Backlighting issues and limited brightness in iMac 5k 2017 27"
I have serious issues with the backlighting after I followed the instructions to replace the internal hard disk by an SSD drive - everything else works fine and I have no other issues. Can anybody tell me please what could have gone wrong and if I could fix that myself?
Those are the major issues:
1) Clouding in the lower part of the screen - many bright spotlights with darker spots in between
2) Brightness will not increase if setting the brightness bar higher than 7 dots
3) Screen goes sometimes completely black. No software issue as I see in very bright environment light or with a flashlight that screen itself is showing a normal picture. When it goes black, I cannot do anything to get it back working. After a restart sometimes it's bright again, sometimes not.
Any help highly appreciated!
Is this a good question?
