How do I hook up my new HDTV only using the coax cable?

My new HDTV (LCD) has no coax input. I get free cable from my apt complex and I don't want to HAVE to get a box (I'll only be here 2 months). Is there a way to convert the signal from the coax to any of the inputs on my TV? I know it won't be HDTV, but I just want a picture.
