Roku Express 4K not working

I have two Roku Express 4K units, each connected to an HDMI port of two TVs in the house. The TV in the bedroom works fine.  All the Roku channels are there.   The TV in the living room has worked for months but suddenly the HDMI port here connected to the Express 4K is not displaying the normal Roku content.  All I see is the word "ROKU" with the individual letters of the word dancing up and down over and over, like some kind of a screen saver.

Pressing Home on the remote doesn't change the display.  In fact, no key on the remote has any effect on the display.  

Does anyone have an idea what might be happening?

Thanks.

Re: Roku Express 4K not working

If you're using the TV's USB port to power the Express try using the supplied power adapter.  If you already are using the supplied power adapter, try a factory reset.
