Take it to a qualified repair man, as your question suggests that you have neither the knowledge or more importantly the tools to fix this problem. However if I am wrong, you must get a circuit diagram. Circuit diagrams are hard to get and they are often very pricey. Do not attempt this job without a circuit diagram.

The red and blue convergence ICs are bad. Probably only the red one is bad, but you should change both to be sure the other doesn't go out the following week.

This sounds like your convergence circuit has failed. There are large convergence amp ic's that will need to be replace and this is not an easy repair and will most likely require a qualified service professional.
