Ok I finally returned it back and changed it for a 42" LCD...
Since I'm watching CNN a lot, then I guess the "static" stuff at the bottom of their screen would have "burnt" it a bit... As I said this is not my primary TV... Our primary one is a 46" Samsung LCD in the bedroom and we love it!
Thank you all for the sound advices... From what I understand, this topic will always be 50/50 depending on who you ask... A bit like the Beta/VHS debate in the old days
