I have a Panasonic PT-50LC13, and had an authorized repair center change my lamp. After that, it seems I cannot view movies in widescreen anymore, they show up as letterbox. Same movies that I was able to view at 16:9 aspect once. My DVD connects through the component video connections and is already setup at 16:9. Interesting part is when viewing the menu, it shows up in full screen 16:9 ratio but when the movie starts playing it shows up in letterbox format. A little annoying considering it didn't happen before. I would appreciate any suggestions anyone can offer.
