My set is 10 yrs old. In the upper left and lower

Try adjusting the convergence. If it won't move see below- red IC in particular
This sounds like 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!
