EEPROM dump for the Samsung UN40EH5300G LED TV fitted with an LK400D3HB7K panel. The name gives no main board number or chip type, so confirm the EEPROM marking on your board before using it. Such small files store configuration, option codes and panel settings, and rewriting them can cure wrong picture or start-up faults caused by corrupted data. Read and save the original EEPROM first with an I2C programmer, and expect to recheck service menu options afterwards.
