I have a Panasonic HDTV #PT-53WX42. We moved recently and now the TV picture is crooked. The picture is now higher on the left and lower on the right. When I try to adjust the convergence the lines won't match up with the notches on the side of the TV. The line is above the notch on the left and lower than the notch on the right. You get the idea. What can I do about this? Thanks Tom.
