Needs to be reset or fuse blown. Take to repair shop, cover has to be taken off and fuse replaced. You could fix it yourself but the warranty won't be honored. Do it yourself electronic shop should have a replacement fuse, may have to be soldered in place. Repair shop, should cost around $30.00 to $45.00 to fix, price of fuse $4.00 to $6.00. Your choice.

You're drawing too much power from it. Sounds like maybe your sub is hooked up wrong, double check that.

If your amp looks like it's going to work as normal (ie the front display lights up as it should etc), but then the amp goes into protection mode when the anti-thud circuit times out, then I know what's likely to be wrong.

It's one of the power amplifier channels which has gone faulty.

I just found this out after having this problem with my AVR-1906.

I took the amp apart and de-soldered the suspected channel power transistors (centre channel in my case).....and hey-presto! it fired up as normal (obviously the centre channel would be out of service).

I have ordered the replacement transistors from Farnell (UK) at a miserly cost of around £2-£3 each.

Just waiting for them to arrive.

An alternative is, if you don't use all your channels, take the transistors from a known working but not needed channel and swap them over with the duff ones.

Hope thats of use!

Without looking at the schematics for this particular model, I'd surmise that the click is indeed a speaker protection relay. Generally this is fed by a number of different sense circuits that watch for power amp issues and/or excess speaker current and/or power supply output stability. Although the relays do indeed fail at times, generally it is not the relay that is at fault. If you have a scope and a schematic, you can check the various circuits that feed the relay for the exact cause. If not, you can do some experiments that might help deduce the problem: e.g. do headphones work when speakers do not, does the relay click on when no speakers are connected (or selected), etc. In my experience, it is most often the output transistor(s) in the power amp. But not always ;-)

Try unplugging the entire unit and letting it sit for 5 minutes. See if this helps. If not, you need to do a complete reboot, which will cause you to lose your settings, but will probably solve your problem. To do a complete reboot, you will need to hold down two of the front bottons on the front panel. I'm not sure which, so either consult your manual or see other posts here which describe the reboot process for Denons. Hope this helps.

SOURCE: denon receiver (DRA 397) will not speak to iPod dock

IF YOUR NOT USING A DENON IPOD DOCKING STATION IT WILL NOT FUNCTION CORRECTLY.
YOU CAN CONNCET OTHER TYPES OF IPOD DOCKING STATIONS BUT YOU WILL NOT HAVE CONTROL THROUGH THE DENON AND ONLY CONNECT THE AUDIO FOR THAT DOCKING STATION TO THE DENON AS ANOTHER SOURCE INPUT

Protection


I just had this same problem and called Denon. I was told to unplug the unit and unplug all attached to it. Then, push both the tuning buttons at the same time (both the up and the down) hold them in while plugging the Denon back to the electrical. Watch the front of the Denon and see 5 cycles flash on the tuner display and then let go of the tuner buttons. Then plug things back in.
That helped the protect thing for minutes. I redid it several times.
No good. One of the channels blew out. I would now get rid of it for parts. I have not had luck with Denon.

If you are not pressing the power button on the remote that may be the problem

The power supply has burnt out on my denon dra-455 reciver.


It really depends what and how much burn't up? The only way to find out it to take the top cover off and look inside. A lot of parts in the power supply section can only be replaced by excat parts due to safety reasons. And are you certain it's the power supply that's gone up, and not the POWER AMP section? It could be just one part that started smoking. If any semi-conductor has burnt up, you might not be able to read the code number, in which case you will need the service manual.
SO GET LOOKING INSIDE!

Denon DRA-37 Receiver-Remote lock on. Need to unlock.


Refer to the "Initialization of the Microprocessor" section of the manual (page 16 of the PDF version of the manual).
1) Turn the unit OFF using the On/Off switch (not the standby switch).
2) Depress both the Speaker A and B switches, and turn the Power ON.
3) The entire display should flash at 1-second intervals. The microprocessor should be reset, and the remote should be unlocked.

Denon DRA397 Panel lock on.


Hello,

Denon has for some reason removed this function from their user manuals. However The manual does show how to do a manual reset of the unit. This may correct the issue.

With the Amp OFF but plugged in, press and hold the speaker A and B buttons and while still holding them press the POWER button. Continue to hold the speaker buttons for another second or so. The display should all light up and flash at 1-second intervals. If not flashing, try again.

This should reset the unit back to factory state with the front panel lock disabled.

This worked for me, but I'm sure tired of constantly searching for ways to fix the problems I encounter with my Denon DRA-397. When it works, it's great, but I don't have a degree in electrical engineering. Why can't they produce a user friendly trouble shooting guide?
