I own a larger version of your same model. I play Destiny pretty often and no burn in. Do you have pixel orbiter enabled? Have you tried the screen wipe for a hour? Maybe you just got a faulty TV. To all the folks giving him grief for getting a plasma, they have advantages and disadvantages: Burn in is non-existent for newer plasmas, black levels are amazing and they tend to be 240hz standard. But, they are heavy, much thicker than lcd/led and are being phased out which probably means they'll become harder to repair as parts become slimmer.
