ZIP archive of 318 KB carrying firmware for a device identified only as W1642S, a code that resembles an LG Flatron monitor model, though the name itself gives no brand, scaler or board number. Unpack it and check whether it holds a scaler flash image, an EEPROM dump, or both. Before flashing, confirm the main board and the chip marking on the PCB, back up the existing contents with a programmer, and make sure the image size matches the memory chip, otherwise it will not fit or the monitor may stay dark.
