Hi, looking for some advice about this kind of issue I never had before, this is a 25K7197 monitor from a MK II machine I got that was in storage for too long, so before turning it on I replaced *almost* (more on that later) all its capacitors because they didn't look good.
After that I've put the monitor in the workbench and it works nicely, but I'm having issues adjusting the vertical height.
Turning the vertical pot from the remote, or the 50/60 HZ pot changes the vertical height, but at the same time the monitor slowly returns back to its shrunk size, displayed in the picture. It doesn't matter if I adjust it to be taller or shorter than that, it just returns back to that size by itself!.

I've replaced all capacitors minus the 10uF bipolar ones, because the ones I could get had more ESR than the originals. There were 4 of them, one in the add-on board and 3 (I assume for R-G-B) in the main board. Could the one from the add on board be causing the issue, or what else could I look for?
