Samsung PS50C450B HD Ready Plasma TV with Freeview

I have had my Samsung plasma tv for about 3 weeks now. I must admit i was amazed with the picture quality, Sound And also the style. Great buy? ....Disaster strikes! I was on my xbox 360 for roughly 3 hrs or more. And the game i was playing gives you a weapons display, Unfortunatley so does my tv now that it has burnt it into the screen =/. And not only that the samsung tv comes with a unique plasma burning preventer.... Erm... Well that dont work =/ . I cant say im happy with this as it cost me an arm and a leg. I guess i will have to flick through the manual and try and figure out this " Unique plasma Burning preventer " Would i recomend to buy? Yeah if you have money to burn... Otherwise it''s a no deal. I hope you all find this useful in future reference.
