Re: Old Emac CRT Vertical Hold

To my eye I'm seeing a section of the screen repeating vertically with ghosted copies and the whole thing rolls. I tried a camera to get a decent shot without the persistence of vision effect and if i catch it at the right moment in the roll it shows the entire picture is there with no distortion. Though I think it's moved up slightly.

Apparently the IVAD cable is a pretty common problem with these so I think your right and whichever wire controls sync has a problem. I'll take it apart again and test the cable with a multimeter.

Hi

For awhile now I've been trying to repair an old eMac G4 700, it's an education edition cousin to the iMac.

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.

I doubt thats it, the picture is perfect, it just rolls.

Hello
An Australian here from a remote enough location that mail order parts are almost always a week away. Fixed one thing but that wasn't the whole problem? Wait another week for the next set of parts.
Mostly just trying to repair my hoard of old tech thats been sitting in my shed for 10-30 years.
