Ours will hesitate occasionally and I've found that pushing down on it and/or jiggling it back a forth while pulling the lever helps release it. We also swapped out the junk Furrion TV that came with a Samsung that's a little heavier and as a result sometime have to "help" the lift raise the last few inches.
Planning on pulling the fireplace out this spring so I can get to the lift and lubricate everything to see if that helps.
