I have a toshiba big screen tv we believe both convergents need to be replaced we do not have 300-365.00 to repair it . I know how to solder can I do it myself???? model#57H81


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!
