I recently bought a 51" Magnavox Projection HD Ready Tv from Walmart. Turned out it had a problem with games on HD and lines on the screen would flicker. Over the weekend I took it back, upgraded to an RCA 52" and the flicker is gone, the picture is much better than the Magnavox. But still have a couple problems. All text on the screen is blurred by what appears to be a double image of all text in blue that makes it appear the the words are out of focus. and the the right side of the screen is acturally blurry, does not focus like the rest of the screen. Oh well, will get the 4 year warranty from Best Buy and have them come out and fix or replace it.
