White vertical lines.

White Vertical Lines.Two months after July 2016 setup these lines started to appear. They seem to have gotten gradually worse. I returned the same model, UN65JS8500FXZA, after experiencing the same type problem. That first TV had a large white spot in the upper left corner. I have tried many suggested picture quality tweaks. Gamma: -3

Black Tone:Darkest Dynamic Contrast: High Smart LED: Low Cinema Black:On. These settings mute the intensity but, as seen in the photo, they do not remove the lines. Any assistance would be greatly appreciated.

I'm sorry to hear that, does this occur on all sources and during the picture test? If it does please send me a private message with your full model and serial number?
