I've just upgraded my Onkyo amp to a Denon 1912. I've connected my Xbox360 to it via component (Its a launch day unit so no HDMI).
If I flick the HD switch on the output cable to off, I get a picture fine in fuzzy old 480i. However, If i flick the HD switch on, the screen goes blank, even though it worked fine on my Onkyo amp using this method.
Anyone have any idea what is causing this?
