I have a Pioneer Elite Pro-119 rear-projection TV that I purchased used. It has worked fine for about 3 years. Yesterday I turned it on and have the red picture "pinching" on the bottom left and top right of the screen. The alignment is ok on the rest of the screen. The convergance adjustment in the menu does fix it. What is the possible problem? Can it be fixed without calling a service person? What is the rough price range for the repair? I appreciate any feedback. Thanks, GTAC
