I am specifically talking about a 50” Roku Tv set, not the little stand alone streaming device that stays on.
fyi, my appletv little streaming device does not stay on, but turning on it (which turns on the “external” tv as well) comes right back on the channel I was last viewing whatever the app, for example the youtubetv app.
it seems pretty lame to purchase and connect an “always on” or an appletv to plug into a Roku Tv (50”) with built in Roku streaming. indeed, my neighbor, who i an helping, already had a Roku streaming device. He needed a new TV so i suggested the 50” Roku.
and it performs worse than the $30 Roku streaming device.
worse = the issue in my op. powering on to the app and channel last watched., eg, the youtubetv app tuned to the last viewed channel/network, eg, CNN… or other — last watched.
