this sounds like a convergence loss... the most likely cause of this is what is known as stk's or convergenc ic(chips) have gone bad.. also it cound be the output resistors. most likely need replaced

try to reset the convergence on the TV if the convergence reset wont work, need to call a technician to check the color gun

Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)
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!
