There is always a constant 5v for the device to go to standby.and power on when you press the power button .
This flashing is not to reset the device it shows that there is a problem with power supply.
the regulators are burned or over voltage ...
it needs service .
hope this helps

1. How to Reset Denon Receivers
   • 1 Save the information currently stored in your Denon receiver, such as device commands and multi-zone controls. Some Denon receivers can control multiple rooms and each room needs to be setup properly to provide the correct controls. If the receiver was installed professionally it may be best to contact the installer before resetting the device.
     
   • 2 Press the "Power" button or the "On/ Standby" button to shut off the receiver. On some receivers it is best to press the button on the device instead of the remote as the remote will normally put the receiver in standby mode. Ensure the display and all other lights on the device are off. Do not unplug the Denon receiver as it will not reset.
     
   • 3 Press the "Power" button and at the same time press two buttons on the front panel, which are determined by the model Denon you own. Most receivers identify the two buttons inside the user's manual, while some older Denon receivers require you contact Denon for the right button combination. For example, some Denon models require the "Standard" and "DSP Simulation" buttons to be pressed simultaneously.
     
   • 4 The display will start flashing at about one second intervals. Release the two buttons. Turn on the receiver by pressing the "Power" or the "On/ Standby" button to verify the previous settings and saved radio stations have been erased. If the interface does not flash, the reset was not complete and needs to be re-done. Re-enter the previous settings to ensure there are no further issues with the receiver.
     

Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

Are you getting a standby light at all? Is it flashing? Do you here a click when you plug the unit in? If the answer is no to all of these then you blew a fuse. If you do have soome sort of standby light, then your set is in protect mode. More than likely for a blown channel. If no lights, but you ar egetting a click, you could have a bad transformer. Use a DVM and see if it is open or not. Good luck

If the information helped you out please give some me some ratings. Thanks

If there is no reaction at all on standby button, the receiver most likely has a problem with standby power supply or mcu. If you get flashing red standby light, there is a problem with one of the channels or main power supply. Either case you need to bring it to a reoair facility.

Try to reset the macroprocessor. Unplug the unit from AC, hold both buttons SPEAKER A and SPEAKER B and plug the cord in outlet. After display flashes several times release the buttons. No result? - repair shop.

i had the volume of the multi-zone tuned too high and was attenuating it in an external control box. Once i took the multi-zone volume down to -25db, the problem went way. My main zone was operating around -35db so did not have the problem.
