Hi,
I want to mount a smaller lcd tv which weighs around 12kg onto one of the
internal walls in our house. It is one of those strange internal walls made
up of a sandwich with a sheet of plasterboard on the outsides and a centre
made of a honeycomb structure. The TV mount unit is basically a thick steel
square plate with the 4 holes in the corners at 100mm spacing (just like a
standard vesa mount on the back of a tv).
Do you think that 4 of those hollow wall anchors would be strong enough to
hold the plate onto the wall ? It has a simple tilt adjustment so once fixed
up it would just be left in position and not pulled about.
Any advice would be welcomed or other ideas on how to fix it ?
Thanks

I would have thought that sleeve anchors[1] would be fine for a load
like that. Its probably quite close to the wall, so most of the load
will be in shear anyway.

I'd agree that this type of fixing should be fine. We have a couple of HiFi
speakers about 8Kg each. They're on wall brackets each held up by a couple
of this type of fixings on the sane sort of plasterboard and never had any
problem over a good many years. The centre of gravity would be quite a bit
further forward than the TV would be too.

Being a cheapskate, I use http://www.screwfix.com/prods/12229.at less than
half the price,

And instruct people not to try and adjust it once fitted.

I've put quite a few of these up & used exactly those fittings - easier to
pull a sailor off your sister than get one of them out.

Most replies here are saying that it's OK to use this fixing or that fixing,
but I've a feeling they're missing the (major) point in that they are fixing
to a plasterboard stud wall, and yours are not stud walls.

Your walls are built with two sheets of PB stood upright with basically a
giant eggbox keeping them apart, and no timber or metal struts are used for
rigidity.
A stud wall has (usually timber, but more recently, box aluminium) struts
running up and down and also across - this gives the wall much more
strength, and using PB fixings here is usually OK because each fixing will
generally be no more than 6 inches away from one or more of these
strengthening studs, meaning the sheet of PB being fixed to is firmly fixed
to something else and it cannot (easily) come apart - I would not fix
anything to these walls heavier than half a pound, and a 25lb TV is totally
out of the question.

That's exactly what we had in our previous house, Paramount partition board.
The speakers must have been there for about 20 years with no problems.

.... with a studs only 12 inches apart ?

Your speakers were 8kg? - his telly is 12kg and will probably get handled a
lot more than hi-fi speakers, cleaning, adjustments etc.

No, the studs are usually 16 inch centres, meaning that unless you fix
directly in the centre of studding, which is highly unlikely and you would
be seven inches away,(the studs are normally 2 inches) anywhere else at all
and you would be six inches or less from a studding.

Yes, but he has 4 screws for the TV and I had 2 screws for each 8Kg speaker.

Obviously it would be wise to confirm that the bracket feels secure enough
before entrusting it to the full load. If repeated handling has any effect
then it's likely to show up as a gradual loosening in time to take remedial
action. I think it's extremely unlikely that it would lead to catastrophic
failure.

Absolutely NOT if its CRT .. i've had issues into solid brock...

rip away part of the wall and put floor to ceiling studs, a plate
beteeen and add plasterbaord over: skim and re-paint..
Thanks

What's on the other side of the wall? I mounted an LCD TV on my bedroom
wall, on the other side is the airing cupboard, so I stuck a piece of wood
to the wall and screwed right through into that.

The other side is another room so this isn't really an option.

The telly (15" Sony CRT) in our bedroom is mounted on a bracket, that was
originally fastened just to the plasterboard. After a while I noticed
that the p'board was "ballooning" outwards round the bracket... I screwed
a piece of plywood to the studs and screwed the bracket to that, instead.

As other posters have observed this style fo wall doesn't have studs. If
they had I would have adjusted the TV mounting to line up with a stud at
least for 2 of the fixings.

I did think of gluing a piece of ply onto the wall behind the tv to reduce
the amount the plasterboard would warp, and having holes through the board
where the fixings go through to the wall, or fixing the board to the wall
with the anchor fixings in a few places plus gluing it, and then mounting
onto the board.
