    You only need a piece of software you can download from Samsung's website to get your monitor back up and running again. Instructions are in the above mentioned threads.

        You need to install the driver before you can instal the firmware.

                      Doesn't the firmware file come with the update utility?

                          What's the EEPROM size? I downloaded the firmware updater program, and ran universal extractor on the updater utiity. It found some 512KB files that in a hex editor, look suspiciously like a monitor firmware image. BUT I have no idea if they are correct or require some kind of editing first.

                          If you can backup your EEPROM and compare with these, maybe they are correct. There are 69 of them though....

                            Thanks , i will backup tomorrow EEPROM , but when make backup at FLASH IC401 25X40BVSIG , will not save one .bin file ?

                            Or when i save .bin file, then use "universal extractor" and see how many files are, or compare each file size ?

                              You will get only one .BIN file when you backup the EEPROM.

                              I ran universal extractor on the "FirmwareUpdater.exe" file that comes with the SamsungFirmwareUpdater program, which resulted in the extraction of some 69 potential BIN files, and I don't know which one you should flash, or if they are even valid firmware images at all.

                              It looks like the size is right though, since you have a 4Mbit chip.

                              After you backup the EEPROM, can you upload the resulting file here?

                                  You don't need to extract anything from main.bin. Main.bin *is* the firmware image.

                                  I just want to compare it to the ones I found in the SamsungUpdater, see if they are plausibly correct.

                                    But did you run the update anyway since the firmware may be corrupted?

                                      I looked at your file, and a few of the ones that came from the updater utility, and comapared in a hex editor.

                                      The files are the same length, and the overall structure of the files is similar, and many blocks of data match up, although some data which match are shifted a few bits and some data is different. I don't know enough about this kind of thing to say why that is.
                                      Maybe some is config data which will change depending on user settings? I don't know.

                                      I don't know why there are 69 different files in the updater - I can't imagine there would be 69 different versions of this monitor, so I don't know why there are so many there. They aren't all the same as each other, that's for sure.
