Hello!

I have a C740 Chromebook and the screen's backlight is not turning on.  The image is faint on the screen, but will not light up.  I've attempted re-seating the cable behind the screen, on the motherboard itself, tried a different screen and cable altogether, re-connected the battery, and all give the same result.  Is this a problem with the motherboard / are there any other fix attempts I should be made aware of?

    Yeah, although many older systems had the back light controller as a separate little board mounted under the display, it looks like they're building that function into the MB these days...
