Question about Denon AVR-1705 Receiver
I've been using the Denon AVR-1705 for 2 years now, and the audio out to the speakers no longer works, I've tried it on multiple inputs. There isn't even a faint hiss. However I can get audio out from the headphone jack on the front. Does anyone know how to fix this?

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. :)

If no sound coming through Zone 2, steps that worked are below. Layout: Denon AVR-988 running in 5.1 mode with patio speakers designated as Zone 2: 1) check that patio speaker wires are connected to Denon's back surround speaker terminals, 2) check "Menu then "Manual Setup" and scroll to check that "Amp Assign function is set to "Zone 2". You won't get Zone 2 sound unless this is chosen in this instance. Also check the volume settings in the "Manual Setup" to ensure you haven't turned sound down by -40 DB or limited it. Now try turing on Zone 2 sound either on front panel or on rear of remote. If you still have no sound, what worked for me is there's a Zone 2/Rec Out pushbutton on front left top panel by round input knob. This must be set to "Zone 2 Source" and not "Rec Out Source".to avoid diverting the signal to the Rec Out jacks. Keep turning the input select button until it reads "Zone 2 Source". Then turn on and this should route the signal to your Zone 2 speakers. srhfish

On the Denon AVR-888 (and I presume others), you have to put the unit in "record" mode. This is covered under "Other Operations and Functions" in the manual. Here are the steps:
1. On the front of the unit, press the zone2/rec select button
2. Turn source select until "recout source" is displayed
3. Turn source select to choose the input source
Hope this helps.
