Can I mount a 40 inch TV onto a plasterboard wall?
yes, you can mount it on a plasterboard wall, you just have to ensure that you are anchoring it into the studs, or else it will not be able to support the weight of the TV
Yes but like torie said be sure to find studs (not men) to fasten to the wall. Mounting hardware that comes With kit should give you instructions.
I would locate the stus and mount 2 boards running horizontally. Use a couple of 2 x 6's, that way you will have strength and a space between the back of the TV and the wall. I would lag bolt the 2 x 6's into the studs with at least a 3'' lag, 4 would be better. Put a large flat washer (biger is better) so the board will stay nice and tight. You can use a 1/4 or 5/16 lag. You won't be able to see the 2 x 6's once the TV is up.
It depends on what's behind the plasterboard, and if the TV is designed to be hung up like this. We wanted to do this with our flatscreen TV, so we got a mount to put it up like that. But the back of the TV didn't seem to have solid points to attach to. I called the manufacturer, and they said that if I tried to hang that model, it WOULD VOID THE WARRANTY. There was no safe way to hang that particular model. So - if you do have a TV that can be mounted on the wall, you need to find out what's behind the plasterboard. I have never been to the UK, so I don't know their building methods, so this may or may not be useful for you. If the house was built with standard wood framing, you need to find the studs. Go to a hardware store or home improvement store, and buy a stud finder. I've linked to one manufacturer below, but there are many. Once you find one, drill into the wall to be sure you are located on the stud. If you don't get wood or sawdust, but only plaster, you're in the wrong spot. Another way is to look at where electrical outlets are mounted. Those are usually nailed to the studs, so if you look on a vertical line just to the left or right of the outlets, you should find one. From that point, follow the directions on the rack or mount that you purchased.
ALWAYS make sure to hit studs!!!!!!!!!!!!!!! At least 4 screws. As soon as you stepped away, the plasterboard would fail miserably.
