DVD player hook-up problem

Question

I have a TruTech T600-D DVD/CD Player. I am trying to connect it to my Emerson tv. I had it hooked up and working fine, then I moved to another state. I tried to hook it up again exactly how I had it before and now it won't work. I hooked it up using the Composite connection but got nothing. I also tried calling the technical support number for the company, but could not actually talk to anyone. Any help would be GREATLY appreciated!
