Chosen Solution
I just attempted an SSD upgrade on this iMac. When re-assembling, I was presented with a rather large column of dead pixels. I really hope I didn’t hurt it while removing. I was being as gentle as possible. I’ve done this before with no problem. Also, the iMac does not want to read the SSD I put in there, but I’m calling that a second-priority issue right now.
Does anybody know a fix for this? Or do I need to buy a $500 display?
I’m sorry to see that you have done so well just to end up with dead pixels. I am afraid to say that your screen has been damaged in the upgrade procedure and will need to be replaced. I really feel your pain with this one :( Sorry I could not offer a fix :(
Ouch! Not good ;-{ Did you use the pizza cutter which comes with the iMac Intel 27" (2012-2019) Adhesive Strips kit I also find a few sets of the Plastic Cards also help. Following this guide iMac Intel 27" Retina 5K Display 2019 Display Replacement to the letter is important as its very easy to damage the display either pushing in too deep or prying while the display is not fully released. Time for a new display sorry! 27” iMac Retina 5K Display Assembly, Apple P/N 661-12558 But let’s see if we can figure out what’s happening with the SSD which port did you put it into. Did you replace the HDD (SATA port) or did you install the new SSD in the PCI port? Which drive did you use? Maybe we can figure this out too so you only need to go back in once to get the system back to 100%
