I am experiencing problems using the following unlocking code. Does anyone have any ideas where it is going wrong??? I get to the password bit and nothing happens. Sanyo DVD Player Multi-Region Codes for Sanyo DVD-SX25 1. Main Power ON. 2. Confirm that "NO-DISK" was displayed on the display panel. 3. The control key of the "display" of remote control is pushed and select to "Video". 4. Input the password "1,3,5,7" by the remote control. 5. Confirmation screen for the version of the firmware. 6.The region code is changed into 0-6 with the "up-down" key of remote control. ("0" is free. And, "2" is standard for Europe) 7. Push the "up-down" key of the remote control. 8. Finally, the control key of the "display" of remote control is pushed again.
