Firmware dump for the ASUS VS228DE monitor, taken from the main board using a TSUMU19AR6-1 scaler controller and stored on an MX25L2026D SPI flash, a 2 Mbit (256 KB) chip. Packed as a 140 KB ZIP, it is used to recover monitors with no image, a dead backlight or a corrupted menu. Program it with an SPI programmer such as a CH341A, reading and saving the existing chip contents before erasing. Check that the scaler and flash markings on your board match those named here.
