I am planning to buy the Pioneer PDP-435 HDE. I was told, by the HiFI bussinessowner that if you want to avoid burn-in problems, through for example a little icon broadcasted by some canals, you better leave the plasma on for the first 24 hours(I think he sayed to project a white screen, but I'am not sure). What your'e actually doing is the 'lightly burn/toast' the screen to prevent a bigger burn -in through little icons or text. What do you all think about this? I don't want to risk throwing bucks into the toilet.
