A1312 not powering on because of GPU? LED 1 present
Past few weeks, I posted a few questions on this website regarding my iMac A1312 not turning on. LED 1 kept lit up so I know there is power coming in.
No chime, no fans, no nothing when I pressed power button.
I changed Power supply, the DC cable, power cord, logic board AND the power button.
NONE of it was the reason that my iMac does not turn on.
In my last resort, I tried boot it without GPU then BAM! I got LED light 2.
When I try to boot up again with GPU slotted in, it went back to LED 1 light only and nothing works. I know I will get a new GPU but my question is, in my countless research of LED 1 and no LED 2, 3, 4 symptom, none of the article mentions faulty GPU.
FYI, I tried the “baking GPU” just in case. Nope, it did not work. I know I will get a new or used GPU now. :(
Is it something new? or am I going down to another rabbit hole. I spent SO much money on this iMac already. Any help would be appreciated.
Is this a good question?
