Thanks for the reply. Turns out the reason my Prometheus 3D blu-ray displayed nothing but a black screen in the Panasonic 220 had to do with a handshake issue with my pioneer 521-K receiver. On a hunch, I connected the blu-ray player directly to the television and lo and behold the movie came right up. After putting the receiver back in the loop, simply switching away and back to "BD" as the receiver source made the receiver pass the image along to the TV.
That said though, it shouldn't be that way and unfortunately pioneer has not a single firmware update available for my receiver, meaning no possible fix available. And the 521-K owners forum here gets about one post a month, so not a huge community to offer assistance. I suppose it's worth contacting Pioneer to see what they're willing to do for me.
