How to Build TV Lift Linear Actuator


A TV actuator is a box that causes a TV to rise and lower inside an object. Many people use this mounting system to hide the TV when not in use inside a shelf or other cabinet. When you want to watch TV, all you have to do is press a button to raise the TV out of the cabinet. You can make your own actuator system using basic carpentry and electric skills.

Things You'll Need

  • 2-by-4 planks
  • Measuring tape
  • Saw
  • "L" brackets
  • 2-inch screws
  • Power screwdriver
  • Guide rails
  • Universal TV bracket
  • DC linear actuator
  • +12VDC power adaptor
  • Remote control with receiver
  • Mounting brackets
  • Measure the height and length of your TV set. Build a box with 2-by-4 boards so that the inside measurement of the box is about an inch longer and higher than the measurement of the TV. Screw "L" brackets inside the box at each corner to add stability to the box.

  • Cut a piece of plywood equal to the measurement of the outside edge of the plank box. Screw the plywood to the box.

  • Screw guide rails to either side of the 2-by-4 box on the plywood-covered side. Make sure the guide rails are positioned the same distance apart as the TV bracket so that the bracket can slide up and down the rails.

  • Screw the TV bracket to the back of the TV using the enclosed screws.

  • Screw the actuator to the center of the plywood board. Mount the motor inside the plywood box and the rod in the center of the plywood board.

  • Mount the power receiver inside the plywood box. Attach the +12VDC on the power adaptor to the input line on the remote control receiver. Attach the ground wire to the power input line on the remote control receiver.

  • Connect the two wires in the actuator to the channel pair on the remote. These are usually white and blue wires.

  • Slide the TV in place onto the guide rails. Secure the plywood box to furniture, the wall or floor with mounting brackets. Plug the TV and actuator to the wall socket. Press the button on the remote to make the TV rise.
