It's a shame to have to buy another calibrated mike instead.

You can just turn down the center to where you can no longer hear it.

For some reason you might have encountered a glitch during your attempt at calibration and locked up the calibration.

If all your speaker cables are properly hooked up and there are no shorted wires, etc., then your AVR might need a reset.

First try a "soft" reset. Disconnect the AVR from its power source. Don't just turn it off. Unplug it or turn off whaterver it's plugged into. Wait a minute or two, then restore the power and try Audyssey again. This proccedure might do it for you.

If that doesn't do the trick you should try a full ("hard") reset. I'm not familiar with the exact proceedure to use on your particular model, but you can find out through Onkyo product support (800-229-1687).
As an example, with my AVR you would:
1) Turn the receiver on.
2) Press and hold the VCR/DVR button on the front panel of the receiver (not the remote) and while holding that button down press the STANDBY/ON button on the front panel.
3) The word "Clear" will come up in the display screen and the receiver will then go into the standby mode. All of your custom settings will be lost, it will revert to the factory default settings as if it just came out of the box.
4) Once it goes into the standby mode you can turn it back on and proceed to go through all of your stettings in the setup menu, including the Audyssey calibration.

Time consuming, but far better than having to box it up and return it to a factory service center. It's worth a try if all else fails.

Cheers,
SB

Actually you can take out a speaker that Audyssey has pinged and corrected without re running, at least on the Denons. Did it all the time, running DynEQ almost always, so I know Audyssey did not go away.

To the OP, assuming your receiver works like my Denon, since Audyssey pings the speakers indepently, there's no reason to rerun Audyssey. The center that is not making any noise has the same noneffect on the left right and surrounds whether it's not making any noise because Audyssey is not pinging it or because it does not exist.

thanks in advance

I don't think you can switch from a hard center channel to a phantom center channel without changing the speaker configuration in settings. And I think when you change the speaker configuration Audyssey is turned off with the only way to get it back being to re-run it. I have never tried it, so I am only speculating. Maybe it is smart enough to know that the whole system doesn't need to be re-done, but then maybe not.

I'm sure Audyssey knows or has a record of exactly what the frequency curve is on each mic. So, Please don't tell me nothing like that exists or is irrelevant. It may or may not be relevant to what several of us are experiencing. But this information would be nice to know, without my having to go down and buy a frequin meter.

I think this is a question that matters; My old AVR sounds nothing like my new AVR, when setup with their corresponding mics. The new AVR sounds better using the old mic. (JOEROD has found the same to be true on his system.) I think this difference goes beyond reference vs. preference. This has left me to think there may have been a bad batch of microphones. Others are also saying their AVR's don't sound right to them.

My final verdict! I am considering this case closed. Thankfully the other newer mics produced different results then the first newer mic. Hope that makes sense. Who knows, maybe this mic was dropped or simply a bad one? Either way I am done hearing those crazy noises for awhile. I can't get them out of my head!!!

It uses MultEQ (!) configured for anechoic mic calibration to allow the assembly line workers to quickly test each mic as it comes off the line. Mics outside the frequency response tolerance are thrown out and never shipped. That tolerance is ±2 dB from the "golden mic" response. Mic manufacturers tells us that the typical mics that ship with receivers are usually in the ±4+ range so we feel pretty good about our process.
