System works fine when the input device is cable box or Apple TV. When it’s any blu Ray device, however, I get a blank tv screen saying turn power on or check connection. I tried new blu Ray, new cables, different HDMI ports, made sure correct settings, still nothing. Very frustrating. If I move the cable box or Apple TV to the port that didn’t connect the blu Ray, then it works. Either the receiver or tv is not recognizing the blu Ray. I even rebooted the receiver. Any ideas?
