It's going into protect. Unhook ALL the speakers and see if it still shuts itself off. If so, then it will have to be taken in for service.

This is a very common problem with denon receivers of the 2001-2-3 vintage. On almost every one, there are 4 little "surge" resistors in the power supply. These werent quite robust enough from the factory and one day would just burn open for no reason. Well, actually there is a reason, the "surge" that happens every time you power the unit up eventually weakens the resistors and then they pop. You need to take this to a denon service shop as I GUARANTEE they have seen this before. They need to check resistors in the picture, locarde above the **** rectangular connector. Resistors numbers R141, 142, 148, 149: 75f69d7.jpg These resistors when measured, should be less than 10 ohms each. If they are more, then they are blown. If they are blown, then have the shop check the channels for blown output transistors. If the outputs are OK, then these resistors should be replaced with 1 ohm 1/2 watt metal -film flameproof resistors. You might need to be prepared for a large bill, because the entire unit must come apart to replace the resistors, however, just checking them takes only about 10 minutes... Good luck and don't try this at home. Rob

SOURCE: Denon AVR older receiver but worked fine; now

Did you try to reset the unit? Resetting the unit has fixed every problem I have ever had......turn off unit.....hold down A+B at the same time then turn the unit back on...hold buttons for roughly 3 seconds....Let me know if it works.

Blinking standby light on Denon


could be a couple things. Either a blown channel in the amp, or a bad voltage regulator. would have to investigate further with a meter to find out.

On/standby button is flashing and as soon as you push the on button it turns itself off


sounds like a short in the amp section. Will have to be taken in for repair

I have done some research about my denon arv-1601 reciever, narrowed it down to a ressistor problem, it turns on for 4 seconds and turns off and goes into standby mode. Any Suggestions?


Usually it is bad power supply problem or bad channel problem. Look for any burned parts, it helps you locate the problem. Burnt resistors in one channel- you need to replace output transistors (better to replace all transistors in that channel) and bunch other surrounding parts. If you do not see any burned parts, check all voltages coming from power supply +15 -15 +5 etc then check dc at every channel output (not at speaker terminals but at control pins on the amp/main pcb), should be +-10mV

When I turn the unit on, it turns off in a few seconds. There is a flashing standby light.


Power switch relay needs replaced. Its a small black box with a clear piece that comes off, it would be hard to replace yourself.

Denon AVR 1601 with no sound output


Sounds like Audio ouput ic's. They're located on the inside of the unit on the big heatsink. get the part number(s) of them and call you local electronics store for parts.

The unit is in protect mode. It has detected a problem in the final output stage and has shut down to prevent further damage. Disconnect the speakers completely and try turning it on. If you still get the same symptom, the problem is inside the unit and repair is required. Usually when this occurs, the output transistors have failed. There will be at least 2 that need to be replaced. Figure on parts costing around $15-$25. Add in the local labor rate for the complete repair cost.
