re: Mounting TV to exterior brick question

I mounted mine above my fireplace in the brick but I could access the backside of the brick in the attic and was able to use unistrut to distribute the load across the bricks. It would be better if you could find the studs. The bricks are actually a facade on most houses, not structural like some very old structures were, so the possibility of them being pulled down by the weight of the TV plus mounting hardware does exist but I do not think it is that likely if mounted correctly. I would suggest not mounting in the mortar, that is structurally the weakest point.
