    Schematics/boardview or help identifying component GA40IV-BR9N6 (60NR03F0-MB3220)

    I just replaced a cracked screen on this device, and it seems the replacement screen has blown out a component that I initially thought was a fuse. I say initially, because I came across this post which seems to be the same component I am dealing with: https://www.badcaps.net/forum/showth...=GA401IV-BR9N6

    And also this post on another site: https://rog.asus.com/forum/showthrea...ark-fried-chip!

    TLDR; A user on that thread posted this for his Asus N550JV "Looks like in my case it's an SMD ferrite inductor (3A/120 Ohm/190 Henry/100 Hz/0603 series"

    I say the replacement screen was responsible for this because when I reconnected the original screen and bridged this component (thinking it's a fuse) the backlighting came on for the cracked screen. When I repeated this with the replacement screen, I got sparks which further damaged the component.

    Here are pictures of the component. Sorry for bad quality pics of screen, I didn't have an SD card in the usb camera at the time, and now the component has fallen off.

    Another question... worse case scenario, since bridging this like a fuse brought back functionality... with a proper screen, would it possible to just bridge the pads with a wire?

    I don't know what the burnt component is, but the fuse is the Polyfuse marked P1524, that burnt component is likely a low value resistor or inductor. If a piece of wire restores operation, you should be ok
    Your replacement screen may use different pin connections or have a problem.

      I also think the same. Even though not recommended, a poly fuse or inductor for backlight can be replaced with a jumper wire at least for testing. The fact that your old screen worked but the new one caused burning must be either an incompatible screen or a damaged one. Sometimes connecting display panel with battery pack present can cause short circuit in the panel too. Let us know the part no of both screens so we can verify whether they are pin compatible in the first place.

        Thanks for the replies. Here's a pic of the labels for both screens.

          I have an Asus that when I change the screen, it works correctly in a week and then it stops giving an image
