Do you have another tv you can try this on? If so, I suggest you try to set it up there. When it's working, go to Settings > Display type and set it to the actual resolution of the first tv instead of the "auto" setting. When you get the countdown screen click on the "yes" option. Now move the Roku back to the first tv and see if the problem is solved.
