Backlight on display is black on half of the screen
My iMac Intel 27" EMC 2429 2.7GHz i5 has a large black area that looks like the back light has gone out. How do I know whether it's the backlight board or the LED?
Or even the video card? As suggested by Mayer in this post- Backlight dim in a part of the screen
I appreciate any help or feedback. Thank you,
