Flickering display issue on my iMac
I’m attaching video of the issue I’m facing:
Messed up screen! When sliding the Brightness control slide.
What could be the issue and how to fix it? My model is with GTX card and display is SD F2
Well, the good news its not your display! The bad news is your backlight control logic within the main logic board has a problem!
This will need someone with deeper skills as you’ll need to dig into the circuitry to locate which capacitor, coil or chip if failing.
