What is your TV screen, and how is it connected to your 722k?

65" HDMI

I would try another input and/or HDMI cable, but I've seen this before and it's usually been either the receiver or the TV's GPU is shot. If you have another TV to use as a test, you hook the 722 up to that, or if you have a Bluray on the 65" that works fine, either test could isolate the problem

Do you have another HDMI source (Blu-Ray, etc.) to test?
