CONVERGENCE PROBLEM IN TOSHIBA 43H70 (by 2 users)

I HAVE A TOSHIBA 43H70 I BOUGHT IN 2001 AND THE RED AND BLUE ARE OFF ON THE RIGHT SIDE. I HAVE TRIED TO USE THE CONVERGENCE BOARD TO STRAIGHTEN BUT MY RED WILLNOT MOVE TOWARD THE BLUE OR GREEN. ON NUMBER 1,3,7 THEY ARE RIGHT BUT ON 2,8 THEY ARE ABOUT HALF WAY AND ON THE 3, 6,9 THEY ARE WAY OFF AND SLANTED DOWNWARD. THEY ARE OFF ABOUT 1/2 INCH. CAN YOU HELP ME DIAGNOSE WHAT IS WRONG WITH MY TV OR IS IT WORTH FIXING.

Have tries to fix the convergence the red on 3 6 9 will not line up at all, and on all other numbers the red is off. The blue works fine.
