Hi
For awhile now I've been trying to repair an old eMac G4 700, it's an education edition cousin to the iMac.
Specs https://www.macintoshrepository.org/...52-emac-g4-700
I've replaced drives, memory etc and now ready to do a fresh install. But at some point I think I've bumped something and the screen now shows a picture but rolls vertically. I've tried the service manual but it's go to for all screen problems seems to be replace the cable.
Manual
I doubt thats it, the picture is perfect, it just rolls.
I can't see anything I've obviously bumped and the only adjustment options I can see are 2 pots on the side labled "V" and "Focus" then a set on the tube under "YHC", "YV1", "YH", and "(delta symbol) V". None of these seem to be an obvious 'vertical hold' to me.
Does anybody have any familiarity with these old CRT macs or just enough with CRTs to tell me where I might find the culprit? I spent a month waiting on parts and was finally ready to reinstall the OS when this happened. Frustration... yeah a little.
