This mount worked great on my Sharp Aquos 46" LCD.  
I did run into one issue, and that is that the tv is too tall to adjust the bottom two allen head bolts.  I can't remember if the allen wrench came with the tv, or if it came with the mount.  Either way, I just didn't tighten those two - the tv is heavy enough to keep it from sliding side to side which is what the bottom two bolts are for anyways.
