I have a samsung UE46ES5500 TV (which I bought 8 years ago), since 1 year I started noticing some pixel bars on the right edge of the screen in red color. It evolved now and I have a black band starting from screen right edge (band width is approx. 10 pixels), and the red pixel bars moved a little bit inside the screen. It's a bit hard to explain so I attached some pictures as they are better than words.
I am a bit afraid that one day my TV will refuse to switch on so I wanted to know the root cause of this issue.
Thank you in advance for your support.
Thank you for your feedback.
The problem is happening with all sources (and even when playing videos from a USB stick). I ran the picture test as advised and it's still there, so I guess I will need to contact a support center for this...
I am having a similar problem as you but my vertical black/shaded band is center-right and a small band that is center-left on my screen. I bought my Samsung TV - Samsung - 55" Class - LED - NU7100 Series on 4/20/2018 and I can't believe I'm having problems already! I only bought a 2 year extended warranty so I guess shame on me for having faith that Samsung would be reliable and that I wouldn't need the warranty extended past that 2 years. I DEFINITELY will never buy a Samsung TV again and will be going with Sony from here on out.
