My imac intel 24 alum 2.8Gh Emc2211 won´t do '''anything''' when I press the power button. I´ve checked wall outlet, power cord, opened and cleaned the dust in it. I´ve read that probably power supply or logic board may be the culprits. I want to repair them myself. How can I be sure which one is responsable. Is there any way to test it when, I repeat, my computer does not give any signal of life (as if it would be unplugged) Thanks for your help

Hello Mayer, at last I received the Power Supply yesterday and I assembled it a minute ago. '''My iMac is back in service!''' for a few seconds I was afraid of pushing the button and not hearing the chime... but there it was. Thanks again for your help, and thanks also to the members and participants of the ifixt it site.
