If the TV has a USB port, check to see if the 5V line is switched.
I've done this a few times over the years... it's a simple and reliable solutions as long as you don't need to control the lift independently from TV power.
I found some 5v relays that had USB connectors which made it really easy. You'd need to add a 12v power supply to the relay.
