Our brand new Sony X750H 4K Android TV doesn't show up in the list of available Cast devices (for example, attempting to cast something from Netflix) when the TV is off. The TV is just turned off via the power button on the remote, so it's on standby, and it's still plugged into a turned on surge protector. This is a regression from our old Chromecast Ultra and dumb TV, where casting content while the TV was off was available and it would turn the TV on. I'm also unable to turn on the TV from Google Assistant/the Google Home app, like I should be able to do. I am able to turn off the TV from Google Assistant/the Google Home app, however.
When you hit the power button it is powered off. It does not go into stand by mode
