Dead LG 21inch Ultraslim Tv Repaired

The tv uses str w6556 as the switching ic.This ic is shorted,so I replaced it.Switching on the tv I discover that as the tv is about to raster the ic trip off .The ic was shorted again.Line transformers use to be a major problem of this tv so I concluded it is bad and went to buy another flyback tranformer.I fixed the transformer but what I saw when testing the tv is a small wavy picture on screen and the tv went off a few seconds and stayed in standby mode.As I was testing the components on the power supply I tested the power capacitor and to my suprise the capacitor is seriously bad though it looks okay judging from the look of the eye. I changed the capacitor and tv starts working again.
