I have had my DEH-P8400MP FOR ALMOST TWO YEARS. IT IS THE HU WITH THE MOTORIZED DECK THAT LOWERS DOWN AND THE DISLPAY BECOMES VEIWABLE. WHEN I TURN ON MY CAR, THE DECK LOWERS BUT THEN THE DISPLAY DOES NOT COME ON AND I CANT GET IT TO WORK. I TRIED EVERYTHING AND STILL IT WILL NOT TURN ON. I NEED SOME SUGGESTIONS. I PULLED IT OUT FROM MY DASH AND THE WIRES LOOK FINE. IT JUST TURNS OFF AS SOON AS THE DECK LOWERS . PLEASE HELP ME. BRIAN
