I work with computers all day, every day and screen burn in is real. That being said, I've only seen it on one screen over the last 6 years. That was on a screen that is connected to a server that records data from surveillance cameras. It is on 24/7/365....and it took several months for the burn in to occur. My Wii is connected to an LCD flat panel HD tv and I don't have any concerns about it. Like I said, it takes a LONG LONG LONG time for screen burn in to occur. Even if you left a game on pause for several days straight with the TV on, it wouldn't even be close to causing burn in. Tell your parents that white89gt said its ok. That should be enough to change their minds........everyone knows me!!!!
