How can connect my DVD player to my old Panasonic cable TV?

I bought this TV and a DVD player from a goodwill, and I've been trying to hook it up ever since. It didn't come with a remote but both of the machines work fine. I was confused in setting it up, but there's only two Audio/Video ports on the tv instead of three. The DVD play has all three, but it's not showing up on the tv. There's no imput or display button on the tv so i don't know what to do??
