Firmware dump for a Samsung SyncMaster B2245 monitor, with the name pointing to a 25X40 type SPI flash chip, a 4 Mbit (512 KB) serial memory common in display scaler boards. The 114 KB RAR is used when a monitor shows no image, stays in standby or loops its logo because the scaler firmware is corrupted. Desolder or clip the 25X40 chip, read and save its original content with a programmer, then write this image. Confirm the main board version matches, since different panel variants can use different firmware.
