I have an old iMac 2010 27" i7, High Sierra + Windows 10.
It's a perfect computer and has always worked well over the years.
Over time I changed DVD player, CPU and GPU thermal paste, installed SSD ed a SSD thermal sensor, cleaned the fans several times and also cleaned the display which accumulated dust in the most superficial layers.
I have completely disassembled the computer several times over the years, so I know it very well.
For some time now I have noticed that the screen has changed hue to yellow, if it was barely visible before, now it is noticeable quite quickly.
I did a search on the net and the problem seems to be the coating of the backlight LEDs which is literally cooked and makes all the backlight yellow.
On ifixit I found these very explanatory photos:
another problem that I'm finding is that when it gets very hot the bottom left corner tends to become darker (not as dark as in this photo, but the flaw is barely visible)
and this is also a known problem and the solution would be to re-solder the connector come as in this photo found on the net:
Probably the best solution is to change the LED bars, because they cost less than 15 dollars.
Not having the time to get back to work on this imac, I'll try to calibrate the display with calibrite colorchecker to see if the situation improves and if I can postpone the intervention for the future, but sooner or later I'll have to do it.
This isn't my main work machine, but it's a real shame having to throw it away in the trash as the monitor no longer works.
The big screen and quad core i7 processor still make it a current machine for light work and its design is still beautiful, so I'll fix it as long as I can.
Have any of you had any experience with replacing the backlight on this imac?
Do you have any advice for me? thank you all.
