Thanks for the info guys. I checked over at AVSForums.com, alot of people mount there plasmas above their fireplace. I also checked with a local dealer who has setup 50 or so, right above fireplaces. He said he hasn't had any problems or had to replace any of them. He mostly sells Sony.
I'm thinking of putting a 42" above the fireplace for the living room and building a HT in the basement. I think this may work out better then trying to squeeze all that stereo stuff in my living room. I had made a post trying to do to much in my oddly shaped living room.
