Asus K555L Board X555LD

[Sergio Kub]

Hello,
I have an Asus K555L notebook, X555LD board at work and having trouble fixing the defect.
Looks like the computer works, but it doesn't have back light.
Main voltages Ok.
Tested Memory Ok.
In D4501 Bl_EN is 0V
Can anyone give any tips?
thank you in advance

I think these computers with little technical literature are beyond repair.

Why do you not check if the lcd connector got his 19v and 3,3v on the lcd connector. Are you sure the board post to confirm that you can use an usb keyboard and toggle the capslock or numlock and see the light lights up.

Good luck

These voltages are present at the LVDS connector, only the BL_EN is missing.
I'll try to re-record Bios,
Thanks
