Sony 36XBR450 Problem

My Sony 36XBR450 TV is nine years old and has never had any problems, but now it seems to be losing the color of red. The grayscale, which I had adjusted in the service menu years ago, is now starting to look bluish green. Is the picture tube wearing out? Is the red gun wearing out? I thought that if one of the color guns went out you would lose that color completely, but there is still red in the picture, just noticeably less than before. I can make the grayscale better by adjusting the red drive and cutoff up and the blue and green down, but I can't get the same grayscale as before. The picture is otherwise as bright and sharp as ever.

Try turning the red up more in the service menu.
