No Power, Diag LED #4 briefly lights...How test Pow Sup and MB?
Dead IMAC.....is there a procedure short of replacing the power supply and the logic board?
Once you remove the LCD, you can see the 4 diagnostic LED's on the Logic Board.
When I apply AC power, LED 4 breifly lights up and then goes dark. The Start button does nothing.
Is there a way to test the Power Supply?
How do I know if this is a Logic Board issue?
I bought this with a known issue and no ram and no Hard Drive.....silly me.
Bu iyi bir soru mu?
