I have a Denon AVR 1908 making popping noises intermittantly through all speakers. The procedure for resetting the microprocessor in the manual did not work after three attempts. Denon thinks it is the DSP board and is willing to authorize a warranty repair even though it is one week outside of the two year period. The three closest repair centers they gave me to pick from all have terrible customer ratings. Who does the best repairs that I can get Denon to send an authorization to, or am I better off forgetting the whole idea? I researched the likelihood of a long-lasting repair and it doesn't look good either.

Hi,

You seem have a problem with a component in that channel, the bad news is that it is hard to fix that type of problem (you would be better off if the channel died). All of the components in the final output section are part of the same audio loop (per channel), which makes it hard to find the faulty part.

Sounds to me like a bypass or coupling capacitor is faulty or need to be re-soldered, either way to fix this problem you should take it in to a repair shop.

I hope that helps and sorry for the bad news.

Check for nearby wireless devices and move them away. -If the audio output from the source device (i.e. DVD, CD player) is digital (i.e. PCM, DTS or Dolby Digital) you're on your own. I'd be willing to bet the output is analog (red and white RCA), because the "beeps" and "exploding sounds" you describe seem like it could be caused by interference. Try replacing the cables. Otherwise the issue is probably with your receiver.

Hi


Thanks for using FixYa. Store these instructions in a safe place. After reading, store these instructions along with the warranty card in a safe place. Whenever the power operation button is in the STANDBY state, the unit is still connected to AC line voltage. Please be sure to turn off the power operation button or unplug the cord when you leave home for, say, a vacation. Note that the illustrations in these instructions may differ from the actual unit for explanation purposes. Please click on this link for further reference---

I had the same issue..I called Denon support and they fixed the problem. You need to reboot the micro-processor....turn off the unit...hold down A+B then turn on...the display blinks (all the display is illuminated) Let go of the buttons.....issue resolved!

Good luck....
