I agree with Don, there is usually 1 or 2 cables/shoestring style rope to pull behind the tv. They usually are less then 10 inches long depending on the mount. Some ppl tuck them away so you cant see them. Pulling these cables/ropes allows the tv to tilt slightly and then you can lift it up. Hard part is sometimes you have to pull both ropes at the same time to lift up the tv. Some mounts are easier then others.
