I recently got a DISH 811 HDTV receiver. I am running it thru a Yamaha HTR-5550 with component cables to a NEC IPS-4000 image processor and then out to a BARCO DATA 701S CRT projector via RGBS cable. I am unale to get a picture. I have tested it successfully on an LCD panel, so I know the receiver and cables are working. I'm assuming it has something to do with the image processor. I'm new to HDTV, so I'd appreciate any help.
