Basics EEPROM Settings - 11
EEPROM Settings Caution:
To prevent data loss or corruption, always save
EEPROM settings before you replace the microprocessor
board.
See Troubleshooting for instructions on saving the EEPROM
settings from the old microprocessor board and restoring
the settings on the new microprocessor board.
If the settings are lost before they can be written to the new
EEPROM, the display will be impossible to repair, and the
whole display will need to be replaced.
