I have a UN78HU9000FXZA Curved TV. It is connected through One Connect box. It is out of Warranty. I am experiencing display issue where the display had a permanent blue bar on the right side of the display See pictures below. The issue is not present when there is a static photo. Otherwise there horizonal lines across the display. I have reset the TV through Support/Settings but the problem persists. I am wondering if the issue is in the One Connect box or the TV display. Any help will be appreciated.
