Panasonic TH50PX25UP Plasma Picture Issues

Hi Everyone,

I purchased a 50 inch plasma from Panasonic last year and am encountering picture display issues. When i play my DVD's, there is a black bar that appears on the right side of my TV. What could be the cause of this? My HDTV channels are perfect. However, when i switch to my regular cable channels, there is more of a red overtone that apperas on the screen. The DVD also has this red overtone. You can see it on the faces of folks in the movies.

I have switched out my S-Cables, switched DVD players, switched inputs, etc. but cannot figure out what could be wrong. I'm not the most technical guy in the world but I'm not a novice either. Has anyone experienced such an issue?
