Diagnostic LED#1 Blinks Is it Power Supply?
My Early 2008 iMac shows no signs of life... No fan, no hard drive, no power on indicator; nothing. On tear down I find Diagnostic LED #1 blinks on and off. None of the other three Diagnostic LEDs are lit. I suspect a faulty power supply board. Am I correct with this diagnosis?
