Wall mounting a flat-panel TV saves floor space in a room, but seeing the wires hanging down the wall from the TV can make the room look disorganised and cluttered. By following these steps to route the wire through your wall, you will have a clean and clutter-free look with nothing showing on the wall except your television.
Remove the bolts from the mounting holes on the back of your TV. There will be four mounting holes, and the included bolts are specifically designed to cover the holes. You will not use these bolts to mount the TV to the wall. Some TVs have a plastic cap over the mounting holes instead of bolts. These caps can be removed with a screwdriver.
Attach the mounting bracket on the TV. Attach the wall portion of the bracket to the TV mounting section temporarily to get the measurements for where you will want to hang the TV. The two portions should be attached when you remove them from the box. Simply reattach them to each other in the manner that they were originally attached.
Measure the distance from the bottom of the wall bracket to the bottom of the TV panel.
Mark on the wall with a pencil where you want the bottom of the TV panel to be once it is mounted. Then, use the measurement from Step 3 to determine where to mount your bracket to the wall. You will use this measurement in reverse. Measure up from your pencil mark the same distance between the bottom of the bracket and the bottom of the TV.
Remove the wall portion of the bracket from the TV portion and mount the wall portion onto the wall. Drill guide holes for the bolts, then attach the bracket using a socket wrench or screwdriver. Follow the instructions that came with your bracket. Be sure to mount the bracket where there are studs in the wall to anchor the bracket and TV. Use a stud finder to help you determine the studs' locations.
Cut a hole in the wall just below the bracket to feed the wires through using your drill and utility knife. Be sure you know the diameter of the hole you need (the size will change depending on the number of things you are hooking up and how many cords you have) so that the hole is completely obstructed by the TV once it is hung. Some brackets come with pre-cut holes in them to use as a guide to cut the cable hole in the wall. Feed the cable directly through the bracket and the wall hole.
Cut another hole where the cables need to exit the wall. If you have a shelving unit below the TV for your equipment, such as a DVD player, cut the hole so that it is hidden behind the shelves.
Attach all necessary cables to the TV and feed them through the first hole you cut as you move the TV closer to the wall and mount it. You will need a friend to help you lift the TV and guide the cables. Once the TV is mounted onto the wall portion of the bracket, the cables should be visible through the second hole. Reach in with your finger and pull out the cables. If the cables met an obstruction in the wall, you may need to drill additional holes. For example, if you have a 2-by-4 wood stabiliser between two studs, you will have to drill through that to allow the cables to hang down to the second hole. This may require more holes in the drywall, depending on where the 2-by-4 is positioned.
