65' Inch Plasma Mounted on ONE Stud ?

Hey everyone, first time poster here so don't kill me if this is in the wrong section or I sound like an idiot. I did my research, but couldn't find anything on my particular situation.

So heres my conundrum. I'd like to use an articulating wall mount (that I already purchased) for my Panasonic Viera 65" VT50. The wall that I'm mounting this TV too is 63 inches wide, and the TV itself is approximately 59" wide <- I know, a little overkill, but I wanted a big TV and this is literally the only place that it can go.

My problem is, with how the studs are spaced (16") and the overall width of the wall, unless the articulating wall mount I use has a back plate or mounting plate that is 32-33" wide, I won't be able to have TV securely mounted to 2 studs <- which is ofcourse a no go. Not to mention, I've been looking for an articulating wall mount for a 65" TV with a 30'+ back plate and I can't find them anywhere, Yet I can find them that wide in the fixed - tilt only setup all day.

BUUUUUT, something I just discovered is that the way this one particular wall is setup is there is the 1/2 thick sheet of dry wall, then a 3/8 slab / plank / sheet of wood that spans the entire wall, and then the studs behind that ofcourse. So it goes Sheetrock, 3/8 slab of wood, then studs

Given that the TV weighs apprx 98lbs according to Panasonic, could I get away with two lag bolts (top and bottom) securing the TV mount to the one stud it can hit, and then use something else to secure the rest of the mount in multiple spots to the 3/8 thick slab off wood thats between the drywall and the studs? I can't help but think the 3/8 piece of wood could do the job if its being anchored into multiple times in multiple spots, and a decent part of the weight or strain is picked-up by the two lag bolts into the stud.

If the above can't work, then I'll simply have to go with the flat mount setup with the tilt option... unless anyone knows of a place that sells the articulating mount with a 30" back plate. Or I can always open up the wall..... which I would love to avoid at all costs.

Any thoughts ? And thanks in advance for any help or ideas you send my way

Wow, Really ?

And on the toggle bolts, were you just securing those to drywall, or did you have a large piece of plywood behind your drywall before the studs like mine ?

Thanks, I literally just stumbled across another thread that was suggesting to use the same thing. One thing I can't wrap my head around is how the toggler setup can supposedly hold more than twice the weight of the Moen setup, which appears to be a far beefier setup...

http://www.moen.com/securemount

The previous home owners had port holes to chase the HDMI cables etc through the wall at the top and bottom, so it was easy / clear to see the layer and thickness of the drywall as well as the plywood beneath it.

Apparently this sheet of plywood is something they did to all the "media walls" in the group of townhouses I live in.

And there isn't only one stud in this wall, but in order to achieve proper centered placement with a gigantic tv that takes up the entire wall, and the 16" spread between the studs, I would need a mount setup where the mounting or supporting back-plate that secures to the wall is 32" wide to reach from stud to stud due to how the studs are positioned. A back plate of 16-24" simply wont make it. After doing some research on the forum, this is apparently a pretty common problem with a tight tolerance setup like this

Unfortunately with the placement of the studs, their spacing, the lack of space i have to work with on the wall (about 1.5"-2" on each side), without a 32" backplate on the mount it just isn't possible.

The interesting thing is that the Co. that produces the Togglers, claim that their setup alone can work for an articulating mount-setup <- and thats not with the assumption that a bulk of the support is divided between lag bolts going into studs, and the togglers having plywood and not sheetrock to grab onto. I'm thinking if I do the Lags, the togglers, and torque everything down with a torque wrench so that everything is mounted with equal pressure/force and the weight is being distributed equally, I should be okay. Sounds like its time to put this theory to the test.

One thing I wish I could figureout is how close is too close to space the togglers, It can't bee good to have 20 1/2" toggler holes right in a row

And the only reason I want to use the articulating mount is so that I can angle the tv literally just an inch or two on the left side so that it flows with the connecting wall better. I never plan to actually pull this massive 65" beast a couple of feet form the wall like the mount allows.

Problem Solved.

I was using this type of mount setup.

This setup does not allow you to slide the entire tv over or offset it to one side of the mount. So the mount has to be centered on the wall if you want a balanced centered look for your TV location <- which was a problem for my specific application because when the mount was in the center of the wall, the closest stud lined up dead center in the middle of the mount. Which meant the next closest stud for securing the second mounting point was 16 inches to the left or right. So without a backplate that was 32" inches wide to reach two studs at one time due to my wall/stud setup in conjunction with using this type of mount, I had to look into backboards, togglers, etc


If you go with a mount like this from Sanus, http://www.sanus.com/us/en/products/visionmount/full-motion-mount/XF228
you can put the mounting plate off to one side of the wall (in my case so that I can hit two studs instead of one), and then snap in the arms and slide the TV counter to the offset mount so that the TV is centered perfectly on the wall. No need for togglers, moen anchors, back boards, tearing out drywall, or new studs.


Unfortunately this was just one of those instances of where I didn't know what I didn't know. And I simply had no clue such a mount existed. But with everyones help and muuuuuch browsing on the site,.. and calling stanus, I found exactly what I needed

Thanks again everybody !!!
