How can I find out where the input is to a coaxial outlet in the basement of my house?

Question

There are literally dozens of coaxial cables that have apparently been run all over my the house I just bought over the years (it's a big older house). I need to find how to tap into the coaxial cable that goes to my downstairs living room. I don't know how to figure it out other than to hook the outlet in that living room up to my tv and then haul a VCR into the attic and try hooking it up to all the loose ends until I find one that sends a picture to my tv. Is there some device (that's reasonably affordable) that you can accomplish this with or a trick you can think of?
