You can try to initialize the receiver back to factory settings. Note this will erase all the user settings. Most Denon car receivers have a small recessed reset button about 1/16″ in diameter (1.5mm) on the front panel. You may have to hunt for it. Gently press this button with ball point pen. If initialization does not help, the unit will need repair .
