Just installed a Yamaha RX-V630 receiver with an existing set of of SONY home theatre speakers and if I go to -41db the receiver powers off automatically. My speakers are rated at 8 ohms and are rated for 100 watts. I have checked the impedance as suggested by the owner's manual and I have also checked the speaker wire connections which it suggests. Any ideas why this may be happening? I do have some fairly thin speaker wire for the center speaker and the left front speaker - could that be the problem?
Thanks.

What happens if you disconnect the speakers and turn the volume? Sounds like a bad unit to me.
I've seen this several times. Check your speaker wires carefully to make sure one of them is not "shorting" (even one small strand touching another of the opposite polarity will do it ( + /-) ). Also make sure they're all connected solidly. Once you've made sure of that, your problem should go away, even with the thin wires.
I'd also suggest you go to Home Depot or similar store and get some 2-conductor cable (lamp cord) 12 gauge and use it. It's very inexpensive and will do the job.
It's possible you have a "break" in one of the wires too, but you can test that by plugging in one channel at a time.

Removed all speaker wires and turned power way up and it did not power off. Reconnected all speakers replacing wire on center speaker and right front speaker with 16 gauge speaker wire. It seems to have fixed the problem.
Glad to hear your problem is solved. At some point in the future, you should likely replace all your speaker wire with at least 14 ga, preferably 12 ga. You can purchase 100' for about $25 at Home Depot/etc.
When you cut it, leave about 6" extra (or more) at each end. This will allow you to remove 1/2" or so each year or two to always have a "clean" connection.

57U. Looks like you were right again, speaker wires must have been shorting out. Sometimes disconnecting them is the only way to find/fix the short since some cabinets have limited access once everything is inside.:D
Cheers,
