Contour2 and projection tv issues

I had Contour2 set up today.  I have several televisions, and the boxes work on all except my JVC projection tv that runs through a Yamaha AV Receiver.  The scree will show that it is setting it up, but then shows no input and I have a blank screen.  I hooked it directly to the projector and it worked fine.

Does anyone know any settings that need to be changed?  I have the same AV Receiver in another room with a 65" Sony and the cable box is working fine.
