I bought this a year ago and it's been an awesome tv but I just noticed today that there's a red dot right in the dead center of the screen. It only appears on colored images, not black and white. It's annoying once you notice it too. It's kinda like someone's flashing a red laser at the screen. I bought this tv at best buy and got a 2 year warranty with it so they are gonna come and check it out but I was wondering what the possible issue is going on with the screen? Anything I could fix?
