I have a Toshiba TN55X81 tv and the screen is pink
These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.
When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
Convergence problems are very common on all Projection TV sets including Sony ,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer , Hitachi, Zenith, and others. You can get a convergence repair kit with instructions from the links below.
Hope this will help in solving the problem,,,,,
