Projection TVs have a high intensity lamp as the light source. They wear out and gradually get dim. You probably need to replace it. Check the manual re how. Be warned, the price will floor you ... several hundred dollars.

Read the article at the link in case there is something you have not been doing that you can do to extend the lifetime of the replacement lamp.
