I also have a Marantz 7005, but I've never had any problems with my 360.
Do you have a 360 or Xbox One?
It sounds like you've already tried a different HDMI cable and input. Since it works going directly to the projector, it seems the HDMI out of the Xbox is working.
Have you tried changing any of the video output and processing options of the 7005? You may want to try the different scaling and output settings to see if you can get it to work.
