iMac 24" will not power on (logicboard or power supply?)
I have a iMac 24" (A1225) which will not power on anymore.
power on button gives no responce.
Looking at the status LED's i have the following behaviour:
Power cord connected.
LED 1 is on.
pressing power on button,
LED 1+2+3 is on, fan starts running, then after 2-3 seconds all LEDS out.
iMac does noting. Also LED1 stays out.
After taking of the power cord en reconnecting it LED1 is on again and the whole sequence can be repeated.
Is this a power supply failure?
or a logic board failure?
Update
Unfortunately not.

Update::
I had no boot chime.
Just the LED sequence as mentioned above.
I removed the videocard and now it is giving me the boot chime.
And it stays on !
So i think a new video card is the answer.
Can i put a GT130 card in this machine ??
Это хороший вопрос?
