Is my logic board, or my power supply, or my RAM gone?
My imac won't start up.
When I press the power button I can hear the hard drive and the fans working but no chime.
I've checked the RAM, by replacing.
When I took off the LCD to determine if the failure is related to a faulty LCD, I powered up the machine without the LCD connected. This resulted in blowing the fuse.
The diagnostic LEDs 1-3 are lit.
Has anybody a clue on that?
Mit freundlichen Grüßen
I replaced the ram by a certified one. That should be fine.
But still the same behavior.
Is this a good question?
