The speakers are wired, the subwoofer is placed in the right area, all the devices are connected and the receiver is still not working. The receiver is the brain of your entertainment system that controls how your components communicate and present your home theatre experience. When the receiver is not operating as required, the performance of your home theatre system. The problems can range from the display functioning abnormally to commands not being executed correctly. When all the troubleshooting attempts have been exhausted and the Denon receiver is still an issue, the microprocessor needs to be reset to factory defaults.
Write down your settings before proceeding with the reset as all your settings and commands stored in the system will be deleted. Some Denon receivers control multiple audio and video zones or rooms, and the necessary settings can be very complex. If your system was originally set up by a professional installer, contact them first to get the necessary settings.
Turn off the power of the Denon receiver using the "Power" button on the front of the panel. There is no need to disconnect the speakers or devices from the receiver. If the power is turned off using the remote control, the unit is in standby mode and not completely powered off. Ensure the display and all lights are off to ensure device is fully powered off.
Press the "Power" button while simultaneously pressing "Standard" and "DSP Simulation" on the front panel of your Denon receiver. These buttons may also be hidden under a flip panel depending on the design and model of Denon being used. Some Denon models require different button combinations to be pressed simultaneously while pressing the "Power" button, such as the "Surround Mode" buttons. Some Denon receiver models will not provide the reset instructions in the user's manual; to find the right button combinations you must contact Denon.
Once the display starts flashing at about 1-second intervals, then release the two buttons. If the display does not flash at the interval of about 1 second or does not flash at all, then repeat the previous steps. Power on the receiver and verify the reset is complete by checking the settings like the AM/FM presets, which should display generic radio stations. The user interface will walk you through a simple set-up to get your system back up and working.
