I have an issue with my A8A. I turned on my Apple tv 4K hooked by HDMI cable into the AVR and I got a black screen. I turned on the Shield to the same black screen. I turned on the Apple TV 4K 2021 same black screen. Three different players, hooked to HDM! 1, 2 and 3, same error? I did a factory reset of the AVR. No improvement. Not only the screen was black but the AVR was not showing any setup or options screen. Turned off the AVR, unplugged it from the mains, I changed the Shield from HDMI 1 to HDMI 5. I got a picture. Unplug, mains, moved to HDMI 1, black screen. I changed the Apple TV from HDMI 2 to HDMI 5. No picture. Moved it back, no picture. Changed the HDMI Video format to Mode 2, no picture. Changed the HDCP from Auto to 1.4. I got picture. On all devices. But not on Auto. Anybody having this behavior on their AVR A4A, A6A or A8A?
Thank you for your help.
