I just purchased a Roku Ultra to Pair with my legacy Sony 1040 receiver and my new Samsung Neo QLED TV. When I setup the Roku which plays through the Sony receiver to the TV the power function does not seem to work. I did got in the turn off the power down function that powers the Roku down after 20 minutes of use. This seems to work so far but the Ultra power function does not seem to work from the hand held remote no matter what I do. If I leave the 20 minute power down function on I cannot turn the Roku on at all with the remote and have to unplug it before it will operate. This seems like an issue that should not occur.
