Why does my LG nanocell TV get broad darker lines of less light?
As you can see on the video and picture, the TV is able to produce complete background light when turned on, but a few seconds later, the light is dimmed in two broad vertical bands across the screen an continues to be like this when turned on. Any ideas what's going on? The tv is from August 2020 and the specific model is LG 65" 4K LED TV 65NANO916NA
Is this a good question?
