I have a minor frustration regarding my Apple II+ clone's display output: it keeps rolling vertically and is very hard to set in place.
Normally I would adjust the monitor's "V-hold" trimmer (on the back of the monitor) and when slowed down (i.e. it moves up or down very slowly) it'll "lock" or "click" in place, but for some reason this isn't happening now. I've done a lot of troubleshooting lately (colour was gone which I've just fixed) and this has happened again (it's happened before, then for some reason disappeared). I don't know what's caused it to disappear but I suspected the video cable being too close to something interfering or something like that.
Basically it's just really hard to adjust the rolling. Any ideas?
