Wall mounting 32" TV on a cavity wall

rubyrara

I'm looking for some advice as to mounting a 32" LCD TV weighing 22kg onto a plasterboard wall. I have bought a swivel arm mount from John Lewis but it only has two mounting points and I'm worried about using rawl plugs and it all ending in tears.

Any advice greatly appreciated.

I can appreciate your problem .
Can you find the studs , put a piece of wood across , spread the weight.

You have to find the centre of the stud . I have just put my 32" on a wall but used a external wall . In the instuctions mine came with it says to use differant fittings if fitted to a stud wall not the ones that came with the wall mount as they were for brick .

you do not say if the wall is internal or external.

Assuming its external, have a google for Rigifix.

These are available in M8 or M6 sizes, the M8 claim to be able to hold up to 240kg shear weight each.......

available for under a tenner for a pack of six.

I have used them on a cavity wall into block, and the TV is still there 4 months later

Guessing its an internal stud wall.

We've got a 42" plasma on an internal stud wall. My husband found the joists in the wall and made sure the bracket was bolted on to them. TV has been up there for about a year now and hasn't fallen off yet!

With the wall being hollow, he cut a hole behind the TV, and another hole behind the shelving unit that holds a DVD player, Sky box, Wii and Xbox. All the cables between the devices and TV are in the wall and it looks really neat and tidy.

There might be some general advice in the TV insructions about mounting on wall types.
Stud walls often don't have the studs where you want them and it can be a kerfuffle sorting them out.

Ive got a samsung 32" using raw plugs, if the plug needs a 5.5-6mm drill bit, then drill a 5mm hole, bang the raw plug in with hammer, make sure you have a good plug and then screw in with the biggest screw the plug can hold, I wouldnt like the thought of a swivel one as after some time the screw could come loose, ive got a bracket on ebay £10 and works a treat.

I use these in plasterboard

(choose the size to suit the thickness of the plasterboard and the hole size in the bracket)
Wouldn't rely on just two though.

The vertical studs within your wall will probably be about 16" apart, locate them by lightly hammering a small nail into the wall, if the nail goes in easily then its hollow behind it, move across about an inch and try again, keep doing this until you hit something solid, this will be the first stud. Once its located you need to find its centre, so again tap the nail in either side of your hole until you again find it hollow, once you have the two outside edges of the stud then measure between them for its centre, from this measure over 16" and check for another stud, if its there ensure that its the centre by repeating the nail test.

The options now are dependent on what you want, if the bracket is large enough and with its screw holes in the right positions you can just screw it onto the wall where the studs are located, ensure you screw them into the centre each time. If the bracket isn't big enough to reach the studs you will need to bridge the gap either on the surface or by cutting open the wall and inserting a piece of plywood in there and fixing it onto the studs. Easiest method is just to get a small piece of plywood and screw it onto the surface with about 8 woodscrews and then screw the bracket onto it.

As your bracket is swivel type the pulling power of the tv's 22kg will increase greatly the further its swung out from the wall, ensuring that its well mounted and secured is paramount.

Well Wookey just repeated what i had hinted earlier, but did a much better job

The only thing I would do , forget about cutting the plasterboard , just screw the ply on the outside , most of the time it will be hidden by the tv.
Hiding all the cables in the wall , is essential , nothing looks worse than dangling cables.
