What are you talking about? The stand for the 65" C9 weighs ~17lbs and the second piece weighs ~2.2lbs. According to the LG page, the difference is 19.1lbs. That's exactly correct.It's wrong for the 65" - the stand is 10lbs, not 20lbs.
(no I'm not weighing my TV, but I'm 100% certain the 55lb number on the LG page is correct.)
