Hi I'm kind of new to this. I'm the happy owner of a 37" Panny Viera plasma. I've read a lot about "burn in" period of a new plasma screen in these forums. Most say keep the Viera in normal or cinema mode for the first 200 hours. What's the point of this ? I have had my plasma for a month now and have kept it in dynamic mode all the time but have decreased the contrast and brightness level though. Am I in trouble or what ?
