Firmware package for the LG W1941S monitor built around a TSUM series scaler, labelled V140 with checksum 7DD3 and date code 081022, marked as a master image. A master file is normally the full flash content written to a blank or corrupted chip on the main board. Technicians use it to revive a dead or blinking monitor by reprogramming the SPI flash with an external programmer. Verify the checksum after writing, keep a backup of the old dump, and make sure the board and panel version suit this release.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
