Firmware for the Samsung S24B300BL monitor, with M236HGE-L20 in the name, which matches a 23.6-inch LCD panel model, supplied as a 145 KB RAR. Monitor firmware of this size usually sits on a small SPI or EEPROM chip on the main board and is rewritten when the screen shows no image, loops on startup or loses its menu. Use a suitable programmer, save the existing contents first, and make sure the panel and board match, as a different panel can need different firmware.
