Firmware dump for the LG W1954SEV LCD monitor, packed as a zip archive of about 90 KB. The name gives a 256 KB image size and a Winbond W25X20 serial flash, a 2 Mbit SPI chip that commonly holds the scaler firmware on monitor main boards. Technicians reflash this chip when a monitor shows no picture, cycles its power LED or ignores the buttons after firmware corruption. Read and save the original contents with a programmer such as a CH341A before writing, and confirm the chip marking on your board matches.
