work. I tried another board and same thing. So maybe some sort of interference. Could it be wire harness? But seems to be a 2 monitor deal on a Playchoice .

yes, if you switched signals between monitors and the scrambled screen follows then it's not either of the monitors at fault. the edge connectors to the filter board have those solder eyelet gimmicks on them under heatshrink and they can break off. I suppose another thing to try is the rule out the super rare instance that the filter board is losing something is to plug the edge connectors into the PC-10 board directly?
 
I followed down. All seemed to be good. I started wiggling. Then wiggled aggressively and snapped one. 😬. The are a pain to deal with. I will try to solder. It back on. But really nothing to attach it too. Then i will mess with the white pot on the middle of the board.

You can pull out an unused pin… they do pull out and you can slide it back into the broken spot. I use a little angled pick… they pull out from the edge side.

Monitor was working. I moved this a bit to see what it did. Monitor stopped workings . 😬. I can still hear game selected.
 
I dont think my harness is the issue anymore. I have 2 pc10 dual monitors and hooked up the other harness and same issue occurred. So i think there is some sort of monitor interference with each other. Still trouble shooting though. Any other things to try and test?
