Makes sure which connectors in back of the tv you are actually connected to some tvs have multiple connections for av as well as hdmi. For example if you hook the dvd to av1 then using the menu on the tv select av1 even though another setting on the menu says dvd you tv is not smart enought to auto select what you have hooked up. Now if you actually have a hook up in back that says dvd then hook the dvd player to that , that way when you hit dvd on the tv menu it should work.
