A:Answer I'll answer my own question for anyone else who needs it: you have to disable samsung's "TV+" app to get the TV to stop auto-playing random channels. now the TV tries to start on a cable channel, but since we dont have cable, it just gives me an error message and i hit the home button to get to my apps. i shouldnt have to do that. for this price and samsung's reputation, this TV should have a user interface that works. this is stupid.
