I’ve tried triubleshooting the picture quality for my plasma. There is color distortion and a bunch of horizontal lines. One was a Roku 2 (I believe) and the other the Roku3. Swapped between units and HDMI cables. I’m thinking it’s the TV, but hoping it’s a setting someone can clue me into
Re: Horizontal lines with two different Roku players
Seriously doubt it's the players, since both exhibit the same issue. Of course, they're both pretty old players, and it's always possible that they have failed. Just not very likely for both at the same time. One final test would be to plug something completely different into the TV. And no, I can't think of any settings that would cause it.
