I just purchased a Toshiba Theaterview 43H70 today. I got my TV home, and noticed an outline of what looks like The Weather Channel emblem in the upper left hand corner of the TV. Its only visible when it goes to a light color in the corner of the TV. I'm a newbie on the TV scene, so my questions are: A) Is the TV's life span about done; B) What can be done about this problem; C) Is this a common problem on big screens? Thank you so much for any help. I'm a little bummed, and any input would help. Thank you.
