I own a Sony 46" HDTV. I just moved houses and in packing up the set, the shelf that housed the center channel slipped off and banged into the back of the set. The speaker was not on the shelf, and the shelf just slipped off and hit the back of the set (glanced). I turned the set on and everything looks fine, and I also checked the convergence and it looks fine...but I was just wondering in general how resilient these things are. Could this bang have any long-term damage that I cannot notice today, or am I just being hyper-paranoid? Thanks.
