Bought a tv not even a year ago it's a Samsung 65" and it's been properly installed into the wall since the first day. No one has touch it and it's been cleaning and dust free since but here lately my screen has a flickering green lines while I'm playing modern warfare.
We are sorry to hear that, does this happen on all sources? And what is your current software version on the TV? If possible can you provide a picture of the symptoms you are having?
