A:AnswerYou have to change the input in the TV to the DVD Player for the signals to be displayed. Since the TV shows are appearing, the TV is tuned to the Comcast input. Using the TV Remote, first change the input to the DVD Player input and then start playing discs in it.
A:AnswerOn your universal remote it is vid 3. Sony is no help what so ever. When I tried to hook up my Sony DVD player. I went on line and put the model # in the back of their diagram did not match my back of the DVD player. I had in and out. I only had out plug holes. Called and still waiting for them to get back to me that was 3 weeks ago. I finally got it to work it took me hours. I have Directv and I didn't want to unplug anything and lose Directv.
