i have the rx-v1800 and i can tell you that if you have the hdmi resolution set to an incompatible mode with your display then you end up with a black screen. my display only supports 1080i, when i set hdmi to 1080p at the reciever i got the black screen. make sure hdmi out is connected to your tv, then press the "set menu" button on you remote. select manual setup, then option 5. goto "video set", make sure video conversion is set to on and then scroll downt to hdmi, here you get a choice of resolutions. choose the one that applies to your display. go back to manual setup and choose option 3, then option f " hdmi set" in this option ensure it displays "support audio - rx-v1800". i have my blu-ray connected to the rx-v1800, from there to my plasma screen and this is thge setup i use. works for me, hope it helps you out.
