Jerry, I would suggest a reset of the unit to clear this as it seems to be reading that the headphone input is being engaged. To reset the unit hold down the CBL button on the far right of the receiver. While holding that button down press the ON/STANDBY button on the top left of the receiver. It should say CLEAR in the screen of the receiver which indicates that you have done the reset correctly. The unit will then turn itself. Give it about a minute then turn it back on. If the headphone is still engaged then the unit would have to be returned if still within the return policy of the dealer. Thanks, FJD
