4K TV? 1080P How long is the cord run? Do you have a proper HDMI cord? Do you know what version it says it supports, bandwidth, etc.? Does the cord go direct to TV input or is there an AVR along the way? If there is an AVR then there are 2 cords so cord questions applies to both.

Thanks, my prompt was a little different, but I just reset the video to default and the flickering stopped.  You directions allowed me to correct the problem.

My brand new Vizio 70" TV with 4k HDR 60fps. I bought a new Roku Ultra and I'm having the same issues. 

When I turn the TVs input settings to Full HDR on, everything looks beautiful. But when I turn the TV off or swap inputs, and then try to go back to the Roku. Or turn the TV back on, the Roku flicks static pops and eventually tells me the input has no signal. If I turn Full HDR off the Roku flashes back on. 

I've tried all combinations of settings between the tv and Roku, both on auto detect. Both on full HDR. Advanced Roku display settings, tried all. Please help.

Check the System/Advanced Display Settings/Frame Rate Matching (might be named slightly different). Make sure that is off. I cannot watch playback of ripped DVDs because the frame rate matching causes video stuttering. It might be causing your issue as well.
