hello I have a GPX DVD player model # D200B. As I was setting up the DVD player on my Curtis Mathes TV set I somehow lost the "set-up" menu picture. I am able to get the picture to work ( regular tv stations) but when I go to the DVD function it goes back to the scrambled picture. I have tried everything to get back to the menu/set-up screen while using the GPX dvd player; Including un- plugging the DVD player for more than two hours. Please help!
