Does my G5 isight have the 4 LED light diagnosic facility?
My iMac G5 20" Model A1145 (isight) turned itself off whilst I was out and now seems dead.
I did a little research and found a great step-by-step diagnosis guide on the Apple site - it said the G5 has 4 LED diagnosis lights that can help you narrow down the problem.
At this stage, I was feeling a little more hopeful when I saw an annoying note to the effect that the guide did not apply to the G5 iSight model.
I researched a little more and found this site and checked out the guides for my model. They seem premised on the idea that you already KNOW what you want to replace - eg power supply.
My problem is that I DON'T know yet, and I was hoping to use these LED diagnostics to help me with that. Using the guide for displays, I started the task of getting the case off and unplugging stuff with a view to having a look if they were there.
However I came to a part that needed me to employ a T6 torx screwdriver and I don't have one of that size (yet) so I'm going to have to go and get one from somewhere tomorrow but it just struck me that even if I find one and get the display out, I'm not sure if these LEDs are even IN this model.
Does anyone know? Needless to say, I am WELL outside the warranty period...
Is dit een goede vraag?

My model iMac G5 20" (Isisght) hasn't been able to boot up since yesterday. I left it on sleep mode last night and, when trying to wake it up, it started blowing air out of the fans.Nothing seems to work (SMU, Pram..)I opened it up and looked at the 4 LED diagnostic and only LEDS 1 and 2 remanin lit when I turn it on. I suppose that everything is fine with the logic board but still the computer won't show any picture or boot up. After a couple of minutes the fans come on.No response from the keyboard either.I ran out of ideas and I would appreciate the help!
Thanks!
