Hello there,
I recently acquired 16 various iMac's from a surplus auction and am trying to piece some together to make a few functioning ones. I have a 27" 2019 that I've put back together and am having an issue with. When the people I bought it from had them, they removed some components (presumbably to reuse or ensure sensistive information wasn't released). The one in question was missing the processor and hard drive (all of them were missing the HDD...no problem there). I pulled a processor from another machine (i5-8500 @ 3.0 Ghz) and put it in this machine. Now, evidently when they removed these components, they weren't exactly kind and bent a few of the socket pins. I feel as though I was able to bend them back using an electronics microscope and delicate hands. I even used the gird feature on the microscope that uses gridlines to ensure the pins were in line with one another. Upon assembling everything back, when it goes to boot, I get LED's 1,2, and 3 illuminated. From what I can tell, that means there's something wrong with the LCD or its connection. I know the LCD is good as I've moved it to another working 27" 2019 iMac and it works. Is there something else I should look at or is the issue the CPU and its bent pins? From what I've read if there's 3 lights on, the logic board is good. Is that correct? I've also read issues with the CPU retaining spring and it being overtightened. I've left the same gap between the spring and the board as another working 2019 iMac. Any help would be appreciated! Thanks in advance!
