My wife and I recently purchased an old farmhouse and one of the many tasks ahead of me is mounting the TV. We have a 40lbs, 55" flat screen and we've determined that the best place for it to go is int he corner of the room. One wall on that corner is brick and has a window near the corner, so that isn't the ideal place for the mounting bracket. The other wall is covered in old barnwood (vertical planks). Doing some poking around, it looks like the barnwood is around 1/2"-3/4" and is relatively soft. It is mounted via furring strips attached to 2x4 framing using nails (into the furring strips) around 4' off the ground. The top of the barnwood is tucked in behind a beam that supports the ceiling. Unfortunately, I can't really find where the studs are (I can see a few at the other end of the wall) and there were enough shortcuts taken in the construction that I don't trust them to be EXACTLY 16" on center across the length of the wall to allow me to drill with confidence.
My thought was to use a number of stout toggle bolts to hold the mounting bracket onto the barnwood. But my other concern is that since the TV will be mounted on the wall, but situated in the corner, the mounting bracket will be fully extended (meaning the maximum amount of force being put on it).
Does this seems like a reasonable approach? I really don't want to wake up to a crash in the middle of the night with my TV and half my wall in pieces on the floor.
