A band of color for a picture on my 50H72 toshiba projection tv suddenly becomes either half a picture with a thick band of color on top or just becomes a band of color with no seeable picture. We have also had the problem of a too red picture or negative picture which i thought was from the dvd player but apparently was not. What is the solution? jctypes

The most likely cause of a problem such as described is failure of the "Hyper Module"; this is one of the "stand-up" PCB's on the main signal PCB (which is the one on the right when viewed from back of set). These modules have a history of failure of the multiple electrolytic "surface-mount" capacitors; successful repair of hyper modules usually entails replacing all caps on the board, and often some solder repair as well...the degree of soldering expertise required to adequately service such products will usually preclude all but professional repair
