Denon avr 5800

Speaker cable accidentally touched. Power on but no sound. Replaced fuse several times but every single time is blown instantly as power is turned on.

    Hi I have the same receiver BUT all my lights and status indicators are on but I have no sound in any digital input modes - i plug an ipod into the CD input and I can hear Stereo, Pure Direct and Direct (it is the sweetest ounding amp i have ever heard) but nothing else works. I can pass thru to view OSD - no sound on the digital inputs - plugged DVD player in as well as a CONCAST BOX via Optical Inpiuts that were correctly configured. no sound coming out? is there a master volume muting button? i do not have the original repote as well - using Harmony remote. ideas? is this a fuse? transistors? blown amp, blown dsp? who knows.

I can help you solve this problem. However you must describe to me which fuse you have replaced. Is it the fuse on the power line or is it a fuse in the speaker line (which I highly doubt). usually this type of amplifier uses two technologies. One is transistors the second is integrated chips. This is in regard to the output stages. I assumed you speaker cables shorted each other while the volume was set at a high level with music playing. Anyway if you are willing I am able to help.

  • Tinu Patel Sep 02, 2007

    Now the problem is somewhat clear. I suspect shorted transistors or main capacitors are shorted. This requires some troubleshooting on your part. However if you need me to help you you need to be in new jersey. Or else you can send me pictures of the amp opened with the top cover off. I can the direct you on troubleshooting.

  • Tinu Patel Sep 05, 2007

    OK this is a convential power supply system. If the power does come on and stays on most likely nothing is wrong with the main capacitors which are the two small circles to the left of the big black circular transformer. It is safe to say you have blown transistors. If you are familar with testing diodes then you need to put the DMM in the diode checking mode. Next realize that a transistor BJT are usually two diodes back to back. It may be also possible you have mosfet power in which case the testing is a little different. If you are willing to do this kind of troubleshooting, judging from the picture it seem a lot of work to get to the transistors that are mounted on the heat sinks let alone trace the correct one for the front channel. Your amplifier should have protected itself from the short circuit. Did you short the speaker terminals together at high volume? or did you blow out the speakers at high volume? The reason for my asking is very simple, the short circuit protection circuitry could be at fault where it keeps the output from turning on even though everything is ok. In conclusion the only way I can really help is for me to look at it myself. Even then I cannot guarantee that we will be able to fix it.

Standby light stays on after blinking , stays power up but no sound

The issue you're experiencing with your Denon receiver AVR-1700 may be due to a few reasons. Here are some troubleshooting steps that you can try:
  1. Check the connections: Ensure that all cables are securely connected to the receiver and the speakers. Make sure that the input source is selected correctly on the receiver, and the volume is turned up.
  2. Reset the receiver: Sometimes, resetting the receiver can resolve issues with the sound. To reset the Denon AVR-1700, turn off the power, and unplug the power cord for about 10 minutes. After 10 minutes, plug the power cord back in and turn on the power.
  3. Check the speaker settings: Ensure that the speaker settings are configured correctly on the receiver. Check that the speaker wires are connected properly to the receiver and the speakers. Make sure that the speakers are not damaged or blown.
  4. Check for firmware updates: Make sure that the receiver is running the latest firmware. Visit the Denon website to check if any firmware updates are available for your model.
  5. Check for hardware issues: If none of the above steps work, there may be a hardware issue with the receiver. In this case, you may want to contact Denon customer support or take the receiver to a professional repair shop for further assistance.
Hopefully, one of these solutions will help you resolve the issue with your Denon receiver AVR-1700.

I have a Denon AVR 3310CI everything appears to work HDMI inputs recognizes speakers but zero sound ???

If you have verified that the Denon AVR 3310CI is properly configured and connected to the speakers but are still unable to hear anything, you can try the following troubleshooting procedures:
Examine the HDMI cables: Check to see that the HDMI cables are securely connected to the HDMI output port on your source device and the HDMI input ports on the receiver's back. To see if that resolves the issue, try substituting new HDMI cables.
The microprocessor must be reset: The functions of the Denon AVR 3310CI are controlled by a microprocessor. Try powering the receiver back on while simultaneously holding down the "Power" and "Speaker A" buttons to reset the microprocessor.
Check the settings for the sound: Check that the sound settings on the receiver are set up correctly. To ensure that the settings are optimized for your particular setup, check the model's manual.
Aktualize the firmware: Check to see if the Denon AVR 3310CI's firmware can be updated. For additional information on how to update the firmware, you can visit the Denon website or get in touch with their customer support.
Use a different source to test: To determine whether the issue is with the receiver or the original source device, test it with a different source device.

When I power my Denon AVR-3311ci on, it only comes on for a second then shuts off completely. No blinking red light and nothing on the display. I can hear a relay on the power board clicking. Any ideas?...

Greetings
have you checked the speaker cables ?
please do
Usually the Denon system has a problem with power regulators
if u have any knowledge in electronics i can guide u to repair it
if not .. u have to send it to service.

check for fuses if blown
power regulators mostly are damaged
and or power output transistor damaged
Good luck From Audio-adviser.com

No sound

check speaker conections. disconnect all the speaker wires and use one speaker that you know that works and connect it to each channel one at a time. most surround sound stereos will not go into surround mode unless all the speakers are connected so make sure stereo is in 2 channel mode to start testing. check all fuses sometimes amp fuse is seperate from power circuit and denon uses relays in 99% of thier units.

The left side main output won't put out any sound on my Denon AVR-900.

connect your right speaker cable to the left output, if the sound comes out then the problem is on the left speaker ( the cable or the speaker itself ), but if still no sound, then the problem is on the power output of the unit, need to repair them

I got the same problem with my Denon AVR-2105/885

Your receiver is going into protection. The first thing to do is disconnect all speakers at the receiver. Unplug the power cord, then let it set for 30 seconds. Plug it back in and power it on. If it stays on, you have either a wire shorting out at the back of the receiver, something that has pierced the speaker wire en-route to the speaker, a wire touching the other at the speaker or a blown speaker.

Speaker wires should only be trimmed about 1/2" bare at the terminal and make sure you twist the braid so it does not fray. Then connect speakers one at a time, testing the receiver power each time until it either shorts and cuts out, or, you have solved the problem. Hope this helps. If you need more help, post a comment and I can help you some more

Protection circuit momentary activation. Not heat/speaker problem

Is it possible for you to lower the source level? if yes go ahead...

There is an automatic Dialogue normalisation function in Denon which is activated to reduce overly bright input signals. ( most movies have wide variation in sound levels and therefore this function is avaialble). (see page45 of your user manual).

When your system worked fine with the AVR 2808CI, then why is it giving problem with AVR 3808CI....???? You must ask Denon.

Protection circuits are activated when:
1). There is rise of internal temperature.
2).Core wires of the speakers are touching each other or a core wire is sticking out of the terminal and touching the set's rear panel or the speaker itself has a problem.
3). Speakers with an impedance other than specified are being used.
or
4). the set is damamged or has bad solder / dry solder connection .

If your AVR is new, please do not accept, the set could be faulty. The protection circuits should not be activated unless any of the above happen.

You must know, at times the protection circuits are not fast enough and it could burn some of the transistors on the power output circuit. With time, the solders on the circuit board could give way and give you problems later on.

You must sort out with Denon if the AVR is under warranty.

Best of Luck.
