Few days back while watching Tv suddenly I noticed a change in the picture size. I changed the channel and it remained the same .The problem is horizontal picture size of my Tv , it has shrinked. The vertical size is fine.
Instead of flat ,straight picture ,it turned to be curved one. It happened frequently and I already had a guess about the culprit.
I removed the Back cover of my Tv and removed the Main IC VCT 4964F PZF100 carefully by desoldering .
Now I replaced it with new one , and checked for any other fault. Now I switched on the Tv It works fine .
