Brown line in the middle of my screen on my Samsung curved TV. Image looks fine just dark. What could it be? Update (07/27/2018)
The back light has a problem on this set. I don’t recall whether the LED strips are vertically mounted or not, but I would suspect that they are. You have a failed LED strip. The back light is generated by a number of LED strips for even light distribution. With a strip out, you would get a diminished area as seen here. Your options are to replace the entire strip or have someone replace the defective LED(s) on the strip. Dan
I have a similar problem with my TCL Rocku Tv but this one goes away if I reset the tv and it returns after few minutes, so I don’t think is the led stripes, should be something else.
