Hi everyone! I need some help. I am a total electronics idiot. I just purchased the Vizio E601i-A3 last weekend. Bought it from a local discounter for $790 plus tax. Got it home and hooked up to AT&T Uverse. The picture looks like there are color "halos" all over the screen. Not constantly but most of the time. Like a flourescence. They are different colors based on what is on the screen. My kids don't think it's a big deal, but it's driving me crazy. This was not the crystal clear picture I was expecting. Having never owned an led tv before I don't know if this is normal? Can it be fixed with picture adjustments? Or do I have to find a friend that would be willing to haul it back to the store to exchange it? Thank you in advance for your help!!
