iMac Diagnostic LED question
I am trying to troubleshoot my 07 Intel iMac (EMC 2133) which is refusing to turn on. No chime on boot, no noise of spinning HDD, nothing....
I removed the front and tried to get some idea of what was going on from the diagnostic LEDs located next to the RAM slot. Unfortunately, none of the 4 lights showed any activity whatsoever.
Is this indicative of a dead power supply or is the whole logic-board, PS, etc toast?
Is this a good question?
