Have you changed the menu in the BD-P1600 to output to HDMI after watching it with the composite cables?
I recently purchased a BD-P1600 and tried to set it up on my Olevia 242T FHD LCD HDTV. When connecting to the TV via the A/V cables included with the Blu-ray player, everything works fine. When trying to use the HDMI connection, the video has come color distortion/noise but the audio is fine.
The output has psychodelic colors on all menus/movies. I've read several posts that say it would be the TV not supporting HDCP, but this is from the TV manual/website: "Digital Input - 2 HDMI w/HDCP". I get the same results on both HDMI ports.
The HDMI connection works perfectly when I hook up my laptop, just not the BD-P1600. I'm hoping there is an easy fix so I don't have to deal with the hassle of exchanging it for another unit.
