We've had our TCL ROKU TV 7 or 8 months now. Soon after we got it the screen went dark. After reading the replies here I unplugged the tv for at least 5 minutes. Turning it back on didn't appear to be any change. I did notice that when I pressed rewind the scenes that popped up on the timeline were clear and more visible, but main screen still dark. Probably always like this and never noticed. Anyway, I pressed the * button on remote then went to picture settings and as I was toggling through the different options noticed that we had the tv set to "movie" and once I changed to "normal" the screen was NORMAL.
