" "I have seen a manual I which it said that dc issue, do anyone know how to disable the power on fault checking" You cannot do this. Protection can only be kicked out when no dc is coming out from speaker terminals. This holds no mater whether differential and voltage amp are defected (leakage) or protect detection SMD transistor(s) is/are leaked. They act as a switch. Download X2100W service manual and enter debug mode to check if DC or ASO(over-current protect ) makes protect.

Hi, If all else fails, try do a hard reset. You can verify from your manual, but in some units, this is merely unplugging the unit from mains for a couple of hours. Try again, if it still shows error codes (blinking lights) you probably have to seek the services of a qualified professional. Hope this be of some help/idea. Good luck and kind regards.

SOURCE: Disabling Bios Writing Protection

Sometimes the BIOS calls this protection some sort of "virus protection" as past viruses, like the CIH virus would tend to overwrite motherboard BIOS' with jargon, bricking the motherboard. Try disabling any onboard "virus" protection and try flashing your BIOS again.

Hi David

I think you should replace the lamp.

SOURCE: 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.

I have a old denon avr-1804. try to switch on power but can not. just appear a main power red light flashed rapidlly. please tell me why?


Greetings
the red flashing LED is that the Device is in protection mode.
the internal power supply . +15 volts and -15 volts are defected you need to be replace it ... Regulators 7915 and 7815 .... these you should change , might also need to check capacitors .
these are common defects for Denon . AVR units.
Good Luck
Hope this helps

I have a Denon AVR1603, recently I plugged computer in AUX connections at rear (not loud) and it kept tripping out. Eventually it tripped and now the the on/standby light fashes but nothing else happens....


The LED flash indicates that unit goes into protection. Check the power transistors, the 0.22 ohm or 0.47 resistors in the output of the transistors.

Denon avr-1506 will turn on then flash red and turn off... how do i make it stop or fix it??


In most AV receivers if the standby light flashes after turning on and you don't hear the regular click of the relay engaging after 4 seconds, indicates an output short or amplifier failure. The protection circuit prevents any further damage by not turning on system.
You will need professional help to fix this problem because even to a electronic enthusiast the construction of a typical AVR is not service friendly.

My phoenix gold x200.4 amp turns on but the protect light keep on flashing


  • What does it mean when the LEDs flash on my amplifier?
    With most recently produced Phoenix Gold amplifiers, a flashing/blinking LED is an indication that the unit is in protect mode, usually due to an overcurrent condition caused by an internal short, external short (speakers), or low impedance. Overheating will also cause the amplifier to shut down temporarily.

    If amplifier remains in protect mode, power down the amplifier, disconnect the speakers, and power up again. If LEDs continue to flash, there is probably an internal problem with the amplifier that will require service attention to fix.

    Unit keeps shutting off


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

    Power On + red LED turns on + but final relay (click) don't come so no sound


    Your audio output transistors are shorted and your unit is staying in "protect " mode to protect your speakers from 40 to 60 volts that is being sent at them from the shorted outputs. If you can use a meter you won't need the schematic MOST likely because the outputs are USUALLY the only parts that short out. The output transistors( or chip ) are mounted to the large, finned heatsink. The #'s on the transistors start with "2SA-" and "2SC-" followed by numbers. There are two output transistors per channel. If your unit uses an IC for audio output then the # on the IC will be "STK-" followed by numbers. These parts are available from tritronicsinc.com. Good Luck!

    My denon avr-1906 amp will not turn on correctly. When the standby button is pressed the indication surrounding the button flashes green but when you hear the relay click in for presumably the power amp,...


    The amp is shutting down to prevent further damage. This is what is sometimes referred to as protect mode. There is a problem with the final stage of the amplifier. The most common parts that fail are the output transistors. Figure on $15-$40 in parts plus the local labor rate for the total repair cost.

    Standby light on and system not working


    OK either a channel has blown or it has the Denon Curse. At the factory, denon installed some surge protecting resistors in the power supply. They are a little too small and well after warranty expires, one day, while playing music, or just turning it on, the resistors open up and the unit stays in protection mode. Denons were FAMOUS (or infanous) for this problem. I have repaired DOZENS of them. Take it to a denon repair shop as I GUARANTEE they have seen this before. Don't try ro repair this yourself as to get at the 4 resistors you have to disassemble the ENTIRE unit. Good luck....Rob

    Going into protect due to either blown channel or probably a 15v regulator might be down which I have seen many times also. causing unit to go into protect.
