convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

Convergence issues usually resolved by changing convergence output amplifier IC's.....Original STK392-110 should be replaced

One of your convergence IC's has burned out and needs to be replaced. A good rule here is to go ahead and replace both STK392-110 IC's with the new improved STK392-150's. If you have never replaced convergence IC's and realigned convergence circuits, allow a qualified tech to handle it for you.
