Have had my Hitachi Rear Projection TV Serviced 4 times in 3 years. Same problem every time, pickture is green with a little blue. All they do is hammer on the Blue Picture Tube with a pair of plyers and make a few adjustments. 6 months later, same thing. Bought the extended warranty from Circuit City and it is about to run out. They will not honor the no-lemon portion of the agreement - for an other forum - what can it be and what can I do?
