Red pushed off to the side

[shipwreck00]

So I have a NAC and the monitor has been recapped and reflowed. Works fine for a while then boom red goes out and you can see it’s pushed over the side there in the picture. How do I fix this from happening? Any help would be greatly appreciated.

Funky issue. It's definitely the monitor and not the board?

Same issue with other boards as well. It’s very strange fires up fine then eventually boom red goes out then it’s shows over to the side like in the picture.

UPDATE*** I’ve narrowed it down to something with the chassis. Tested all wiring on the from the jamma edge and multiple different boards. I hooked up my other monitor and there was no issue with the color. So I’m guessing I need to pull the chassis again and look at the resistors on the neck board.

Correct. Tried different boards and had the same problem. Luckily I have two NACS so I tested with the other monitor and there was no issue with color. So I’ve at least narrowed it down to the chassis.
