I bought a 32 inch flat screen (not panel) at Wal Mart in November. After I got it home, the upper left corner of the screen had a yellow tint in the picture. I had it replaced at Wal Mart. Now the replacement has purple shading on the right side of the screen (about the right 20 percent of the screen). Watching a basketball game with a red painted court, you can notice it because as the screen pans to the right, the lane turns from a darker shade of red to a lighter shade.
