Anyway, if you did not have a wall mount type plasma, i recommend not to wall it because the table or stand type is most flexible to rearrange it in the future.

The first part of your question , the wall is soft because that type of wall is called Drywall -it a sort of combination of chalk and and other items combined together . but the the most important thing is the wood or metal framing in back of that drywall that is where you would screw or bolt on your mounting bracket, for most apartments the STUDS as it is referred to(wood/metal frame) general are about 16" apart in some places it could be only 12". OK when you do buy your TV with the brackets your sales associates should advise as to the width of the bracket you would need,.. another thing you can do is to go to a neighborhood hardware retailer like home depot or Lowe’s and buy a stud finder yes that is what they call it and then you would have a better idea of the wall measurement,……… back to the TV ounce you got that part completed you can start to look in your TV and the brand you like just off hand a stud finder might cost between 20.00-35.00 bucks all depends on. were you live and when you do buy tour TV all the mounting screws comes in the with all hardware included in the purchase and the directions in side the box with the diagram.

…sorry if these websites doesn’t help you..coz I think its not related to your question..about the soft wall..thing…

Hope it help you..=)

If you intend to wall mount your new TV , I would suggest you DON’T.

LCD screens are better to use for wall mounting as they are much lighter.

My advice would be that if you want the TV hanging from the wall you should take the Plasma back and exchange it for a LCD screen.
I would also get a different brand then LG.
Go with Samsung or Sony , much more reliable software inside the TV.

NOTE:
Don’t attempt to wall mount the TV yourself – they are not as easy to do as they are made out to be.
Get a Professional to do the job.

That’s what you screw the mounts into….and most walls have 16 inch distance between the studs, so I suggest going to your local lumberyard and purchasing a mid-priced studfinder to find the center of the stud and drill your hole into them.

Once you set your first hole, you measure 16 inches over, and drill another hole that is level to it….

Then you mount your wall bracket to the wall….

And while you are looking for wall brackets, you can find some with a built-in level….but you still need that stud-finder and have to set your first hole….then level it out with either the heavy wall bracket or the lighter level….

And if you cannot center it in your room because the studs aren’t centered in your viewing area, THEN you need to use WALL ANCHORS….

And if you do use wall anchors then you need them rated at 100 to 150 pounds carrying capacity….

And I do suggest reading the instructions for that information…and talking to the lumberyard guys.
