SCHNEIDER _ 29M432 _ SERVICE MODE _ ADJUSTMENTS





  1. Before activating service mode, supply appropriate test picture. Set brightness, contrast, colour, contour and tone to medium values.
  2. For geometry alignment a 4:3 test picture conforming to standards is required.
  3. 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 EXITkeys consecutively on the remote control (RC), while TV is running.
REMOTE KEY FUNCTIONS IN SERVICE MODE

Red        key one line down

▼          key select previous menu-table
◄/►     keys change values
OK      key save the changes
EXIT     key exit Service-mode

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.
