Can you mount our TCL 50" and smaller TV purchased 9/19/18 at Best Buy on the wall? It's a regular sheetrocked wall in Aptos, CA.

I think 'The Geek Squad' handles that. Best to call them.

I think so.

Just f.y.i., if by chance you are renting your home, make sure you check your rental contract because some property management/owners prohibit renters from attaching anything heavy like TV's to walls. 🙄

I would use a track as well or mount the TV to the studs in the frame of the wall

I would suppose they can, but in the event they don't you can use Tackl or Home advisor services to get someone certified and low cost as well.
