I suspect it is a issue with the convergence IC chips
replacing the blue convergence IC would most likely solve the problem
see this page http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html
Suggest you replace them all.
If this kind of repair is outside your comfort zone I would suggest to take it to a repair man.
