    Samsung UE43AU7172UXXH BIOS

    Mainboard Model: KANT_SU2E_AU7000 Rev: 1.2 (BN9654206U)
    PowerBoard: KANT_SU2e_43_HYBRID_PW Rev 1.0

    Power board seems to be working when i unplug mainboard backlight comes, but with everything plugged in, i get standby light, when i press powerbutton, the standby light very slowly flashes 5 times and then it stays on again. I suspect bios might be corrupted. If anyone could check and repair that would be great.

    Just an update, i've replaced the mainboard for a new one and the TV is working, after some measurements i think this firmware is functional and issue was elsewhere.

      Samsung Series 9 - BIOS issue
      by Kjell
      After installing Linux, I can no longer enter the BIOS of my Samsung Series 9 (NP900X3C) laptop. When pressing [F2] during boot I simply get a black screen. Same thing when pressing [F10] and choosing "Setup" from the "App Menu" tab. Apparently this is a relatively common issue with Samsung laptops of that generation, but unfortunately i haven't been able to resolve the issue (yet).

      Things i've tried so far; reinstalled Windows 10, checked for redundant boot entries, tried to factory reset using the emergency keyhole, attempted to clear the NVRAM by physically...

      🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
      by macabook
      Hello everyone,

      I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
      🧩 Initial Issue
      • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
      • External display (HDMI) shows

      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:

      No Standby Light on Samsung UN65MU6300FXZA with Mainboard BN94-12440E
      by Michael Long
      I had a Dead Samsung UN65MU6300FXZA with Mainboard BN94-12440E
      Dead / No Power / No Standby Light results after power company had three
      consecutive power outages on/off/on/off/on/off after which TV was rendered unresponsive.

      After exploring the issue found Mainboard was the fault. Then with research on this site determined IC1604 was the suspect. The IC1604 is a surface mounted device (SMD) EEPROM, Winbond Model 25Q40CLSIP. A read on this EEPROM came back with all FF FF FF FF FF in all registers blank and empty of data. I had a spare mainboard with intact IC1604 and utilized...

      Hi all,

      When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
      (I've tried removing the battery and resetting the device, but the issue persists.)
