It is a protection because of a power supply malfunction or bad channel (most likely). Repair it at www.ebcelectronics.com

Red power light blinking on my denon avr 1907, tried reset procedure, no speakers hooked up now and it still goes from green light to blinking red light and shuts off...Any clues?


This is a protection mode. The receiver protection circuit detects an internal problem like missing power supply voltage or blown channel and shuts down the receiver. You need to bring the unit to a repair facility.

Denon AVR 2105 power shuts off, tried resetting the micro processor and no luck. Please help...


The receiver has an internal problem like bad power supply or burnt channel. You need to bring it to a local repair shop or mail it here.

I have an AVR 988 system that will only shut down manually. I have shut down the system, changed batteries in my remote. Neither solved the problem. Any ideas?


Its a common problem with this Denon model series 1508,1708,988 the trouble lies with the power supply voltage going low. Usually its either the 15 or -15 volt that goes low. If either voltage goes low it will trigger the protection circuit hence the unit will shut down.

Problem denon avr 1910


most electrical units have a fuse inside,try taking cover off and checking for blown fuse,or,take it to radio repair shop.My Harmon Kardon stopped after 3 years,and the report said the unit that failed was quite a common problem for the modern multi channel amps,quite cheap to fix..All my tips are free

Unit keeps shutting off


Protection circuit activating. Possibly a shorted amplifier channel or power supply fault. Take it to a Denon repairer

When I turn on my receiver, it automatically turns off and the power button flashes red. Prior to shut down, the receiver display notes "Tuner Ext. In" What's the problem? It has worked p


Protection circuit turns off the unit because of critical conditions- wrong power supply voltages or one of the power amplifier channels is bad. First, visual inspect the power amp board near the heat sink for burned resistors, test outputs for a short. If there are no problem you may try to turn the unit on and you have several second before it shuts down to check power supply voltages and power amp output voltages and bias, then ... Long story you'd better take it to a repair shop or repair at ebcelectronics.com

The power light keeps flashing orange


I had my Optiplex GX520 at work shut down abruptly every time I turned it on it in the morning. This would always happen within the first 30 minutes. I would then get the flashing amber light. After starting the PC again, it would stay on all day (over 8 hours) without shutting down again. I found that the power supply was over-heating.

Two things need to be done. First, in order to get the amber light to stop flashing, un-plug the computer from the wall for 30 seconds then plug it back in. OR hold down the power button for 10 seconds or so. The light should stop flashing. Then press the power button again and the PC should start.

But why did it abruptly shut down in the first place? The power supply has a fan-speed-control circuit in it to keep it running slow and quiet when the power supply is cool. It gives the power supply lower voltage when the power supply is cold and higher voltage as the power supply gets warmer. This circuit either is not working correctly or the fan getting sticky over the years and needing more voltage to get it moving when it is cold. I found that the fan was not starting at all and causing the power supply to over-heat.


To keep the fan moving at full speed, I cut the wire to it and wired it to the +12v output directly. Not the fan goes at full speed all the time. And yes, it is nosier. But at work it doesn’t matter.

The best solution would be to just get another power supply from Dell if possible. Or buy a +12v, 70mm fan from Digi-Key and replace the original.

My denon avr-a10se stop working. When I start, aftr thr quick intiation the amp shuts itself and the red power light start to blinvk quickly - please help


This unit is in protect mode. This means that a problem was detected in the last stage of the amplifier section and the unit shuts down to prevent further damage. The most common failure parts are the output transistors. These usually run between $5-$15 each. Add in the local labor rate for the total repair cost.

Shutdown protection? HELP please


All of the Denon recievers I have repaired (over 100) that shut down after a very short time are going into protect mode. The display lights up and after about 10 seconds the display goes out and the standby led blinks red.
I have found that they have one of 3 possible problems and they all require that the reciever be taken apart and fixed at component level. No way to tell what your problem is until it gets put on a bench and troubleshot.

Problem 1. This is the most common problem. One of the front channels shorts out. On the big heat sink the front channels are at each end. It is the front left channel (close to the display) This requires that the output transistors be replaced as well as some driver transistors and some resistors and a capacitor. Lots of work for a blown channel. Denon has put out a bullitin to upgrade the bias transistor and change a couple of resistors to help compensate for this failure. That channel overheats more than any other channel.

Problem 2. There is a resistor that is right next to the preamp board that opens up. It is a 10 ohm 1 watt resistor and when it opens, it causes the unit to go into protect.

Problem 3. The +12 volt regulator fails. It is in the power supply area on a smal heat sink right next to the -12 volt regulator. Generic part number is KIA7812 It also causes the unit to go into protect.

Most decent repair shops can fix these from about $120 up to about $200. Depending on which problem it is and how fast they are at finding the problem. Most charge labor by the hour.
