Firmware read from the W25X40 flash chip of an LG 19EN33SA monitor, marked as read OK and packed in a 180 KB RAR. The W25X40 is a Winbond 4 Mbit (512 KB) SPI flash, so the image should match that size. Such a dump restores a monitor that stays black, flickers the power LED or has corrupted settings. Write it with an SPI programmer and a clip or after desoldering the chip, and keep a backup of the original contents before erasing.
