Reconnecting Sony STR-DG820 to Epson Powerlite 8350


Oct 6, 2016
I am trying to reconnect my Sony STR-DG820 receiver to my Epson Powerlite 8350 projector (It worked perfectly in the past until I stupidly unhooked everything). I can get audio from our DVR and PS3 through the receiver to our sound system, but cannot get video from those components through the receiver to the projector (get a "No Signal" message on projector). When I connect both the DVR and PS3 directly to the projector, they both work, so it doesn't seem to be a cord/cable/connector issue. All components are connected via YPaPr at both ends. Right now I have a work-around and have the DVR connected directly to the projector for video and the DVR connected through the receiver to the sound system for audio, but ideally I'd like everything to go back through the receiver. Is there a setting I'm missing on one of the devices? Any help is greatly appreciated.
