It is most likely the convergence panel. do your speakers make a thumping sound? if not, disregard this solution. change the stk392-110 convergence amps located behind the front cover on the convergence board. also check the resistors, it seems like they always take out two or more resistors. make sure all of your solder connections are good and none of them are touching. also, when you get the set back on you will need to manually adjust the convergence from the menu. you will need the factory remote. if you find bad resistors, the values are on them, but if you need the values and wattage, then use this page:

hope this helps you.
