I had a similar problem develop with my JVC system. It is a CRT based rear projector and all of a sudden it started displaying everything with a really caustic looking green tint. It was especially noticable on the first Lord of the Rings movie, when they were in the mines of Moria. Anyhow, JVC sent one of their techs out to look at it, but I was conveniently not at home and my landlord let him in to sort it out so I cant really tell you what my issue was. The service manager that sent the tech out did tell me that they had seen a few instances of this happening with similar models to mine and that it was the projector housing, although I do not think she was using the correct terminology. Anyhow, they came out and that problem got sorted. Now it is starting to develop some issues with black reproductions. I was about to chuck this one in and upgrade it for one of their new D-ila units, but they only make those for the US market right now, and I am still here in Germany (want a muti-system).
