Please Help -- Zenith Z27X74W Color Problem

Hello all. Our family has a Zenith Z27X74W 27" Traditional Console Model that
has started giving color problems. The Serial No. is 781-42431188 and it was
manufactured in October 1997. Our family has always bought Zenith's as far as a
living room television, although I'm a tried and true Panasonic fan for
everything, and it used to be, that Zenith's were very stout TV's, but this is
the second one in the 90's that we've bought, and we realize that they're junk
now. But anyhow, what's happening with it. It's a yellow tint most all the
time, unless something bright and blue comes on and then it seems too bluish.
Judging from what I've read on here, it seems like the common Zenith picture
tube failure warning signs, but I wanted to make sure by asking you all if you
knew what it was, and if there's any use in fixing it.

I would really appreciate any help you all could give. :-)

Thanks,
Tommy
