LG E2050S monitor firmware in a 380 KB rar archive, most likely the image of the scaler board's SPI flash. It is used when the screen stays black, the power LED blinks or the firmware is corrupted after a power surge. Programming is done with a standard SPI programmer such as a CH341A, with the chip removed or clipped in circuit. Before flashing, check that the chip size matches the file and read out the original contents. Board revisions can vary, so compare the main board markings.
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.
