My receiver started doing some crazy things lately. Whenever I have an HDMI device in any of the ports, the audio signal drops, comes back and then sometimes switches to Headphones. There seems to be a gremlin messing with the circuits??? I will be contacting Anthem on Monday...

I’m having similar issues and my MRX520 also randomly freezes (forcing me to unplug it to reset it). Did you get any solutions?

I sent it in to get serviced under warranty. Apparently it was a bad solder joint...not sure where? Then not much later I had a right surround channel go bad. Sent it in again but instead of fixing it, they replaced the preamp board without validating the channel was fixed. So after it was returned I had to send it in AGAIN but at least I didn't have to pay for shipping. This time they replaced pretty much every component but the power supply and now it all works great.
