LG 2253TQ LCD monitor firmware, stored as a zip archive of about 91 KB. The name lists a 256 KB image and a Winbond W25X20, the 2 Mbit SPI flash memory that stores the scaler firmware on the main board. A good dump is what technicians reach for when a monitor shows no image, keeps blinking its LED or has a frozen OSD after corruption. Set the programmer to W25X20, back up the current chip contents before erasing, then program and verify the data to confirm a clean write.
