I have the Samsung QN55Q7CAMFXZC TV The TV started to have flickering horizontal lines at the top of the screen. The would appear, make the screen blurry then stop for 2-3 seconds then do it again. This happens over and over. As the TV stays on the lines start to appear at the top and bottom of the screen then ultimately happening across the entire screen. There is no response to posts that explains why this is happening. Just to open a support ticket. But could someone say what's causing it? It sounds like it’s to do with overheating but that’s just an observation. To anyone else that’s also having the same issue I hope this post ends up something that can help you too.
