Hi Randy,
The only thing you can try is to restore the DMP to factory default.
This can be done by keeping the RESET button on the back of the DMP pressed for at least 10 seconds. You should hear at least two "beep" in a row when doing so, if you hear only one it means that the DMP is rebooting but not restoring to factory default.
It this doesn't help then I'm afraid you have a nice new bookend
Regards,
Nicolas
