Denon AVR-3300 won't come out of Standby mode

For the second time in as many months, our Denon AVR-3300 has refused to come out of standby mode. Last time, unplugging it and replugging it in did the trick, but this time it hasn't. Pressing the Power/Standby switch does nothing, nor does using the remote.  The On/Standby light stays on, but nothing else happens.  Any suggestions?

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. :)

sounds like overload protection
turn the volume all the way down, then turn it on
if that doesn't do it you may have a short in one of the speaker lines - try disconnecting them one at a time

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.

SOURCE: Denon receiver AVR-3300: Unstable source selection

Very important you have run system set up menu it configures your receiver with inputs analog or digital,speaker size,input,room correction etc Different input modes can be selected for the different input sources.
The selected input modes for the separate input sources are stored in
the memory.
q AUTO (auto mode)
In this mode, the types of signals being input to the digital and
analog input jacks for the selected input source are detected and
the program in the AVR-3300’s surround decoder is selected
automatically upon playback. This mode can be selected for all
input sources other than PHONO, MD/TAPE and TUNER.
The presence or absence of digital signals is detected, the signals
input to the digital input jacks are identified and decoding and
playback are performed automatically in DTS, Dolby Digital or PCM
(2 channel stereo) format. If no digital signal is being input, the
analog input jacks are selected.
w PCM (exclusive PCM signal playback mode)
Decoding and playback are only performed when PCM signals are
being input.
e DTS (exclusive DTS signal playback mode)
Decoding and playback are only performed when DTS signals are
being input.
r ANALOG (exclusive analog audio signal playback mode)
The signals input to the analog input jacks are decoded and played.
t EXT. IN (external decoder input jack selection mode)
The signals being input to the external decoder input jacks are
played without passing through the surround circuitry Your remote is searching for inputs because you did not properly run system set up!!! Here is a link to your manual [PDF] AVR-3300/1 3.3E*

Denon AVR-3200 wont go into standby mode

Not sure what you mean by standby mode. The power button on most of the audio remotes I deal with merely turns the equipment on and off.

Denon AVR-1908 won't power on

Are you getting a standby light at all? Is it flashing? Do you here a click when you plug the unit in? If the answer is no to all of these then you blew a fuse. If you do have soome sort of standby light, then your set is in protect mode. More than likely for a blown channel. If no lights, but you ar egetting a click, you could have a bad transformer. Use a DVM and see if it is open or not. Good luck

My Denon AVR-75 seems to stay in standby (red standby light is on) and I don'd get surround sound through it. How do I get it out of standby?

if the receiver does not power on from standby there is a problem like bad power supply or even bad macroprocessor. You need to bring it to a service center for diagnosing. 10-years old receiver, maybe better to buy new one.

Unit''trips'' off shortly after powering up

Disconnect ALL of the speaker wires from the back.  Turn it on again, if it still trips, then the unit needs to be repaired.  If it does not trip with no speaker wires connected, turn it back off, connect 1 speaker at a time and turn it on, when it does trip, that speaker that you just put on has a short somewhere, it could the be the wire or in the speaker.

Stuck on standby

Unit is in protect mode there are a few problems that can trigger protect mode the most common is blown channel (shorted outputs). Sometimes one of the 15v regulators may go bad causing imbalance of supplys triggering protect mode. Also sometimes a bad solder connection could cause unit to go into protect also. I work for Denon authorzied repair center in Michigan if your nearby and Shipping to Michigan is economical let me know

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.
