32" Panasonic CRT tubes going / discolouration problem
My parents have a two year old Panasonic 32" telly, and the tubes seem to be going, get green stripe on the left and red patches in the right corners, can only be seen on light-ish pictures, but is quite bad.
Tried moving the speakers and no difference, so it must be the tubes????
Is this serviceable / repairable or will it need replacing?
It cost me almost a grand in late 2004......

Turns out that it wasn't a technical issue at all. My Dad had set the contrast to MAX!!!!! I have now adjusted the contrast, and all is good again! 
It was so simple it didn't occur to me to check that! Thanks for the reply Andy, cause that lead me on to some pretty good sites for future!
