I have noticed that the top and bottom displays are out of focus. This is real evident while watching sports or something that shows scores, weather, etc. in the upper or lower 2" of the screen. Now I see images in the backgound out of focus that may be 3" in from the top? Confirmed with the kids and they notice it too so it's not just my glasses. It this an easy fix, or is it better to dump it and get a new one?
