Power button on remote not working

The on and off buttons on my controller have stopped working. Other buttons work (volume, DVD, TV, etc.), so I know nothing is obstructing the path, and the red light on top of the controller lights up when I press the on or off buttons. Any suggestions?

I mwas gonna suggest that you need the speakers attached but you stated later that it did the same thing with the speakers attached. The unit switching off after it checks its self is NOT a normal thing. TAKE IT BACK BEFORE ITS TOO LATE!! GOOD lUCK

Time for a little repair here. It seems that one or more channels have developed an excessive drain on the supply, and has caused the threshold to trip and shut you down. It's more than likely shop time at this point....accordianman

SOURCE: Denon AVR-1907 blinking red power button

It sounds like you have a bad speaker on the zone 2, or you have the speakers connected improperly.

When you engage the zone 2 a relay clicks and the speakers then become part of the amplifiers circuit.

If the problem was in the amplifier, it would go into protect mode without even having speakers connected to it.

If the speakers all check good, you most likely have the wrong type of speakers, meaning the impeadance is too low, or you have too many speakers connected to it.

On the back of the Denon, you will see right around the speaker output jacks, what ratings the speakers should be. If I remember correctly, it says 6 ohms or more when using only "A" or "B", and it says 12ohms or more for "A" + "B".

If you have two 8 ohm speakers on the same speaker jack you now have a 4 ohm load. That is below the ratings and can cause the amp to shut down (go into protect). Since your amp shuts down right away, I think you have a bad speaker or way too many speakers connected.

I have seen many times when people will connect 2 or 4 speakers to the one of the outputs that are designed for only 1 speakers.

If you are using too many speakers you will need a speaker distribution box. It has a resistor network built into it so the amp never sees a lower impeadance than what it is designed for.
You can connect 4, 6 or 8 speakers to one set of outputs designed for 2 speakers. You do loose a lot of power to the speakers, but it is better than blowing up your amplifier.

If I can be of any further help, let me know.

SOURCE: power wont stay on

Hope your under warranty mate and if so hope its not in Australia as they cannot fix this problem. My denon was allegedly fixed twice but has now failed a third time (just out of warranty) and denon have turned their back on me.

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!

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.

My remote is fine, but i don't know which button to push or sequence once I've changed batteries to for it to work the receiver. Each time I change the batteries it doesn't interact with the receiver, but...

Hi there,

It's likely that you've pressed one of the input mode buttons accidentally while changing the batteries. You've probably switched the remote for operation of a TV or DVD player or some other device.

To correct this problem, simply press the RECEIVER (TAPE/AMP) button once, then try the remote again. Pressing this button informs the remote that you wish to operate the receiver with it again. The RECEIVER button is about halfway down the left-hand side, above the TV button and below MACRO 1.

Please try this first. If the receiver still does not respond, switch the receiver off and back on again. It may have lost the communication with the remote. Resetting the receiver will usually correct this problem.

Hope this helps. Please let me know if you need further assistance.

Cannot program dvd player. unit does not fully answer commands from remote.


To program the DVD player's remote control to operate your TV, follow these steps:
  1. Turn on the TV, and then aim the DVD player’s remote control at the TV.
  2. Press and hold the [TV Power] button on the DVD player's remote control.
  3. While holding the [TV Power] button, use the number buttons on the remote to enter the two digit code assigned to your brand of TV.
Note 1: If your DVD player's remote control can be programmed to operate a TV, the TV brand codes will be listed in your owner's manual. If you don't have your owner's manual available, click here to go to the download center and download a copy.
Note 2: Many TV brands have more than one code. If the first code does not work, try the next available code.
  1. If the TV turns off, the code worked correctly and your remote control is now programmed. If the TV stays on, repeat steps 1 through 3 with a different code listed for your brand of TV.
Note: If none of the codes listed allows your DVD player's remote to control your TV, then the remote is not compatible with your specific model.

Let us know if you want something more else please accept the suggestion.

Verizon fios remote codes for samsung receiver

I have the Samsung Sound Bar WS1R model. I tried all of the Samsung codes; TV, audio receiver, and audio amplifier. The DVD code 3918 worked for my Verizon FiOS remote. Program it to your AUX button and it will control the volume while your other buttons; channel, menu, etc work the set top box. I hope it works for you too!

Kenwood remote 0809 wont adjust volume or change inputs

I looked thru the manual and the only two or three things I would ask would be: Is it in the right control mode? Amp/TV/DVD etc. silly I know but have to ask. Ithere a light or display that lights up when you push a button? if so, is it staying on? if so you could have a button thats jammed, it happens. Lastly it could be a microprocessor error in the remote and the remote needs to be reset. I didn't get to the process of how to do it but it is in the manual. That would be the last thing to try since programming alot of devices can be very time consuming! Lastly, the strange icon you see; is it on the lcd display of the remote or on the receiver? Hope this helps, if not send a reply and I'll dig some more for you

Onkyo htr 330 universal remote codes

I have the HT-R570 Receiver and here's what I ended up doing to use the Verizon FIOS DVR remote to turn the receiver on and off with volume control. Know that Onkyo uses 2 codes 1 for on and 1 for off so use the AUX for ON with Volume control and the DVD for OFF. (I rarely use my DVD and when I do I use the DVD remote that came with the DVD)

Use the AUX and codes 1347 or 1558 to turn the receiver on with volume control. Press AUX and OK together and release. Enter the code. it should now turn the receiver ON with volume control.

To use the DVD button to turn the Receiver OFF, you have to use the search method to capture the code. Tried every code I could find on the internet and their is no universal code for OFF and ON.) With the receiver ON, push down DVD and OK together and release (should get 2 flashes of all component keys) enter 922 and with remote pointing at the receiver press the >" (forward/pause button) then press and release the >> (fast forward button) until the receiver turns off. If you go too fast and go past it, quickly turn receiver back on (within 20 seconds) and press-release the <<(backwards button) slowly until it turns off again. Then press the OK button to store the OFF code in the DVD function button. Any questions...E-Mail me at Lots of Luck!

Blinking light on volume control

i have a same problem, but on a rx-v1070, worked fine for a long time and one day i just turned it on and boom light blinking and no sound, if i crank the volume to about 80-90% i get distorted sound, i think our amps are gone, checked the fuses and they seem ok. Most likely its the amp. This unit was around $1200 back in a day. And it still produces sounds better then many recievers in stores today, too bad it has no 5.1ch surround.anybody have a solution pls let me know, for now i have a weak pioneer with 5.1 but no power.

Code for Verizon FIOS remote Control

I have a solution which has worked well for me. It uses the DVD button at the top of the remote. It was a trade-off as none of the codes in the RC144 Philips remote will work any Blu-ray players, so the DVD button was unassigned. The 922, 955 and 977 codes are explained in the directions for the FIOS remote.
1. Set up your TV button to work your TV.
2. Set up your Onkyo code, pick one to turn on the receiver. I used 3719
3. Use the 9-2-2 code to cycle through all available codes. At about a count of 300 I found one which will turn the Onkyo receiver off. Make sure you start this process with the ONKYO receiver already on. Once you find it press the OK button.
4. Use the 9-7-7 code to power all devices TV, AUX and DVD from the power button.
In this way, each time the power button is pressed it will send both the power on and power off signal to the ONKYO receiver.
This technique works well when you point the remote at the ONKYO receiver and press power button. Apparently the TV has better reception for the signal then the ONKYO does.
