Your problem is a bad main B+ capacitor. The right way to find this would be with a good ESR type capacitor meter. If you do not have an ESR cap. checker or do not know how to use a cap. checker. a local repair shop should be able to assist you in this repair at a decent price.

I looked up this model and found the following electolytic capacitors to be the most likely culprits within the pincushion circuit. Check these first. The starred one is the one I have replaced in the past to resolve this.
Sorry Ginko, but a convergence problem would have the curves down from the top and up from the bottom. The hourglass shape is a pincushion problem. This can be as simple as a bad capacitor in the pincushion circuit.
Could you please confirm the model number so I can look up the probable part?
