Power - on Failure (mostly)
IMAC 20'' 5.1 late 2006
I have a "funny" failure with my 20'' IMAC.
First - month ago - he didn't want do start with the first try, but he came...
But it was getting poorer - and after a longer time and not using he wouldn't start.
The power-supply was not ok. One capacitator war blown. I changed it.
I changed the big 150mf 420v too.
First: no succes. LED01 is blinking.
The ventilator "tries to turn". (neerly not to see, so little)
But: if the IMAC ist connected to 220V and I seperate the connection that comes from the power-supply on the mainboard and put it together after some secondes, LED 01 ist ok and the IMAC works.
Anny idea to fix it?
Is this a good question?
