Denon Receiver No Surround Sound Fix and Display for Red Blinking Light 

You're the man, Daniel! 👍

Great to hear you got it back, mikem!

From Mikem. The problem was not the SVS speaker but a bad banana speaker connection to the speaker. Speaker now works fine.

Thank you for visiting my channel :)

You're welcome, my friend!

Hi Jonathan, It could be a few things so I'll give you a couple ideas: 1. Super easy, make sure it isn't simply a setting that has been enabled / disabled. If one zone has appropriate volume and the other does not, that will be a clue to your problem as well... 2. Check voltages across your power board 3. Test your output transistors 4. Look for blown capacitors Denon's aren't exactly fix-it-friendly, in fact, I have one now that I've been dragging my feet to fix (probably a voltage regulator?). Hopefully, I'll post that video later this year. Good luck, my friend, and thank you for stopping by my channel 🍀

Hi Marko, remote diagnostics like this are difficult, but it sounds like an interface problem. These Denon receivers tend to lock into certain sound settings. I would start out by plugging in all the speakers (old and new) and then re-run the Audyssey Setup to see if that recognizes the new speakers. Let me know if that does the trick. The next step would probably be to restore the AVR factory settings. Good luck, my friend.

Gilson, if it is working, don't do anything except enjoy your receiver. I recently was given another to fix, same blinking red light, but I have a feeling it is the voltage regulator. Stay tuned. If it turns out, I'll post the video in the future. Thank you for checking out my channel 😎

@@VestigialVoice Thank you very much for responding to my comment! Really you are right, because my case only presented problems that day after that no more, or that it could have been the socket misplaced and because I was short on cash I was not able to buy an energy conditioner until today and maybe there was a voltage variation due to energy received or it may also have been heating because the symptom is described in the manual as heating !! I will wait for other videos that you publish on this issue !! Thanks!!

@@gilsontavares9152 It looks like you've got an Overheat protection from your Denon after a couple of hours of usage. You better of puting some fans placed over your AVR blowing that hot air from inside away. Also make sure the receiver has enogh clearance all around it.

@@tonifatec Thank you very much for the tip, I saw that it really could have been that too, in the practical manual they detail this, I will buy a fan yes to do this function! Thanks!

Hey Pete, Distance-troubleshooting is always difficult, but perhaps I can begin to point you in the right direction: 1. Did the display work up until the point the fuses blew? 2. Do the faceplate buttons still function?

@@VestigialVoice Faceplate buttons no longer work and the display worked up until it stopped working... Maybe it would help if i told you how it broke.. I was trying to blow a small speaker and the amp protect kept shutting my reciver off.. I kept turning it on over and over till it stopped working..

Heh he, I'm not going to ask WHY you did that, but it IS helpful diagnostic information. :) The good news is: You probably only blew one (or a couple electrical components). The bad news is: They could be in a variety of places and you'll have to hunt them down. First step, visually inspect for signs of scorching. If you're lucky, you'll find something (however it may not be visible). Replace those pieces. Second, if it were me, I'd hook up an external power supply to the faceplate and see if it turns on. This will help you isolate the location's site. Happy hunting, my friend 🤞😊🤞

I love the sleek look and smooth sound of denon receivers, but I'm with you, they really should swap out a few of their cheap, lynch-pin components (and replace them with quality ones) if they hope to preserve a credible name in the home audio industry.

@@VestigialVoice yeah because I own a Denon amplifier and I love there sound it’s just a shame that this has to happen mostly with Denon

Which cost are you referring to, Cynthia?

Hi Sherif, Please feel free to ask here. Perhaps, that way, we can all help teach each other :)

@@VestigialVoice Hello, Thanks for your response, I have followed your video and changed the 2 capacitors and further more the diode, but the result is the same, check the video in the link; ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zuSVhUPv_bY.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZcjgP1hi-4k.html If you have further advice

Hey Sherif, So, did the subwoofer's performance change at all after swapping out those components or is it EXACTLY the same? Hope to hear from you soon.

@@VestigialVoice at the begining there was almost no sound coming out, you can hardly hear sound, NOW sound is coming out with this buz and like a sine wave (UP and DOWN) and when i remove the cable the buz degradation start at the speaker and end by the relay on and off degradation as well

The oscillation, or "sine wave" as you describe it, points a guilty finger at the incoming power source. It may take some investigating to find out which component is the actual culprit though. I don't have a good idea of your experience on electronic work, but some common mistakes include: cold soldering, improper cleanup with isopropyl alcohol after electrolytic spillage or flux use, soldering the capacitor in reverse polarity (there should be a negative strip on the cap to match the negative on the PCB) to name a few. If, after replacing the caps and diode bridge, the performance was identical, perhaps you just replaced good parts with good parts and the actual problem lies further upstream. In that case, you'd beginning to check voltages around the transformer, but please be very careful when doing so. Good luck, Sherif. Something tells me that you have a decent shot at fixing this! I look forward to hearing about your progress. :)
