"Thick black stripe on iMac screen after attempting HDD to SSD swap"에 답변I opened my late 2013 27 in iMac to replace the broken hdd earlier this week and when I put things back together the screen stayed black (4th diagnostic light isn’t lit either,) one of the pins was bent on the vsync cable so I bought a replacement but still the screen is black. I was very careful with the screen, used the ifixit tool etc. Any ideas?
