    Sounds like it may need degaussing. Power off at the mains for 15 minutes then power back on.

    Discolouration is caused by earths magnetism. Degaussing demagnetises the the TV.

    Do you have any speakers near the TV? Computer and home cinema speakers are normally magnetically shielded (cheap ones might not be), but HiFi speakers are not. The field from the speakers can magnetise the shadow mask/aperture grille, causing the electron beam from the guns to hit the wrong phosphor on the tube. This causes wierd colour "stains".

    As Kendo said, degaussing is normally the answer. Cycling the power a few times should do the trick.

    Cheers
