The first thing you need to do is to locate the studs along the wall on which you wish to install the flat panel TV brackets. Use a stud finder, also known as a stud detector or stud sensor, for the purpose as it will make the process of locating the two studs for supporting the TV extremely convenient.
Once you have located the studs, mark the location of each stud’s centre with a pencil. It is recommended to confirm that you have located a stud by using a nail.
Measure the distance between the holes on each TV mounting arm by holding the brackets up to the wall and then use a pencil to mark the holes, both top and bottom on each mounting arm, for where the bolts or screws will be going into the wall. To ensure that the mounting holes for each arm are even, use a level.
Now plug a power drill into a power source and start drilling pilot holes at the points you marked in the previous step for the bracket bolts or screws. This could create a bit of a mess on the floor, which is why it is recommended to spread a sheet or cloth on the floor right under the area of the wall that you are drilling. Be careful while using a power drill. To save yourself from being getting an electric shock, wear some rubber item, be it gloves or shoes. Also keep your fingers at a distance from the front of the power drill.
After you are done drilling the hole, attach the TV bracket plate to the wall by using the bolts or screws that came with the wall mount kit. Use a socket wrench to drive lag bolts into the wall if required.
