              After reflash the EFI still have the same issue. I decided to replaced the CPU voltage regulator U7400 turn on then killed the CPU.

                I need a BIOS dump for the Samsung S49CG934SU monitor
                by Habble7
                The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

                Suspected Cause:
                I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

                Troubleshooting Attempts:

                DUMP DVR HIKVISION DS-7208HGHI-K1 (80389 Rev 1.3 Firmware)
                by Mephysis
                Hello guys i really need help, i recently updated my DS-7208HGHI-K1 and it somehow got bricked, I've got it up and working now by flashing a new dump file i found but the serial number is really wrong and the uploader of the dump file probably intentionally did it.

                I still have the bricked dump file is it possible to transfer the serial number of the "bricked dump" to the "working dump"?

                [REQUEST] 2MB BIOS Dump for Lenovo NM-E471 Rev 2.0 (Winbond 25Q16JWSIQ Chip)
                by hyperwood
                Hi everyone,

                I’m looking for a 2 MB BIOS dump for a Lenovo IdeaPad 5 16ARH7H / Legion 5 with mainboard NM-E471 Rev. 2.0.

                The BIOS chip is a Winbond W25Q16FW (1.8V, 2MB) and it's completely unresponsive / bricked. I tried recovery via USB but no success. Now I want to reflash it externally using a CH341A programmer.

                I already found 32MB dumps (e.g. from Vinafix and Badcaps), but they are too large for the chip – and the last 2MB in those files are just FF FF FF....

                āœ… What I need:
                • A working 2MB BIOS dump
                • Matching NM-E471 Rev. 2.0, e.g. JY575
                ...

                Power supply Manson NTP-5561 (5661) LCD controller dead - PIC18F87K90 HEX dump required
                by Andreas_de
                Hello!

                i got a damaged Manson NTP-5561 (60V, 1,6A DC output) and and the main issue is that the controler IC for the LCD display has a short. The controler IC PIC18F87K90 is mounted on the back of the back of the LCD. Vss-Vdd = 3 Ohm. The 5V and 3,3V power line was killed as well, but that is not a problem. A new LDO 3,3V and 5V 7805 is already ordered.
                Replacing the PIC18F87K90 is necessary but that makes no sense without having the HEX dump of the new controler.

                Does anybody have such a power supply and could do a HEX dump of the Flash and EEPROM memory?

                Anycubic Photon 5.5 3D printer 25Q32 flashrom dump needed
                by re-atari
                Hello all, as the title says, I'm very much in need of a valid firmware dump of a Anycubic Photon 5.5 3D resin printer. It's stored in a Winbond 25Q32, so it's 4Mbyte.

                Here's a little background for my request. A few weeks ago I bought this 3D printer from a guy who had moved on to a PLA printer. I got it at a vey reasonable price, as it was in a defective state. The seller told me that he had experienced a power failure during a firmware upgrade, after which the printer appeared to be dead. He thought the firmware was corrupted in such a way that the printer was now bricked. As he...
