Try disconnecting the AC power cord. While pressing "Menu" button on the front of the set, connect the AC power cord. Use the channel up/down buttons for selecting the service number. Use volume up/down to change the value.
Press "Menu" button again to exit the service mode.

Try above procedure... I found it from Internet....
