Until someone has actually diagnosed the problem, they can't know what the failure is, so they can't give you an exact quote, because it might need parts or it might not.

On my set, re-soldering the RGB board connector, and re-soldering the convergence board connector, solved the problems. The real issue was getting the set properly re-converged after the repairs. That took time and care to get it right.

On most rear projection CRT televisions (I'm assuming yours is also a CRT rear projector?), the job of re-converging everything without inducing a "wavy" distorted picture, that's a tricky process and takes an expert. Even a dedicated tinkerer like me, who did it for long hours over many months, couldn't get it as nice as a pro did it in about 3 hours of fast work.
