    ASUS S55LB no backlight

    Hi Guys,

    Alright so I have an ASUS S55LB and i've just replaced the LCD and made the ol 'forgot about the battery connector' mistake. This is a touchscreen model and if I look at the screen with a light I can still see the display faintly and the touchscreen is still functional but of course...no backlight, I can confirm it was working beforehand.

    I've had the mobo out and the only thing that I noticed that was strange was a resistor marked 0 that was a little out of place and had no continuity. At the recommendation of a similar thread I have since taken this part off and put a bit of solder to link back up, it now has continuity but still no backlight! (I am aware it's not the best solder job so i'm not ruling this out)

    I've taken a few pics of the top and bottom sides of the mobo around the LVDS connector area in the hope that someone might be kind enough to have a quick look and see if i'm missing something. There are a few parts that i'm not 100% sure of and they don't seem to be marked so I've circled one on each side...are these fuses? Any help would be much appreciated!

    Cheers.

    check for fuses around lcd connector, its possible just that you burned some when pluging lcd

      check those parts that you circled have one side connected to ground in that case they are capacitors, if not then they could be coils

        it looks like a coil not a resistor so you can change it just to the same coil

          in a second picture the element sitting by a lvds connector take one side of it not to be connected and check the resistence
