I have a client with an old Denon AVR5700 receiver and it is doing the craziest thing...

The right rear channel... after the unit has been off for a while... sounds like someone talking into a tin can. If you take the speaker off the wall and disconnect it... then connect it again a half an hour later it sounds fine. Once it sounds fine it will play perfectly until the next day when its first turned on. If you don't disconnect the speaker it will play like crap all night.

We've switched rear speakers and the sound appears in either speaker connected to the right rear while it does not appear in either speakers connected to the left rear. We ran a new 12/2 across the floor and left it connected (our crawlspace inspection revealed no rodent or other damage and there are no shorts in the wires).

Ever heard of a rear channel that needs to "warm up" with no load connected to it?

odd problem for sure but you seem to have completely eliminated any possibility except the receiver itself.

Seems so... but can't you see the "No Problem Found" tag just waiting at the end of this one?

Kind of wondered if any of you had experienced the same thing and what the outcome was. Probably going to sedn it in as he turned me down on my Integra DTR10.5 upgrade/replacement offer.

And???? What was the result?


Ted's right.

Troubleshooting is a process of elimination. You've already eliminated the speaker itself, so now you know it's upstream of the wire-to-speaker connection.

Now, you need to know whether it's upstream or downstream of the next place the signal is accessible: the receiver-wire connection.

Try swapping the let and right rear speaker wires at the receiver's terminals and see if the problem stays in the same corner.

If this is the case, I bet you find a poor splice in the wire somewhere. If not, and it moves to the left, it's the receiver, as metioned above.

Larry, Sorry... I did all of the above... I did isolate it to the receiver (it happens on all sources so its not there... maybe I'm just looking for what the heck would cause this and if any tohers had this experience with a receiver.

I had that problem with my old Integra 6.2 in my garage.

The fix....re-soldered some circuit board connections!

Been working fine every since!

It always took about 10 minutes to 'warm up' .

If it was just powered up, it sounded like everything was out of phase.(if it had audio at all!)

Have you tried swapping the wiring for the left surround for the right?
