I have a Roku Premiere and it has been working fine on my Samsung tv for months now. I went to bed last night and when I got up this morning I now have two black bars on either side of my screen. The menu screen and when I try to play any of the channels all still have the bars. I've tried unplugging it and factory resetting it but I can't get rid of the bars. Is there any other way I can go about getting rid of them?
