IMHO TV's don't belong above a fireplace and to drill a brick fireplace to mount one is well.........But then it's your neck that will take the beating watching it.
+1 i just don't understand WHY people want to put them there. A fireplace is something you may need to use for survival during an emergency with a fire going for days. One day the TV will need replacing as well and replacement may use a different mount. Then figure wires and cables you need to run to the TV. And how about blu-ray players,cable box DVRS and whatever else ? Save yourself trouble now hang nice pictures over the fireplace and set TV up elsewhere.
