First check for fuses. Not knowing the brand, model nor any other clues makes your post really too general to give a more specific solution. Good luck, Steve Medley

No sound and light on input selector knob is Flashing. Light only flashes when speaker switch has been turned to A, B or A&B.


This can happen if there's a dead short in a speaker wire or if you're using very low impedance loudspeakers at high volume for an extended length of time. If the protection light came on due to a speaker wire short, low impedance condition or a bad speaker, the receiver's power will need to be turned off to reset it. Before turning the power back on, all speaker wire connections should be checked for their integrity at the receiver side and at the speaker side. If the protection light goes on immediately after you turn on the receiver, disconnect the speaker wires at the receiver side and retest. If the receiver's protection light goes off, then there would still seem to be a problem with one channel's speaker wires or speakers. Connecting them one by one and retesting should allow you to find the problem speaker or connection.

As soon as the speakers are turned on, there is a popping noise through the speakers then the receiver shuts off and stand bye light blinks


Sounds as if you may have a bad speaker component that is causing the unit to go into a protection mode to protect the unit from shorted speakers/outputs. Try to unplug the speakers entirely and then turn on the unit...If it still does this and goes into standby with the speakers disconnected then there is a problem probably in the audio amplifier circuit that will need servicing by a technician. If the unit stays on..then I would try to put different speakers on the unit to see if it works..if so, then suspect your speakers...if not , then suspect the receiver

It keeps blinking protetor


The protector circuit protects your amplifier from shorted speakers . One of your speakers , or more speakers are shorted out . To figure it out easily follow these instructions . Turn the unit off . Now unplug all of the speaker wire connections from the back of the unit . Turn the unit on . Make sure the volume is turned all the way down . The protector light should not light up . If it does , the problem is inside the unit itself and we'll have to be repaired at the shop . If the protector light is off than continue on as follows . Connect the speakers one at a time to the unit . Each time you connect a speaker , turn the volume control up and back down making sure the protector light does not come on . When you connect the bad speaker , the protection light should come on . Whichever speaker makes the lights come on when connected is the bad speaker and should be replaced .

Stopped working


Speakers wire conductors should not touch anything but the points on the amp and one speaker terminal each. Look again.

Will not turn on

There may be a short circuit in the speaker terminals.



Disconnect all speakers and try it. If it works troubleshoot each speaker one at a time. Shorted wires are indicated.
© Disconnect the AC cord, then correct the speaker connections.

When I switch on my Kenwood A-722L all the lights start flashing and 'PROTECT' appears on the display. Any ideas?


You have an amp failure, this can be a problem with a speaker but is more often a shorted output channel.

You can check to see if it is a speaker by disconnecting the speakers and then turn it on. If it goes into protect again, you have a shorted output channel. If it turns on, you may have a bad speaker.

If it turns on, try connecting one speaker at a time until it goes back into protect. When it goes into protect, you just found your bad speaker (last one connected).

Make sure you turn it off before connecting a speaker. Then turn it back on again. Do this for every speaker you have.

If it stays in protect, you should take it in for service. Unless you have the proper tools and experience working on electronics there is nothing you can do to repair this yourself. I have seen many people try who were not qualified to work on electronics, and more often than not, they cause more damage than they started with which results in a more costly repair.

Let me know if you need any more help.

Denon AVR-3802


I have repaired many of these Denon receivers over the last few years.

Since the headphones work, that means if you dis-connect the speakers it will turn on and not go into protect (when power cuts off a few seconds after turning the unit on).

The most likely problem is a bad speaker. to find out which speaker is causing the problem, do this.

Start out with just one speaker connected and then turn on the unit. If it turns on and plays music, you know that speaker is good.
Now turn the unit off again and add another speaker and keep the first speaker connected. Once again, if the unit plays, that speaker is also good.

Keep doing this same procedure one speaker at a time. As soon as you connect a speaker and then try to turn on the unit and it goes into protect, the speaker you just connected is bad.

To confirm that this speaker is the bad speaker, dis-connect all speakers and only plug the suspected bad speaker into a speaker jack that worked with one of the other speakers.
If the unit still goes into protect you know then that you have found the bad speaker.

If the unit still goes into protect, that speaker is bad and you will need to take it in for repair or replace it.
make sure you use 8 ohm speakers. if i remember correctly these Denons can use 6 ohm speakers, but those are harder to find and most home speakers are 8 ohms.

If the unit does not go into protect and that suspected bad speaker plays in one of the other speaker jacks, what you really have is a bad channel in the amplifier, the channel that the suspected bad speaker was previously connected to.

If you find out you have a bad channel, you will need to take it in to an repair center. Preferably an authorized Denon service center. There are not very many of those around. I work at the only authorized Denon service center in the entire state of Michigan.

If I can be of more assistance, don't hesitate to ask. And a good rating is always appreciated. :)

Hi Tamatar

The LED(green light) will have dry jointed on the board it mounts(solders) to. You could pull them apart and resolder the broken connection, not to big a job if you have a soldering iron and tools. They don't make em the way they used to!!

No Sound


when the amp is turned on does the unit make a clicking sound a few seconds after the display lights up.

if not the amp's is not happy with it's power or could have a speaker short. Check the display for a fault warning.

Otherwise check you speaker connections.
confirm that and A and B main speaker buttons are correct.

Try some headphones, if you get sound out of the headphone things might not be too bad, if nothing is output remove all your cables and try again.

Yes I know that can be nasty, so label all the cables first.
