Hitachi TV repair
Hello... Rear Projection TVs are not easy to work on. That being said, color issues can be caused by several different things. The most common involves the CRTs (there are three small picture tubes). There is a fluid in each tube that over time can dis-color, and involves a very difficult procedure to fix. Next, there are convergence circuits for each CRT, and one or more can fail. This will not usually cause the symptom you are describing, it will usually cause a double image in some or all areas of the screen and some areas the colors will look fine while other areas will not. It could also be a bad CRT drive board, or the video processing IC. It could even be the high voltage splitter! If I were you, I'd consider a new TV (please get the extended warranty). I hope this helps...
