Thinkpad P51 20HH Schematic/BoardView pls.

[cheeseandjamsandwich]

Hi all,

I have my Lenovo ThinkPad P51 20HH laptop with a dead backlight.
It's a Xeon E3-1505M v6

Need to track down the fuse that's blow... the one fuse next to the 40-pin hasn't blown, has continuity... Picture is visible on the panel with the help of a flashlight.

Thanks in advance!
Rich.

This looks to be correct.
Thanks!

I have a few more days processing to do and then i'll open her up.
Looking at the schematics, F7 & F6 are the LCD/Backlight fuses it seems. I remember seeing F7, as it's right next to the LCD connector, and it had continuity.
Will see what the other one says, and see how the old panel test as per Vesko356's suggestions.
