This area of powering up and down the bar has been kicked around many times.

Here you can use the Chat at samsung.com or 1800SAMSUNG but I want to write this area has been kicked around so much that I'm always checking the product manual to see what works this time. On bluetooth the last time you could not auto on/off the bar. Annoying thing. And for power off it would time out and power down many minutes later but only on optical.

This area needs work. The support folk need to not lead you on and build up your hope.
