iMac doesn't boot anymore, Service LED one and two light up
Hey there folks, I have an IMac 27' 2017 A1419 EMC 3070 with 32 Gig Ram and the I7 7700k.
It startet with random shutdowns, after unplugging it for a while it was fine for a few minutes and then the same procedure all over again., until it wouldn't boot anymore at all, just starting with the fan on 100% and then shutting down, repetedly doing that.
My suggestion was Overheating so I took it apart and cleaned everything + new thermal compound on GPU + CPU.
Now the IMac only shows the first two service LED's in green and the fan starts normally.
Any Ideas on why I can't get an Image or something?
Is dit een goede vraag?
