Firmware for the Samsung 933SN monitor, model code LS19CMYKF, with ZN likely being a region suffix, in a 102 KB RAR. Monitor dumps like this restore the scaler EEPROM or flash when the screen shows no picture, flickers or will not leave standby. The name does not state the chip type, so check the marking on your board and confirm the image size matches before writing. Program it with a common EEPROM or SPI programmer, and read and save the existing contents first so the original can be restored.
