How can I mount a TV when I can’t find studs inside my wall?
I am looking for some opinions here. When my electrician tried to mount my 80"TV above my fireplace, he found out there's actually only 1 stud available for him to do the mounting, he told me I need to retrofit the wall to increase the stud by 2, otherwise I can't do the work. However, according to my contractor, the TV can be easily mounted with only 1 stud, all I need to do is to bolt a rectangular piece of plywood (the size of my TV mount) to the stud and then mount the TV mount on top of it. According to him, he'll also nail the rest of the corners to the sheet rock and he thinks it's fine.
My electrician disagrees with him and I am completely puzzled. Any opinions here?
