So I'm playing Metal Gear in my Home Theatre, and suddenly my Receiver turns off. I turn it on again and it turns off, sooner than last time. I turn it on again, and it shuts off right when it gets an audio signal. And also, I did notice when I was playing, Pro-Logic sounded like a fucking "stadium" mode, there was absolutely no sound coming out of the center channel. Today is the first time all these events happened. So I'm thinking the safety shut-off or some sort is working? BTW, it's a Yamaha RX-V793 unit powering Energy Take 5 speakers. Thanks in advance.
