Out of the box, the BD-P3600 is set to 480 resolution. If you're hooking it up via HDMI, you first need to hook it up to the TV via composite cable (included in the U.S., I'm not positive about the region you're in - but if there is a supplied cable use that). Then, go into the Settings and change the output and resolution in the Setup and Video menu.
