Master firmware for the TSUM based scaler in the LG W1941S monitor, version V130, checksum A4C5, dated by code 081007. Packed as a RAR of roughly 54 KB, it holds the complete image for the serial flash beside the scaler IC. Repair shops reach for such a file when a monitor powers on without image or reboots repeatedly. Before writing it with a CH341A or similar tool, save the current chip contents, check the chip capacity and confirm the board revision and LVDS type match the unit.
