Next Friday I will be receiving shipment of my first RPTV. The set is the Toshiba 50H81. I would like to prevent burn-in and other catastrophes and was looking for help in what I should do from the instant I get the TV. 1)Is it fine to turn it on and off to check function? 2)How long should it remain on before turning it off? 3)I've heard that I should run a movie like Toy Story for 48 hours straight to break it in. Is this really recommended? Any help is appreciated.
