Archive for the Samsung PS50B550T4 plasma TV, assigned to main board BN41-01188C. The name gives no chip or content type, and its 17.2 KB size suggests a small memory dump such as an EEPROM or SPI flash image rather than a complete software package. Repairers use such dumps for boards that will not power up, lose settings or show errors after component work. Inspect the archive to find which chip it is for, confirm the board number and revision letter, and back up your original memory before writing.
