Hello, I'm new to home theater, some excuse my ignorance. I just received my panny 53wx42. At first I thought the picture was marginal, and was wondering if I had my component cables connected correctly and if the signal coming from my RP82 was set to progressive. But after running through Avia, the TV looks great!. My question is on setting the Convergence 1. I noticed that the vertical green line will never line up with the reference arrows on the top and bottom of the TV. If the top arrow is lined up, the bottom one won't be, and vice versa. In other words, either the reference arrows are not lined up in the same vertical axis, or the green calibration line is not perfectly vertical. Has anyone else experienced this? Is there something wrong with my TV? Thanks!
