Have you tried this with the amazon streaming stick being removed from the AVR? I have experienced issues with the POS knocking out HDMI on Marantz and Sony AVRs. Sounds similar to the issues I was having. Remove the stick and all was well.
Not sure why, but I refuse to install amazon streaming devices because of it.
