Mounting a TV onto a wall is a way to provide viewing pleasure throughout a room without having to give up floor space to a large TV table or cabinet. However, plasterboard walls are lightweight in nature and are not made to carry the heavy load of the average large-scaled TV generally mounted in place. The wall studs behind the plasterboard though are more than capable of carrying the TV's heavy load. By mounting through the plasterboard and directly to the studs beneath, you use the structural strength of the room, rather than the light material of the plasterboard to bear the weight of the set.
Select an area of wall where you wish to install the TV. Use a stud finder to locate the studs behind the wall selection and mark the location of the studs with a piece of chalk.
Place a VESA compatible wall mount onto the wall over the marked studs so that the mounting holes of the mount are aligned with the studs. Use a pencil to place a mark through the mounting holes onto the plasterboard wall.
Attach the mounting bracket to the TV. Take the screws contained in the TV mount kit and thread them through the holes of the bracket into the holes in the TV rear. Tighten the screws using a Phillips screwdriver to hold the bracket in place.
Drill a series of anchoring holes through the plasterboard and into the studs in the wall beneath using an electric drill at the pencilled in locations. Clear any dust from the holes using a vacuum.
Hold the wall mount on the plasterboard wall with the mount holes aligned with the pilot holes. Attach the mount to the wall by threading the anchor screws through the mount holes and into the wall studs.
Raise the TV with the mounting bracket to the level of the wall mount and slide the bracket over the mount. For heavier televisions seek the aid of a helper for lifting. Attach the safety tabs to the wall mount and bracket, securing the TV in place.
Place a carpenter's level across the top of the TV and rotate the TV as necessary to level it out. Plug the power cord into the TV as well as any audio-video cables needed for viewing.
