The tv has a black box covering almost the entire screen...this only happens when the aspect is on Normal...but when I adjust the aspect to Zoom 1 or Zoom 2 the black box is not there...also when I hook up my Xbox (not my Xbox 360) it works fine on Normal (aspect)...when Xbox 360, the cable box, or the DVD player is being used, the tv puts the black box on the screen...ive tried plugging each device into each one of the inputs and it still won't let me view anything but Xbox in Normal aspect view.
