Firmware for the LG 24MP58D monitor, chassis LM69A, main board EAX66805311 revision 1.3, packed in a 441 KB RAR. LG uses EAX part numbers for its main boards, and the revision suffix in brackets should match the label on the PCB. Such a dump is used to reprogram the scaler flash when a monitor shows no picture, stays in standby or loops at power-up. Write it with an SPI programmer after saving the original contents, and confirm the chip size matches the image.
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.
