I swapped my 27" iMac 2019 model 's HDD to Samsung 1TB SSD. Original aim is successful and the iMac is blazing fast now.
I connected it back and closed the iMac. When I powered up there was a black vertical line on the left of the screen. I changed the Lvds cable but still the same issue.
Any help would be much appreciated thanks.
