Maybe someone might be able to help? At work I have an Apple iMac 15" 700MHz "Lamp". The problem I am having with it is the lcd backlight does not come on, the drives do not spin up, and the fan does not spin. When I press power I hear the Boooong sound and I can see by reflection only the finder faces and alternating question mark in the lcd panel.
Replacing the power supply with a brand new one from welovemacs.com did not help, much to the irritation of my boss I also reset the PMU which did not help either. The battery measures voltage of about 3.65v. When I tested the molex connector that I disconnected from the cd-rom drive, I am getting +5v on the red lead and nothing on the yellow lead.
I tested the hard drive and the cd rom drive on a Compaq Evo that I have here and they both work perfectly.
Would be appreciated!
