I don't even think my Sony Android TV is capable of turning off! Press power on the remote and it goes to sleep. Ok, that's fine. But when an app is unresponsive I have to hold the remote power button for something like 6 seconds and it only reboots the TV. I can't even find a software shutdown button.
