Hey guys,
I'm Working on imac 27, 820-00609 MB that only light up the first 2 leds..
From your experience with this model, is it common for the graphics chip to die?
The board is very clean and I can't find anything wrong with it.
I have all the correct voltages at the outputs of the processor and graphics chip power coils.
is it worth trying bios programming?
thanks
