  • [SOLVED] 820-2936-B Chimes, backlight, no picture. (L9080 blown)

    So this laptop chimes, has a backlight and the caps key lights up when I tap it, but it never gives an picture. The screen is just black with the backlight on.

    I have tried all the usual things like a PRM reset. The external screen doesn't seem to work either, but I am checking with a new HDMI cable tomorrow.

    Can someone give some initial direction to get me started please?

    First try a known good LCD assembly of course. Then check all LVDS lines on diode mode. Damaged L9080 is common.

      L9080 had broken trace.

      Thanks again dukefawks.

      Close and mark as solved please. (There's a type in the subject model number too, while you're editing. Will help others find it if it's right.)
