seems my 55" b7500 has bit the dust out of the blue, i noticed it's been turning itself on randomly during the night but thought nothing of it figured it was the sound bar or something else causing it
it got stuck in a bootloop but resolved itself a few weeks ago, today i've turned it on for the first time in about 20 hrs and the screen seems to light up but no picture, just sound on any input, no vidda logos no menu items etc nothing.
TV isn';t even 6months old...
