backlight issue fuse has power

Hello I don't seem to have any backlight on this macbook pro the fuse is good I see no damage on the board , and I have even swapped screens over. is there anything else I could check before parting this thing out? The fuse has 11V going though it so it is not blown. but still no backlight.
