Archive named for the Philips 24PFL5237 LCD TV, ZIP format, 2.41 MB; contents are not described in the name. Files of this size for TVs typically hold a main board flash dump, sometimes with EEPROM data. Extract it and confirm what each file is before using it. To reflash, use an SPI programmer and verify the chip type, capacity and board version match your unit. Always read and save the existing chip contents first so the set can be returned to its original state.
