iMac Powers Up, Black Screen and Not display at all
Hi,
I had this iMac 24" A1200 which has defective Video card. The computer has worked but has pixels and artifacts when using a little bit of graphics.
I had send the VGA card for a reballing and we change the GPU and when it comes back, the iMac show LED1 OK; LED2 OK; but LED3 and LED4 are not lightning.
The iMac has open; black screen and the power button is "ON". All fans are working in maximum and something is not working properly.
I had purchase another video card which i think its that the problem, but the video card has the same results.
The video card which i purchase, it come from another "iMac" which is the logic board capacitors is defective, the pc was just rebooting.
Samething.
Now i would like to know, what can i do more? i've try SMD reset, nothing happen.
No chime. All capacitors on mine is look good (no bursted capacitors).
Can something get wrong with the logic card?

How about creating your own question as this is such an old question to carry forward
