Welp, I think my LCD backlight has failed (pretty sure given the symptoms). Yesterday it started to flicker heavily and then over night it's gone dim (almost black -- I can faintly see things). I've hooked up a cheap, small (emphasis on small) 12" external for a quick fix but I suspect I'll have to get this fixed. I've replaced LCDs on IBM 390Es and 390Xs but never opened up the actual display. Does anyone know where I might get diagrams of this toughbook that might help me?
