I've just bought a new Roku Express, and working out whether I need to return it for a replacement or whether it's just a general Roku problem but finding nothing in the way of support on this.
In the menus everything is fine, but as soon as I start playing any kind of video, I get either one or three blue vertical lines on the screen. I *think* it's three lines for 720p and one for 1080p content, but obviously hard to be sure. I've tried 2 different TVs and 2 different HDMI cables, but always the same.
Is this a known issue, or just need a replacement player?
