hi, I read these forums with absolute fascination with the knowledge you guys have and although I too have always had an interest in TVs for many years cannot hold a candle to your knowledge. screen burn scares me a little and whilst I very much like the look of the AF9 this subject still concerns me. I have had my panny 55vt65 plasma for over 5 years with over 9999 hours clocked without a hint of screen burn. The one thing I did however was to get the screen calibrated. It took a full day to calibrate which also included the 3d as well as my sound system. Would having, for example, the AF9 calibrated reduce the potential for screen burn? I have a seven year old who still loves her children's channels and would never stop her from watching for as long I see fit not the TV's "misuse" policy. Are most TVs that exhibit screen burn already calibrated. Is it just the nature of the tech used or just down to luck as to what panel you get of the conveyor belt?
