The red yellow and white are for composite signal. If the new tv has red yellow and white cables, they need to connect to the composite output from the DVD. These may be available on an outlet type cover on the wall behind the tv, just connect the matching colors. The DVD should be connected to the back of the wall plate. Once you have the tv connected via those three cables, you need to use the menu on the tv remote to choose input and select composite. It can take a minute or so for the pic to show up. If the tv and the DVD both have HDMI input/output, you can use the HDMI cable, but you will have to get to the back of the DVD player to connect it.
