Can a 42in LCD TV be put up onto a plasterboard wall with hollow wall anchors?

Question

I'm just about to put up a 42inch LCD Tv (28kg) onto a plasterboard wall, there aren't any convenient wood studs to put it onto, can I use Heavy duty hollow wall anchors to put the tv and bracket onto up on the wall? can the plasterboard take the weight?

Answer 1

NO! Wallboard can hardly hold a picture. You will have to cut out a small section of drywall and add some support.

Answer 2

Don't use hollow drywall anchors. For such a high load the plasterboard will fail at the fixings.

Hopefully the plasterboard wall you wish to attach too is not that dual layer plasterboard with a honeycomb paper interior that is commonly used as a non-load bearing partition in the UK and probably elsewhere in the world too.

Its not so much that the plasterboard can't support a 28kg load its more that its not easy to transfer that load so that it stays within the plasterboard core. Even if you manage to achieve that feat you then have to consider how to stabilise the plasterboard so that accidental damage shock and vibration don't compromise the load. Oh and did I mention that if anyone leans on the television all that force will be trying to tear those hollow fixings out of the plasterboard..

DON'T DO IT!

Check to make sure what type of wall you have , if you think the wall is plasterboard with brick behind it then you would simply drill through the plasterboard and fix onto the brick with rawlplugs . If it is an outside wall or a wall between you or a neighbours house it will have a brick or block wall behind the plasterboard. If it is an internal wall of stud partition construction ( which is plaster board on both sides fixed to a timber frame ) you will get a good fixing if you hit the wooden frame . Is Your bracket a fixed type where the tv is flat on the wall , or is it an arm which swings out. the latter may require real careful fixing as it puts more strain on the wall , if it is the first then a 32 inch tv ain't that heavy you know , and I would be happy using inter set fixings (they are metal With a bolt that when screwed up tight spreads the metal out and leaves a threaded fixing , the bolt can be removed and used for fixing the tv bracket . they are pretty damn srtong fixings . I used to use them for fixing storage heaters to walls and they were filled with bricks! never had one fall over ever . Remember if it is a fixed non armed Bracket once you have the tv on the wall most of the weight is pulling straight down vertically the wall not outward so your fixings dont take an incredible force. I have a 32 inch lcd tv so I know what weight it is and i wouldnt be worried if I used intersets on it as long as it wasnt an arm type bracket. good luck with it m8 enjoy the tv

Plasterboard Wall Anchors

Answer 5

Hi,

As many butterfly bolts as the TV casing allows, which spring open in the plasterboard cavity should be OK, as the weight of either two 14kg is not massive, and four seven kg points is not a problem

I would first tap the wall to find the dull thud of the supporting woodwork to establish where he noggins are, and pencil mark them.

If you are lucky, the more solid wood bits will tally with the mounting hole centres on the TV. Then you can drill small holes into the timber, and use as big as possible wood srews
Much better & safer.

You will need to make a decent sized hole in the plasterboard anyway, to feed the signal & power cables through
Feeding those neatly & internally back to mains & ariel / DVD sockets is a trickier task if you don't want wall mounted pvc trunking on show.

One small advantage of having thin platerboard internal walls is that they are easy to attack & repair.
I was stuck with mounting one above the fireplace, so had to remove several bricks and fit a fireproof tube through to the garage. Nightmare.

All the best with it, then

Answer 6

Absolutely not.
you need to strengthen the fixing point in the wall. Fitt a patress inside the wall by cutting a hole in the plasterboard and feeding a 50x25 batten into the void. Fill the hole when finished and make good the decoration

If you want to start a woodworking project, you need all the necessary information, including schematics, blueprints, materials lists, dimensions etc. That is where Teds Woodworking comes in. The plans are clearly drawn and there're step-by-step explainations of how the plan should be done and put together. Go here https://tr.im/QzmLp

There are several other sites whose collection of plans have the dimensions totally wrong without any indication of parts lists, material lists or the tools needed. If you're one of those people who have bought plans like this in the past, Teds Woodworking will change your perception.

Answer 8

Can be done you just need the right fixings

convert the Kn into KG

Fischer toggle clamp KD 3 holds a recommened maximum of 0.14 Kilonewton = 14.27 Kg force.

So 4 of those will easily hold 28kg.

Answer 9

Please forgive any assumed irreverence...NO!

BUT..... in a direct answer to any CAN I questions I always answer YES; and add; you may not be happy with the result.

Very recentlyI answered a similar Q and I posted a Link, to an aol handy man DIY site that offers advice regarding your Q.

42 inch seems to be extremely popular, and a viable size even in a smaller room. Have you not considered that bracketing should be at/in studs? I guess if you insist on attempting it; you might load the floor underneath with a bunch of pilows.

Answer 10

Ummm...HELL NO!! There is no way I would hang my 42" Aquos like you mentioned, unless you like throwing away over a grand on your new TV.

I would look for other mounting options, like the dual steel pole stand, which has a low profile, looks slick, and allows for verticle adjustment of mounted TVs.

Sanus and BDI are pretty sweet, just remember to keep your LCD within the vertical 30 degrees, or so, of your seated viewing plane.

Good luck, but don't go cheap.
