Well, I have two LED tvs from Samsung, one is of 28 and the other is of 40. The picture quality of both the television sets are amazing, I watch HD channels mostly. Sound quality is ok, I don’t expect a very good sound quality from flat panel tvs, I prefer to use a home-theatre for sound.
I have extended the warranty period by three years, it gives a peace of mind.
I have compared the picture quality with many other brands. Samsung provides one of the best picture and sound qualities.
