First post on this awesome forum, so hello everyone :D Screen of my T430 went black. I've checked LCD/backlight fuses - all ok, but theres no voltage at VCC3P/F3 and no voltage at Q22 mosfet gate. First thought - might be faulty mobo, but after checking another board problem remains. So what else could be causing it? Lid sensor? Screen itself? Any guidance will be appreciated.
