Question

I need help with this. I bought this tv a couple of years ago and I have now given it to my parents. Firstly I presume it is a digital tv? I bought this as a ex disply and I do not have an instruction manual with it. Do you know where I can get one? I tried to set it up and I got a few channels but no sound. However when I connected the dvd it had sound. Can you help with this?
