I just purchased a 64" Pioneer wide screen RPTV. My question: Is it possible to experience burn-in from watching a lot of news on the 24/7 news channels such as CNN, Fox News or MSNBC. The idea occurred to me that they all have similar black boxes across the bottom of the screen with ticker tape-type displays. I also wonder about the ever-present scoreboards like you see on baseball games. Does things like this cause burn-in? If so,would there be any liability on the part of the broadcasters? I would be interested in hearing any comments anyone has on this. Thanks in advance.
