- Before activating service mode, supply appropriate test picture. Set brightness, contrast, colour, contour and tone to medium values.
- For geometry alignment a 4:3 test picture conforming to standards is required.
- For 16:9 TV-sets a 4:3 test picture must be adjusted to a full-covering picture in panorama-mode.
TO ENTER SERVICE MODE
- To enter service-mode press[ MUTE => Red key and EXIT] keys consecutively on the remote control (RC), while TV is running.

SERVICE MODE SETTINGS
- Version number: shows the implemented software version. For new initialisation of the NVM values, without changing the geometry settings, change the version number, save, exit service mode and switch the TV-set off and on again.
NVM reset: initializes all NVM values of the Eeprom IC906 including
geometry values.
Set value to ON, save, exit service
mode and switch the TV-set off and on again.
Prior to the initialization it´s
helpful to write the service mode parameter values into the alignment table.
After initialization all service-mode settings have to be checked and readjusted if
necessary.
