Player freezes when powered on.

During the middle of a movie my video connection was lost and a message appeared saying "incompatible video signal. check output video settings." I stopped the player and shut the power down because I couldn't get a video signal. When I turned the player back on the words "power on" displayed and then the player freezes. I can't do anything past that point with the player or remote. I can hear the disc spinning and then nothing. I'll unplug all systems and then restart my player again only to get the same result. To sum it up, the power turns on and then the player freezes immediately. Please help
