I have a Ue55Js8500 curved, and in its history have had a few repairs. The final repair I still wasn't happy with and had insurance payout for it.
The issueir has is an oitlout box around the screen about 2-3 inch in from the edge. It shows up in various sources and deferring colours.
I've had a look online and some people have said it's the Lcd panel (would be unfortunate as it's had 4 in the repair process) some have said it's the blocking material behind the glass ( I'm a little be scared of tearinf down but if need be) and it could be the tcon board firing up the lights wrong.
During the last couple of days before I post this the set also has been blank screening when first turns on (sound and menu still works but the screen goes blank of what ever picture is on) so maybe in my thoughts a main / av board is to blame ?
I have replicated the issue whilst loading the youtubeapp up and can be seen hopefully in the attached pictures.
Or could the issue be the famous led/colour banding ?
