Who was they? Sounds a bit suspect to me.
Stray magnetic fields from speaker etc cause discoloured areas because
the electron beams been bent and go thru the wrong hole in the shadow
mask. It is fixed by deGaussing. (and moving whatever is causing the
magnetic noise further away from the monitor).
This is a volatage problem I think, the electron beams are not being
bent far enough horizontally.
