Could be a bad headphone jack. There was a commong problem with denon receivers around that time where the headphone jack had contacts that would short and make the unit act like there were headphone plugged in even when there wasn't. Sometimes you can clear the error by inserting a headphone plug and unplugging it a couple times. If it continues to happen, then you can get the headphone jack replaced.
