No TV says Not Support!

TV worked yesterday and last night. Turned on this morning and says "Not Support!" I have trouble shooted multiple times. Turned box off and on. Nothing shows up on the screen. I am on HDMI1 channel. I am at a loss.

Did you try unplugging the box at least one minute before plugging it back in?

 

Sometimes a problem might occur during the nightly update.
