As you can see from the above answers, four CIMs are an overkill for this project as you don't need to raise the TV that quickly. We typically are raising devices on a TV set at much less than one foot per sec and typically the height of the TV (30-40 inches) in about 15 seconds. Any faster and the support hardware and structure take too much of a beating when you stop. The garage door opener motor in the link that Sanddrag has given above looks like a pretty good start. Remember that the motor is designed to lift a balanced garage door so it is likely producing the required lift for you project. It might even have all the needed end limit switches that you should use in your project.

Al has some great advice here.

I've spent a lot of time crawling surplus sites (usually for 540 sized motors), there are a lot of cheap, slow, torquey motors out there. What's nice about that is you really don't have to do much, or possibly no, gear reduction, and depending on what you buy, they could have a nice low efficiency worm gear to hold it in place.
