Roku Ultra LT losing its HDMI connection to television

I own two Roku Ultra LT streaming devices. Both have the identical issue. When I turn it off at the end of the evening of watching our favorite shows. It turns off and everything is fine. The next day, however, I get the message that the television cannot find an HDMI signal from the Roku device. If I disconnect power, wait a minute and reconnect the Roku restarts and everything works as expected.

This was first noticed on our Visio but I've now realized I have the same issue on other TVs. I've moved the devices around to different televisions (standard troubleshooting process) and the problem follows Roku from TV to TV.
I tried changing the display settings in the Roku from Auto to 4K HD and other things I've seen posted online and none of these home remedies work. We love Roku but I'm not going to get back up and go  reset the power every time I want to watch my favorite show.

Please help me resolve this
