recently three vertical lines have showed up on my tv screen and now this black circle. we just got this tv a few months ago and there has been no issues with it or damage to it. these showed up completely out of the blue and it’s very annoying. any suggestions?
Roku doesn't make the TVs, so my suggestion would be to contact the manufacturer - TCL, Sharp, onn, etc.
