                  If another compatible BIOS doesn't work (as expected) make sure, all voltages are present which are supposed to be present, so check the voltages of all coils.

                          🛠️ 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
                          ...

                          SF314-41 BIOS without internal display
                          by lanovey
                          Hello there,
                          I have a SF314-41 motherboard that i bought impulsively recently, the problem is that i only bought the motherboard only, nothing else. When i tried powering on the board with 19V (soldered on the DC IN port), and then shorting the pin 1-2 of the keyboard, the board is turning on (as indicated by the fan), however it seems like the board is displaying on the internal display as connecting to a display on the HDMI (external) does not display anything.
                          I tried connecting a USB keyboard, the keyboard is powered on, however pressing numlock do nothing (supposed to toggle...

                          Suspected Windows updates contained BIOS update in which, during update the Desktop PC displayed a black screen to the monitor while still powered on. Display image never restored.
                          Tested RAM in both slots, as well as new RAM. Tested a brand new known working i5-10th Gen GPU (Same CPU as original installed). Cleared CMOS. Tested the Desktop PC with a dedicated GPU connected, but still no display. Device will not POST when powered...
