Welcome to the shack Bob!
I am so sorry to read about your projector HDMI issue. You know that you should first turn it on and then the PS3, otherwise there might be some handshake issues. Re-Check the HDMI output
IS enabled on the PS3. Re-do the PS3 setup and check again for one last time. Let the receiver out of the loop for now.
If you still have issues, your unit might need servicing...
Let us know what you find after making sure PS3 is putting out through HDMI.... And don't pull your hair out, it may be only a small issue that could be easily solved or repaired
