I have a 51.8lb Sharp Aquos LC46D85U that I'd like to mount above my fireplace.
The problem is that there aren't any studs (at least none that I can find) behind my wood walls. My walls are not wood paneling; they're solid tongue-in-groove wood (see picture).
The only structure I can find behind the walls is a few horizontal bars of wood at intervals. The wood walls are nailed into these horizontal braces. The intervals are too widely spaced for me to get all mounting bracket screws into them. I could get either the top or bottom mounting screws into them, but not both.
Given that the walls are wood (not just paneling), do you think they would be able to bear a 52lb TV mounted to it? If not, how should I safely mount my TV given my lack of studs?
