Ask Acer Nitro 5 AN515-55-57WU | FH51M LA-J871P Rev:1B

[magnusp]

Hello,

I need help with an Acer Nitro 5 AN515-55-57WU.

Motherboard: FH51M LA-J871P Rev:1B

Problem:
Laptop powers on but no display.

Symptoms:

• Power LED stays on
• Keyboard backlight turns on
• Fans spin for about 5 seconds then stop
• No display on internal screen
• Same behavior with RAM installed or removed

What I already tried:

• Read original BIOS with CH341A and made backup
• Flashed several BIOS dumps (16MB) including:
  • FH51M LA-J871P REV 1B working BIOS
  • another BIOS provided in another thread.
• Erase / Write / Verify all successful
• Reset EC and CMOS
• Tested RAM in different slot

Result is always the same: no display.

Could someone help check my original BIOS backup or provide a confirmed working dump for this board?

I attached my original BIOS backup.

Thank you.
