For ordinary people, it looks like an easy job to install the TV Wall Mount, just find the wood stud, and screw the TV mount onto the wall, so easy. But if you want to safely install it, it would be not a simple job. Frequently, I was asked to help the customer to finish their installation job that they could not fulfill by themselves, mostly, I have to reinstall it, left more holes in the wall. Sometimes, I even could remove the TV from the wall without any tools. In fact, if you have more knowledge about the wall and the installation, you will never decide to do it by yourselves.
Firstly, you even can not find the right center of the wood stud, especially in the cold or wet winter, even you use the instruments like the Stud Finder. Even it tells you something under the plasterboard of the wall, are you sure it exactly is the wood stud, not a pipeline or anything else?
Secondly, you should have the knowledge that there are many things inside the wall, just behind the plasterboard of the wall, like water&gas pipelines, live wires, landline&network cables, air conditioner pipes......, much worse, they may be covered or hided in the heat insulation cottons in the wall where you want to install the TV Wall mount. Take these into account, it is a quite challenging work to discover where they are located and how to avoid it, because they are covered by plaster board and heat insulation cotton, you may accidentally damage them when screwing or drilling and it is dangerous for you and your property.
Thirdly, you should have the knowledge to select the right TV wall mount based on the wall which you are going to install your TV, the internal structure of the wall, the frame of the wood stud, the size and the weight of your TV, the position where the TV is mounted.......
If you can not install your TV properly, you may hurt yourself,or damage your TV during installation.If the TV Wall Bracket is poor quality, the TV may fall down from the wall. If you are clear all these that I have tell you, are you still feel confidence to do it by yourselves. The reality is most people even do not know how to safely take the new TV out of the packaging box, especially for the bigger TV.
