PVM-20N6 jittering issue

[ElBartoME]

Hi!

I was a lurker here but now I decided to make an account. I have a problem where I'm not sure what the solution might be.

I recently found a PVM-20N6 sitting alone in my company basement. I brought it home and it still works quite well. It only has two issues:

Issue 1: The picture will get blurry if the contrast is set too high. This doesn't bother me that much really, as the contrast level where I have a sharp picture is still enough.

Issue 2: This one bothers me. There is a slight horizontal jitter. At first I thought it might be my SNES. But no, I have the same problem with my RetroPie with a Pi2Scart and with my Gamecube. Even the OSD is jittering slightly. Here is a video where you can clearly see the jitter: https://www.youtube.com/watch?v=qsCwdPxX7vA. The PVM-20N6 is the bottom monitor. I then move up to my PVM-14M2 where there is no jitter to be seen. It has a rock solid picture. Both are fed from the same source.

I suspected the capacitors in the horizontal deflection circuitry might be done for and I changed them. But that didn't help unfortunately.

Does anybody have any clue what might cause this behaviour?

Thanks!

Bump, because it took some time to get the thread approved by the mods.
