Apple CRT flicker zoom in

#1 Post by ThinkPad560X » Sat Feb 15, 2025 7:25 pm

I got an Apple CRT, the one when Apple was doing the 2000s color see through of their devices. This monitor was hard to find as usually they are very expensive and or pickup only. It is in mint condition and matches the G4 tower I have "Grey or Grey/blue" I hooked up my Powerbook G3 via VGA of monitor and powers on and show clean image. After awhile the crt will click flicker and started to zoom the image in close with the light getting dim. I don't see any burn in images like if it was on 24-7

Monitor is this type but different color: https://www.lakemichigancomputers.com/p ... ite-tested

by the looks of it, it is a faulty flyback.

They can be fixed with buying a replacement flyback. But have to take monitor apart and desolder the old one. I am not sure if there is a way to clean/ fix the flyback that is in it.

Have you tried an Apple website?
