If you are talking wood backing inside the wall use a stud finder and go around the area where it is supposed to be located. I guess it would depend on the size that would have been installed as an extra. I know in my trailer there is a sticker on the wall that say's mount here. A 16" LCD TV can't weight that much. I have a 32" and it only has 4 screws in it holding the bracket up.
