Man this seems like it’s getting overly complicated.


Update. The cabinet/shelving does not go completely to the ceiling but the drywall was sloped downward from the back wall to meet the front of the cabinet. So that makes finding wall stud above cabinet a no go. However the electrician is making cutouts to move gangboxes. I’ll be able to peak in and find the studs and see what I am working with. My plan is to hope for no surprises and that studs are right there and cabinet is flush to wall. Lag mount to studs, hang tv and call it a day.
