It is probably a convergence problem. Your TV does not have "bulbs" but 3 CRTs which are focused on the screen. Alignment is critical. If this goes out you see 3 separate colour images.

I think your set has a feature called perfect focus? This is supposed to align
the colours automatically using sensors around the screen. Sometimes it goes wrong and the results go way off.
Try the perfect focus again when the set it cold and when it has warmed up. It might just come right. If it does switch off the automatic setting so it does not go off again!
If you can do a manual convergence even better.

Do a search on these forums for this problem and learn a bit about it.

It may be a case of adjustment or some chips may need to be replaced. The latter will cost a bit!
