Mounting Plasmas on Plasterboard Walls....

Stokesey · 09-06-2005, 5:32 PM

Is there a right and wrong way of mounting a Plasma onto a plasterboard wall? I have used the 'Heavy Duty Hollow-Wall Anchor' these are the ones that open up behind the plasterboard. I have used 8 of these to hold the plasma and it appears to be very solid. I really don't see any other option as the walls are 'dot and dab' i.e the plaster board is stuck to the breeze block using dabs of cement (or whatever it is) this gave me problems when chasing the cables through the wall as when you hit the dabs of cement it was difficult to get all the cables through!! It has been up a week or so now and no movement so I am starting to sleep easy at night!!

I have the Panasonic PV500 and it weighs about 49KG I think.

do a search and you should find plenty of posts regarding this very subject. I think those with D&D plasterboard walls have mounted to the breezeblock behind IIRC.

How much gap is there between the plasterboard and the wall?

I would have thought if the plasterboard was only attached using the dot and dab method that you could have drilled into the bricks behind for extra strength if you were really worried and then used brick rawl plus

I'm in the same position

My new Plasma arrives tomorrow and i'm fixing it to a pretty hollow sounding wall.

I am in the same position, I am cutting out the plaster board where the mount is going to be and then drilling it straight in to the wall.
This way is sticks out a little less and you get a firm hold...

Well if it is a stud partition wall then use the metal rawl plugs that are specially for plasterboard and come with their own screws.

Otherwise drill into the wall behind and use the long heavy duty rawl plugs and at least 50mm no8 screws.

At the end of the day if you have a look at your kitchen units, think how much weight is generally in them and then realise they are probably fitted using simple fixings then you may sleep a little easier!!

You see hundreds of plasmas on light weight walls at AV Exhibitions so not too much to worry about...if you use 8 or so of the correct fixings there isn't a massive amount to worry about

This thread may help Panasonic TH42PV500 WAL (installed) + other kit some time soon...

The safest way is not to bother with the hollow spring anchor bolts but to
attach a sheet of MDF to the wall, as it has less chance of sagging/shearing
compared to plasterboard.

Them get 120mm bolts through the MDF, thru the plaster, thru the void then
well into the brick behind that. 50% of the bolt to be in brick as a good guide.
I had some B&Q bolts which are for windows and doors (lovely and long) with
special long rawlplugs...I used 6 thru the MDF and 4 more to hold the mount
so not a lot is going to shift 10 bolts in all!!

I wouldnt trust plasterboard to hold all the waight for a £1500 product....No way!

I used these anchor bolts from B&Q for my plasma install. I've got the same type of walls as you. The hole is drilled through the plasterboard and into the thermalite block behind. As the bolt is tightened the anchor expands into the block & with 6 of them holding up the mount, it's going to take a JCB to pull it off the wall.

See this thread for a few pics.

Wyerd, that is a nice job, this is a link to mine: http://img48.echo.cx/img48/8850/1161632img2ni.jpg
However I think I have made a couple of mistakes!!
1. Run the power cable with all the other cables.
2. not put any of the cables into trunking and plastered straight over them.
Questions for you if you don't mind:
What did you use for your channelling out of the wall?
What did you use for the socket where your cables exit?

Thanks in advance.

Used metal rawplugs on plasterboard. Absolutely fine.

I ran the power cables separately has they can cause interference in A/V cables

I used trunking so that it's easier to add/replace cables at a later date.

Your front l&r speakers look like they're much too far from the screen

Stokesey · 10-06-2005, 12:53 PM

Does it make that much difference, they could be easily moved if the difference is that noticeable?
Wyerd are your walls dot and dab?

Yes they are. I used a saw - can't remember the exact name - to cut the plasterboard first, but I had to go deeper in the blocks, which I used a chisel.

Dar Kaus · 24-11-2005, 10:00 AM

I too am about to wall mount my Pioneer 506XDE to a plasterboard 'dot & dab' wall the cavity behind is about the width of a hand, I also had problems with trying to feed the cables down the cavity, in the end I have had to settle for channeling out and using trunking as it was the only way in the end, lucky i'm re-decorating at the moment, my display has yet to arrive ( special order item ) but i have the three cables needed now installed awaiting the final mounting, so my question is does anyone have a 506XDE that can tell me at what position on the rear of the panel will the mounting bracket fix on to it, the reason I ask is so I can pre mount the bracket on the wall ready for hooking on the display, the problem is the same as knowing where to stick a nail in the wall if you want to mount a picture at just the right hight, can anyone assist me with this problem?
