Question

I was given this TV and I don't have a owners manual or a remote for it. I am trying to hook up my DVD player, but I can't figure out how to get the TV into video mode. I have gone through the menu and didn't see it there. I put the TV on channel 3 and played a DVD and the screen didn't change at all. We do not have cable on this TV. We do have an antennae (rabbit ears) so we can get a couple of local channels. Any help would be greatly appreciated.Thank You.
