Ive got a samsung 50" plasma and i had it around 3 months and got screen burn in the top corner of the turbo symbol, also when pushing the i button on the sky remote in the time it took me to read about the program i was watching it would burn the screen, so i called the engineer out and he said its unrepairable without a new screen and its not covered by warranty, so i took it back to the shop and said what had happened and they gave me a brand new one which was a newer version so i was lucky, i made up some story about the setting etc and it worked for me.
