Just bought a new STR-DH520 receiver. Whenever I turn volume up, it goes into protection mood & shuts down. I returned it thinking it was a malfuction but the second one is doing the same thing. Now I'm not sure if there is something else wrong besides the receiver? Got any advice? Thanks.

Check to make sure the speaker wiring at the back of the AVR as well as at each speaker does not have any loose strands from one post touching a nearby post. If you have any in-wall wiring, it's possible the cable may have been split by a nail or other sharp object. It could also be a defective speaker. If the speaker wiring checks out okay, then disconnect all speakers and add one back at a time to see if adding a specific one shuts down the AVR.

That is a 7.1 receiver...are you using a 5.1 setup by any chance?

With my Yamaha when I first got it, I put the rear speakers in the surround back ports on the back of the receiver. Every time I turned the volume up, it would go into protection mode and shut down. Called Yamaha and for 5.1 setup on a 7.1 or 7.2 receiver (at least the Yamaha anyway), the rear speakers should be connected to the surround ports on the back of the receiver, not the surround back ports.

I have a 5.1 setup & I originally put the back speakers on the back ports. After talking to Sony, they told me to put the back speakers in the surround ports but it still hasn't fixed the problem with it going into protection mode if the volume goes to loud. Thanks for the advice.

Finally solved the problem! A specialist at Sony told me to unplug the receiver from my power surge & plug it directly into the wall. I guess it was drawing to many amps (at a higher volume) than my surge can handle. Such a simple/logical fix - I don't know why I didn't think of it. Thanks for your advice on the matter.
