I mounted my 60” inch tv over my fireplace and a bulge has appeared on both sides in the last few days. I’ve done some searches and it sounds like this is a “nail or screw pop”. My question is this something I need to be concerned about? Can the tv come down because of this or rip the tv and mount off the wall? I used a stud finder and there’s 4 2 3/4 lag bolts into the studs but I just want to make sure the tv is safe. The tv covers the bulge/bubble so if the integrity of the mount is fine I don’t care. Any information or advice is greatly appreciated!!
