Home Theater Questions? Ask a Technician for Answers ASAP
Hi, I'm Nathan.Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.
Is the pop from the denon, or from the speakers?
Does it turn itself off, or does the display flash or the red light flash?
My apologies for the delay. The site is not quite instant, but please try to send only a single response and allow me time to receive it and respond back; multiple messages can get lost in the queue and further delayed.
Are you listening to very small speakers, or at high volumes?
Is the denon in an enclosed cabinet or shelf, or stacked with other components?
I ask because this can be from overheating, since it has been a few years it would be a good idea to blow everything (side/top vents) out with compressed air and vacuum it thoroughly.
Beyond that, this indicates a hardware fault, meaning a short in a speaker or internally in the amplifier.
You can try a few fixes yourself. To begin, with the receiver powered off, disconnect all speakers and components. Try to turn it back on in Tuner (am/fm) mode and see if it will stay on (by itself, connected to nothing but power). If it does, power off and reconnect 1 speaker, then power on to test again. Continue this process until you isolate the speaker or component causing the problem, or until everything operates normally.
Let me know the results, or lack thereof, and I’ll advise further if needed.
Yes I realize it will take awhile, as it is a process of elimination. It is also possible it will be fixed in the process if there is just a stray wire somewhere that is shorting, and reconnecting them all can resolve that.
Thanks, ***** ***** long as you need and get back in touch anytime.
Thank you for checking, unfortunately that does then confirm an internal hardware defect.
This issue could be a manufacturing defect, but is also often caused by a power event (shock/surge, prolonged over/under voltage condition, etc).
There is no quick fix for this, it would require repairs to correct the problem, but this type of repair is typically not practical. It will cost as much or more to fix as it would to buy a brand new receiver with updated features and a fresh warranty.
Depending how you’d like to proceed here, I can help with finding a repair shop, or recommending replacement options. Just let me know.
