The video output on my PCjr looks like it's losing horizontal sync whenever I reboot after it's been running for a while. When it happens, I usually have to leave it turned off for at least 20 minutes. It's been doing this since I got it in 2021. I have recapped the motherboard (and maybe the power board). I'm curious whether anyone has any ideas about why this might be happening. This is an example picture of the phenomenon.

Well, you have a couple routes to troubleshoot... is it the computer output or the monitor that is misbehaving? Do you have a 2nd computer or 2nd monitor you can connect to and see which is the culprit? From there, then you can troubleshoot the defective device.
