Yes, a TV can go on nearly any wall, but the anchor and the method change completely depending on what the wall is made of. Getting that wrong is how a TV ends up on the floor.
Drywall over wood studs
The most common wall in Santa Clarita and the valley. The mount bolts into the wood studs behind the drywall. Drywall alone never holds a TV, so the whole job is finding and hitting the framing.
Plaster and lath
Common in older homes in Newhall, Burbank and across the valley. There are still wood studs behind it, but the plaster is brittle, so it takes a slow pilot drill to avoid cracking the face and to reach the framing behind the lath.
Brick, stone and tile
Solid masonry holds a TV very well with the right bit and anchors, drilled cleanly so the face does not crack. This is the norm on fireplaces.
Concrete and block
Common in apartments and commercial buildings. Masonry anchors rated for the load hold a screen solidly.
Metal stud
Common in condos, offices and newer commercial walls. Metal stud is thinner than wood and a normal wood screw will not hold, so it needs a toggle system rated for the load or a ledger spanning two studs.
