Ive had green distortion on my tv and I have a roku stick. How do I uninstall roku and reinstall ?
You cannot "delete” Roku from a TV. Since you are using a Roku player that is connected to the TV, simply disconnect the Roku and it's gone from the TV. I doubt that will resolve your screen issue though. That sounds more like a TV failure.
To "reinstall" your Roku Stick, simply connect it back to an HDMI port on the TV.
All apps? One app? Even the Roku UI? Is the TV normal with other sources?
A Roku device pretty much works like any other device like a blu-ray or cable box in that it sends a video signal to your TV, in Roku's case by streaming it through the internet. Just like any device that attaches to your TV, it does not install or uninstall like a computer tends to do. Just simply unplug it.
As ATC said, it does sound like a hardware issue with the TV. Have you tried the Roku on another TV?
