Firmware dump set for the Samsung S20A300B LCD monitor, covering two memory chips: a Winbond W25X40 SPI flash and a 24C08 serial EEPROM. The W25X40 is a 4 Mbit (512 KB) flash that normally holds the scaler program, while the 24C08 is a 1 KB EEPROM storing settings and often EDID data. Technicians write these images with a programmer such as a CH341A to cure no-power, no-picture or boot faults. Make sure each image matches the chip size, and back up the existing contents before overwriting either part.
