Sharp CF30E50 30" TV

I have a sharp CF30E50 30" crt TV i was working on for a customer that came in with no Vertical sweep. Soldered it up. Replaced the vertical output chip. ESR'ed in circuit around the chip and did not find anything out of the ordinary. Worked fine for a couple of days and then it took out the vertical output chip again. Any ideas on what could cause this? It looked fine with no picture distortion or compression when it was working.

There were a run of Sharp tv`s that had a problem with the vertical ic overheating because of poor design . Ad more heat sink does work .
