Samsung QLED White/Washed out screen - Main Board or LED Driver Board?
Samsung QLED QN75Q8FNBFXZA
Hello!
Not exactly sure how to describe the issue with this tv, but the screen is completely washed out - picture displays and issue is independent of input as the problem is also present on built in smart tv menus. Other ways to describe the issue is greyscale or slightly negative picture?
I've found similar issues via research online but with older tvs that have a T-con board. My tv does not have a replaceable T-con board.
I've taken the tv apart and have performed a handful of tests but it hasn't gotten me any closer to a root cause.
Would appreciate any thoughts from the pros as to whether they think a replacement of the LED Driver Board or Main Board could fix the issue?
Images of issue attached. Thank you!
