After I got the measurements of the mount brackets to mark the holes and marked, I then used my stud finder, found some, marked them and made some pilot holes. It quickly became clear the newly added wall was made of metal studs. I have never mounted on metal studs but after some quick research I felt convinced that it wasn't much different, other than the recommended bit and toggle anchor being quite a bit bigger.
Now, to the issue. I wasn't looking to install the mount strictly into studs, it was like a 10 pound 30 inch tv but I was working with one of those giant mounts for 80"+ TV"s. I think one stud and a couple drywall anchors would've been sufficient though. the problem began when the whole wall seemed to have a thin sheet of metal throughout it because no matter where I drilled there was metal. My stud finder never detected any possible AC where I was drilling, and I triple, quadruple checked sometimes that there wasn't any electrical. So after a little bit the mount was up.
But there was a problem. Both of the outlets on the new wall now aren't working. Is it common, or possible, for stud finders not to detect AC lines, or miss them completely if they're running through conduit in the middle of these metal studs? And do some contractors build partition walls using metal sheets in between each metal stud, like a big thin metal sheet inside parallel to each of the outer plaster boards? Now a question of desperation(lol) before I have to admit defeat and confess a mistake happened caused by me. My understanding, which is limited, of partition walls is the source of power they use for the outlets on them typically come from circuits from the closest outlets of the adjoining walls. The electricians ran the power coming from the ceiling instead and then down through the middle of the partition, where they were aware a TV was going to be mounted on that wall(it's a small wall)right in the middle. Nobody told me this but i'm not sure that matters. Most important question. Are there other reasons these outlets might not be working? The guys who built the wall say the outlets worked before they left, so how would I know if I knicked a wire? I imagine something would spark, or Any help or thoughts are very appreciated. Thanks. 21
