Backlight won't turn on
So after I upgraded my late 2015 iMac 27" and put it back together, the backlight did not turn on when started up.
Its just the backlight because I can see everything on the screen if I shine a strong light on it. I recently looked at the diagnostic LEDs on the logic board and the 4th one will not light when starting up. That leads me to indicate the issue is with the backlight board.
Any thoughts on how i can fix that?
Or, could it be an issue on the display side like the connections? The connections were good from what I could see.
I can't seem to find any info in 2015 iMacs.
Ist dies eine gute Frage?
