A TV lift is designed to raise and lower a TV upon command. The lift motor must be properly calibrated for the weight of the TV or it will not perform smoothly. To fix a TV lift that is behaving in an irregular manner, adjust the lift motor. The procedure requires use of household tools and does not require the technician who originally installed the lift.
Unplug the TV lift's power cord from the outlet. Remove the TV from the TV lift's platform and place it aside. Open the doors so that you can access the lift's motor inside the cabinet it is residing in.
