Our Roku Ultra is connected by HDMI to the TV. Following power outages, Roku restarts which also powers up the TV with Roku displaying. Should we be away for a period of time, it isn't ideal to have the TV on in our absence.
The voice remote is configured to control the TV. I tried to remove remote control of the TV, but there is no provision for that.
How do I resolve the problem of the TV being restarted?
