The tv no doubt experienced a surge which has caused a problem in the power/deflection circuits. this is better left to an experienced TV tech, unless your skilled with diagnosing electronics with high voltages that are normally present in the deflection circuits. let me know if you need further assistance.

First, repair convergence problem = replace both convergence
IC's ....STK392-110 sub to upgrade STK394-160E....I use
Hitachi part # CZ 01341.......next, look for discolored resistor
near IC's.....replace with exact value......last = activate
