Super weird psychedelic screen video playback problem

[Mamsmks]

Hey, having a weird issue with the tv.

It's Samsung ue85au7172uxxh and all the menu etc looks perfect but video playback from whatever app Netflix, YouTube is instantly psychedelic looking. Didn't even get anywhere with Google don't exactly know what words to use haha :D.

Tv is less than 1 years old 

Anybody got any ideas at all :D?

Thanks !

Mamssmks I get the same thing sometimes. Have to switch off for a few minutes then it works ok for a while. Would like a more permanent fix though!
