NFT: Plasma TV advice about prepping wall + studs for wall mount

mattlawson : 7/29/2014 9:53 am
mounting this new TV above my fireplace, supposedly it will arrive by Friday. The replacement one from Dell and Pilot freight if you've been following along.

I've had the Monoprice thin adjustable bracket waiting for a while now. I've located the studs, i think I'll pickup one of those electronic stud finders though and check my ego. My dad suggested getting some 3/4" wood backer board to mount for additional support which i think is good advice, just wondering if it will sacrifice being tight to the wall and just wondering if it's necessary.

Has anyone else done this, if I know where the studs are is a backer board really necessary? And does the TV really stick out if you do it?

Any advice much appreciated. TV weights ~50 lbs.
If you located the studs

and attach the wallmount to them, you should be fine. Those monoprice mounts are pretty sturdy once put into place. I could pull myself off the floor when I mounted mine and I'm well over 200lbs.
I agree with scyber

I ran the bolts directly into the studs and that mount isn't going anywhere. I did the pull up check as well :)
I have a Panny 55 plasma mounted on the wall

into 2 studs with 2 lag bolts each. It isn't going anywhere.
I can't add much too your question but...  
nicky43 : 7/29/2014 9:59 am : link
You dad's idea is a very good one. These things are very heavy. Also consider this... Big Plasma TVs run hot enough to heat the room it is in. The wall running up from your fireplace can get very hot depending on the construction when using the fireplace.

Be carful in the winter not to cook your Plasma TV from the combined heat of the TV being on for a while and the fireplace running for long periods.

Good luck.
Stud finder is a good idea  
Fast Eddie : 7/29/2014 10:08 am : link
but you can find studs just by knocking on the wall. You will hear the difference when you hit a stud. Also you should drill a small test hole to assure your drilling into the stud. Wood will come out on the drill bit. I wouldn't worry about drilling a hole or two since the TV will cover the holes anyway. You can always just put some EZ Patch spackle into the hole if you want. If your into the studs the wall will come down before that TV will. Good luck
also make sure that the mount is graded for the size/weight

of the TV. I know it's obvious, but it can be overlooked.
Wooden studs right, not metal?  
jcn56 : 7/29/2014 10:12 am : link
A solid wooden stud should have no problem, I've seen the backing used where metal was in the wall.
mattlawson doesn't need a stud finer.  
Wuphat : 7/29/2014 10:13 am : link
He can just dowse for the studs.

its the only good place for you to mount it but mounting above a fireplace that you actually use in the winter time is not a great idea. Also depending on how your fireplace is set up the tv may be mounted ridiculously high because of the fireplace and you'll be hurting your neck just to watch the tv. A friend of mine has his tv above his fireplace and the damn thing is so high, no idea why he did it like that.

Above the fireplace is a very popular mount  
The Natural : 7/29/2014 10:28 am : link
If the room is too small then it may seem too high. As far as plasmas heating the room because they run hot, it's not true.

Enjoy your new TV....I've had a 55" Panny in the game room for about 6 years and the picture is still as beautiful as when it was new.
I have a 60" LG Plasma in my basement  
Bockman : 7/29/2014 10:33 am : link
wall mounted into the wooden studs. Rock solid after almost 2.5 years so far.

Stud finders are cheap at depot. A worthwile tool to have at home regardless.
i wouldn't do it above the fireplace  
UConn4523 : 7/29/2014 10:34 am : link
for safety as well as viewing angle. It may be the only option, but I'd try for another way. Nothing worse than paying all that money for a tv and having a shitty viewing angle that diminishes the experience.

Your TV should be as close to head on as possible without having to move your head.
on the fireplace...  
mattlawson : 7/29/2014 10:47 am : link
the way the room is laid out - it's really the only place it can go. it is a wood burning fireplace - we do use it. so I think mounting some kind of backer board for protection, added security, etc will be the way to go based on everything im hearing.

In other words, it doesn't matter what anyone here has suggested, I'm going to follow my Dad's advice.
Matt,  
Jon from PA : 7/29/2014 11:09 am : link
Nobody wastes Peter's time while he's... trying to waste time.
So let me get this right  
Fast Eddie : 7/29/2014 11:11 am : link
the backer board is going to be attached to the studs. So what additional security does that provide? At 3/4 inch your probably adding an additional 25 - 30 lbs to the load on the studs.
the only real reason  
MookGiants : 7/29/2014 11:15 am : link
to add the backer board would be if you werent going to hit studs. Otherwise I see no reason to do it

a full 2x4 has with the sheetrock in front about 4" of full bite you can get on that bracket with a bolt.How thick is the backer board going to be?1/2 inch? and inch? even a full 2x4 on the flat gives a full 2 1/2 inches less to mount to. I guarantee the instructions for that bracket say mount it into a stud.

The whole backer board thing is advice by someone who assumes you can't find the stud.It's an incorrect installation, and if a pro installer did it he'd get fired if you called the shop back and reported it. The only reason to do that was if there was no stud there.Even then I'd go with a big toggle (3/8) into the rock.
Sounds like a man who knows how to find one.

No soliciting.
definitely  
blue42 : 7/29/2014 1:14 pm : link
do the backerboard.The more rigid that is the better.
the backerboard  
MookGiants : 7/29/2014 1:16 pm : link
only is needed if you cant attach the mount to any studs, and that doesnt seem to be the case here. I think it would be a waste of time
BTW..  
blue42 : 7/29/2014 1:16 pm : link
I oversaw many pro installations at a major network using union shop labor. They always used backerboard.

More than likely because they were zoned for metal studs.
It has to do with using the fire place  
mattlawson : 7/29/2014 7:44 pm : link
Not just sturdiness
Put another way  
mattlawson : 7/29/2014 7:55 pm : link
Is there any thin insulation board I can use instead to deal with the hot fireplace issue?
Are you saying the wall above the fireplace  
Peter in Atlanta : 7/29/2014 8:32 pm : link
gets hot from the inside?
It's a possibility that heat could damage it, yes  
mattlawson : 7/29/2014 8:45 pm : link
I have not felt the wall in that area while a fire was burning to have 100% certainty that it gets hot enough to damage a tv.

But the question remains - will backer board help insulate and sturdy the insulation or is this pretty much a waste of time barring incredible heat issues... In which case I should drill into the studs
if the wall above the fireplace gets hot from the inside  
oghwga : 7/29/2014 9:30 pm : link
then your house will burn down sooner rather than later. there should be zero heat from the fireplace from the inside out.

There is lots of heat from the fire that radiates out and up, that is a different story.

You will know if you hit the studs and you should predrill into the studs because the screws will hold better and the wood won't split.

I use a 3/4" backer inside the wall when I have metal stud construction or studs that aren't placed properly for my installation needs, otherwise it is unnecessary. I assume you've already run an outlet up there.
wiring is a separate issue  
mattlawson : 7/29/2014 9:51 pm : link
two outlets on either side of the fireplace i can tap into. we're going to have recessed lighting done also at some point in that room so i might have them drop a box in from the ceiling while the crown molding is off. until then i have a cord i'm going to run for the time being.
i installed my tv in my living room  
CruzShip52 : 7/30/2014 12:37 pm : link
70inch on wall, was very easy

took about 20 minutes and ran wires through wall

next step, two tvs mounted in my basement

metal studs i believe

any tips for that?
