Visio switches to black and white display after ROKU is set up

I have tries this with Roku, Roku express, Roku express+ with same results.  I have tried resetting the Roku devices and the tv picture with same results.  I have tried 3 separate HDMI cables on both the inputs on the tv with same results. I have unplugged the tv and the roku devices with same results.

PROBLEM:

When I set up and first start up the Roku devices, Works great with good color.  When I turn the TV off and then turn the TV back on, picture is black and white.  when I then turn the tv off and then unplug the Roku, and then turn them back on it is still black and white.  I have tried using both the Roku and the TV remote to turn the TV off. All times it has come back black and white. It sometimes seems like something goes into memory after the first time roku is turned on and pulling the plug does not clear it.  The balck & while display is clear and good

I am using these the devices - to include a similar Vizio on 3 other TVs and they all work fine.

 

Any help would be appreciated
