In some cases it is possible to reset the data within the NVM using the procedure
outlined below.

1.  Connect a test pattern to the antenna terminal.
2.  Tune the receiver to this signal.
3.  Turn the receiver off using the mains switch.
4.  Press the volume down and channel up buttons on the front of the receiver at the

same time.

5.  Keeping these buttons pressed, turn the mains on.
6.  When the set starts up, it will be in the service mode.
7.  Release the buttons.
8.  Go to the NVM page/position/value mode and change the following data.

This procedure will reset certain areas in the NVM by returning certain locations to 00.
This will result in the adjustment data being incorrect, so it will be necessary to set up
the geometry and user menu’s (tuning, picture and sound).
