Hey @Michael_b - if you do and you could that would be extremely helpful and greatly appreciated! As I understand it, it is the USB2.0 models that have this power supply - You can tell by looking at the screen of the iMac - the word “iMac” is written in the newer font (Myraid?) rather than the...

Hey All, hoping someone can help point me in the right direction. I'm working on a later revision iMac G4 that has a dead power supply. This is one of the later "USB 2.0" 1Ghz revisions and it has a Samsung power supply unit in it with model number: PSCF161101A. The first thing I noticed...

@AppleWoz in my case I ended up tracing it to the diodes that make up the bridge rectifier - which on the 120V AB are CR23 to CR26. One of those was shorted and hence it was blowing the fuse. I fixed that but the AB still seemed to have bigger issues - although it no longer blew the fuse...

Hey Andrew, how did you end up going with this? I have just got my hands on a Performa 5260 as well that is dead - the only difference from what you described is I can hear a very faint ticking coming from the power supply side of the unit when you connect 240v to it. I've dismantled and...

Hey Andrew, how did you end up going with this? I have just got my hands on a Performa 5260 as well that is dead - the only difference from what you described is I can hear a faint ticking coming from the power supply side of the unit. I've dismantled and visually inspected the power supply...

Hey All, I have recently managed to get a troublesome Mac Color Classic logic board that would not boot to "kind of" start working. I completed a full re-cap and ultrasonic clean of the board, but it was still not powering (nothing happened when pressing the soft power button on the keyboard)...

Hey @EagleTE, did you ever end up solving this one? I have a similar issue with a Color Classic AB at the moment.

I'm also facing a similar issue with a 110V Plus AB that was plugged into a 240V supply - about to start diagnosing the components. @Will-cheyney did you end up having any luck solving your problem here?
