Firmware for the Samsung S20A300B monitor, with the name pointing to a Winbond W25X40 flash, a 4 Mbit SPI chip, and an S24CS08 EEPROM, which typically stores settings data. It comes in a small 323 KB RAR archive. Technicians program these chips with a CH341A or similar programmer to cure no-picture, blinking power LED or stuck standby faults. Keep a copy of the original contents of both chips before writing, and confirm the chip markings on your board match these parts.
