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

Details:
Model : HP OMEN 17-an012nf
Motherboard Part Number : DAG3BAMBAF0 REV : F
Serial Number (S/N) : 5CD7280D51
BIOS chip : Winbond W25Q64VSIQ
Programmer : EZP2023+
