    Hi ngvuanh!
    Glad to see you're back.

    VAIO VPCSA3L9E

    Yes finally I did replace the wrong LCD spare for a new one that works. But I also got a new problem, no sound and no lan network.
    I've checked all drivers setup, everything is well installed and up to date but I got no sound at all, not inner speakers nor headphones. I don't care that much about LAN Ethernet as I have working Wi-Fi.
    I disassembled the whole thing twice but found everything well connected, I also changed win10 to original win7
    I'm afraid there could be another blown fuse or I could damaged the motherboard when bridging the fuse.
    Today I'll dissasemble it again and use a better magnifier to check the soldering area.

    Any clue will be well received

    I'm not sure this is fuse related if not sorry for the off-topic

    So I purchased a defective Vaio Pro 13, which would not display anything on the screen, however the HDMI output works.
    I purchased a whole new screen assembly in the hopes that it would work, however still nothing. I took a flashlight and found that it was the backlight which was dead. I know how to solder, and have no problems with a multimeter, however I have never fixed a backlight fuse before, and I have no idea where the fuse is positioned. I took a picture of the display connector and the area around it, does anyone know where the fuse is? And could I just remove the fuse and solder between the pads to short it, to make it work?

    It's been long time checking this forum. Sorry for late answers.
    @jacobtc, the fuse is a little one with letter S on it. You can bridge it or remove and short 2 pads are which ever best for you.
