Firmware dump for the Samsung S23B350T monitor, read from a Winbond W25X40 SPI flash chip, which holds 4 Mbit or 512 KB, consistent with the archive size. Monitor firmware faults show as no picture, boot loops or a dead power LED, and rewriting the chip with a programmer such as a CH341A often cures them. Clip or desolder the 8-pin chip, save the existing contents first, then write and verify. Check the main board version against yours, as panel settings may vary.
