Reliable Denon repair facility? (1 Viewer)

[Sal Conigliaro]

Can anyone recommend a reliable (ie, competent) repair facility for Denon receivers?

I've got a 4802 that makes a scratching-type noise in the background of any sound output. It only does this for digital inputs. If I switch to analog inputs, it goes away (so it's something wrong with whatever is decoding the digital signals (coax or optical)). It's not my speakers or cables (a different receiver doesn't exhibit this problem). And it's not one of those "listen closely and you'll hear it faintly". You'd have to be deaf to not hear it. It almost sounds like the speaker is blown.

I sent it to a local 'authorized' repair facility. They kept it for 4 weeks and returned it with a "No problem found". I then emailed one of Denon's 'SuperService Centers' to see if they had some sort of audio signal generator & analyzer to diagnose this. The guy replied 'no, we use a CD player and a known disc to track down the faulty part'. Doesn't exactly leave me with a warm fuzzy feeling about getting it fixed.

If anyone has someone they'd recommend, I would be most grateful!

Thanks,
Sal

Sal: I don't have any recommendations on servicing, and I'm sure you've already tried it, but I do have a dumb question. Did you try resetting the processor?

 

[Sal Conigliaro]

Oh yes. Multiple times.

It's weird in that it almost makes the speakers sound like they're blown.

Any chance you could have a friend try it in their setup and see if they get the same results?

 

[Sal Conigliaro]

Yeah, I tried that already. I hooked up different speakers (using different cables) with a different DVD Player and optical cable. Still hear the noise.
