Ok so I have some issues with a monitor in a game I am working on. I have zero monitor repair skills, but wondering if this is something super simple, or if this is just one I should send out to a pro or at least try a full cap kit on first.
1) The blue works SOMETIMES. See attached video. If you bump the machine, the blue comes back in. Sometimes it stays for a bit. The jank job that they did with the molex connector on the board could certainly be responsible. See that picture below as well for a laugh. They had also literally just jammed the pins for the power to the monitor in to the existing molex connectors on the monitor board - I actually got the correct molex connectors for these so they're no longer just electrical taped pins jammed into one side of the molex. But then I noticed this little workaround on the video signal to the board.
2) The monitor shuts off completely sometimes, then turns back on later. Then turns off again. It's not consistent. Seemingly random. Will play for an hour, then just stop. Then if you turn it off and wait a bit, turns back on fine. So it's not totally dead. They also used what appears to be like a lamp power cable to run power from the iso transformer to the monitor. It's thick enough wiring, so presumably this is not the cause of the issue, but if so, I could easily replace that as well.
3) The screen shakes vertically. It isn't the V hold, that is fine, but if you go to the test menu and look at the monitor test screen, it's like it's shaking up and down a tiny amount, very quickly, all the time.
Any help would be appreciated here.
