The tube should be ok its the IC's regulating the convergence is your problem . A tv repairman should be able to repair it fro around $250.00 - $300.00 or less depending on who you call. Good luck

Replace both convergence ICs nuber STK392-040 that should take care of the problem. you can get new replacement ICs at the following link and they will send free instalation instructions with pictures so you can install the new ICs. heres the link.
