iMac won't start. Powersupply?
Hello,
I have a problem with my iMac and I hope you guys can help me.
It‘s an 24“ iMac Mid 2007 2.8 Ghz Core 2 Extreme (EMC No.: 2134 Model No.: A1225).
The iMac suddenly turned off as if sombody pulled out the powercable. If I press the power button nothing happens as if the machine get‘s no power at all.
So I opened the iMac and removed all the dirt and dust. I thought it might be the PSU but I can‘t see any optical defects.
When I pluged in the powercable the first Diagnostic-LED light up shortly and went off again. When i pull the cord and plug it in again nothing happens...
I checked the cable itself and tried another one to be sure it‘s not teh cable.
Can I be sure that it is the PSU (because of the LED‘s) or could it be the logicboard either?
Any Experiences?
Thanks for your help. And sorry for my poor english.
Questa è una buona domanda?

Hello,
thank you for your answers, and sorry for the very long delay. I never thought it would be that hard to get one of those PSUs in germany. How ever I finally managed to get one.
After I replaced he the old one my iMac started up without any Problems. I had it running for a few hours for doing all the updates with no problems. But after I moved it from my workbench to my home office. It begins to boot and after 20-30 seconds it turns off. I can't turn it on again pressing the power button doesn't have any effect. When I wait a couple of minutes and unplug it from the power network I can start it again, but only for about 20-30 seconds and then the machine turns itself off again.
Does anyone have an idea what this could be? Thanks for your help.
