This glitch began appearing last night. When I first turn on the tv and the chromecast with google tv the images appear clear and visible. After I move the selection box with the remote the screen begins glitching. Then shortly after the screen looks like the photo. I tried to follow the troubleshooting tips but could not see the settings anymore!
I am assuming this is a fault, but thought I would try here first. I purchased the device in January of this year.
