I bought this TV in November 2016 and it's been great. Out of the blue the shadowy vertical line appeared near the center of the screen that's a couple of inches wide. Not sure what's caused this. I can't feel any damage to the screen/glass. Happens in multiple inputs and in all 3 of the self diagnostic screen tests. Please help!
