I have a 55inch tcl roku tv that recently started having a black vertical shadow that's about a foot wide near the middle of the TV. I contacted tcl and they were no help besides telling me to call my warranty company. This was bought in Dec 2016 and is out of warranty now. I can still see the picture but in that area it's darker than the rest of the TV and it's pretty annoying. I've already restarted it, removed any components/hdmis, and did a factory reset. Nothing made it go away. Any suggestions, or is it shot?
The shadow does look darker in person
