My TV worked fine yesterday morning. Left for about an hour came back and the TV was on (not shocking as my Vizio turns on by itself all the time) but it was flickering between 2 black screens and has a little white line towards the top. Can’t get any menu up or even shut the TV off without unplugging. Now comes the confusing part. The TV works in other rooms. Even plugged into the normal outlet I have it plugged into. If I have the TV just through the doorway to the next room It works. But if I then move it just through the door to the tv stand in the living room it starts flickering (see video below) ++http://imgur.com/a/pg9AeeA++ I have even tried another TV (another vizio) in the same spot and while it doesn’t do the exact same thing. It either does it’s own flickering or I can get it on and connected to the cable but then I can’t get the remote to work. Anyone have any ideas? It’s obviously not the outlet…or the cable box/wires. It really seems like it’s this room! But nothing changed in that hour I was gone haha

It is not obvious to me that “it is not a cable problem”. That is exactly what it looks like to me or at worst problem with the HDMI socket of the TV or the connections boards etc. Also the TV turning itself on is totally abnormal as well.

It’s the batteries in your fire stick remote , it is sending bad signals causing it to turn off the TV.
