Please help - TV issues almost black screen, won’t respond to remotes

[Ajb84]

TV was paused in AppleTV app. Went black, then partial picture with large black ‘cloud’ spread across the screen. Then the TV closed the app itself and terrestrial sound came on but screen again had a large black cloud with only two small areas of pixels. TV powers off then on by itself, each time the black cloud is still there and doesn’t change but there is aound. No remote controller will work, not even to turn the TV off so no chance to reset through settings. Switching it off at the plug again does nothing, TV comes on as if never switched off and the cycle of on/off black screen with a few pixels and sound, over and over. I also tried unplugging and pressing the button under the logo at the front side for over 1 minute but no change.

Pictures attached. Any help greatly appreciated. Is it fixable?! Model UE50AU8000KXXU

Hi @Ajb84  May not make a difference but try unplugging for 5 minutes  before trying again. check connections are secure, could try reconnecting  cables to see if that makes any difference.
