I have a terrible habit of watching TV while lying down, so yes, I fall asleep with the TV on quite frequently. Fortunately it's usually while streaming something on Plex, so I'm not running it all night or missing an entire show of something, since it stops after each film unless I'm in a playlist, which is rare, and then everything enters power save mode when not in use for so long, so it's not a massive drain on power when it happens, fortunately.
