1) Make sure the input is HDMI (assuming your player is)
2) Plug the player directly into the projector.
3) Try the other HDMI port
4) Try composite if those don't work. If that works the HDMI chip may be gone. Not the most uncommon problem.
there are some great projectors for 1k now, like the BenQ 1070 which I have seen on sale for 700, but it doesn't have the flexibility of the LCD projectors. I really like my Sony 55, but that was a lot more. I still greatly admire the Panny 2000 image.
