Second copy of a TSUM scaler master image for the LG W1941S LCD monitor, firmware V130 with checksum A4C5 and date code 081007. The archive is about 54 KB and contains the flash image for the main board controller. It serves for recovering monitors with no backlight, no OSD or a frozen power LED caused by bad firmware. Program it into the SPI flash using a programmer, read out and store the existing data beforehand, and compare the checksum with the one in the name after flashing.
