Firmware dump for the LG L1755ST LCD monitor, zipped to roughly 81 KB. The name shows a 256 KB image and a Winbond W25X20 flash chip, a 2 Mbit SPI memory that keeps the scaler program. Reprogramming it can revive a monitor that shows no image, fails to leave standby or has a locked menu caused by damaged firmware. Connect an SPI programmer to the 8-pin chip with the board unpowered, store a backup of the original read, then write this image and confirm with a verify pass.
