I watch a movie, or SetTv, or netflix, and it always pops up with a pink box and a timer saying it's going to sleep, and I have to hit enter to stop it within 30 seconds. The problem is I can't find where to change it. When I find the sleep area, the max you can pick is 30mins. Sometimes it's longer than 30, sometimes it happens multiple times in a couple minutes. Anyone know how to fully shut that off?
