    Acer predator XB241YU Component identification

    Hello everyone,
    I have a problem with my Acer predator XB241YU screen. When I plug it in, the startup LED turns on instantly, and I can't turn off the screen without unplugging it.
    After disassembly and inspection of the electronic cards I found what looks like a broken inductor, it is marked with the letter A and is at location L58.
    In the first photo you can see the broken component, in the second photo you can see where it is on the board, in the third photo you can see the silkscreen and in the fourth photo you can see the identification sticker of the main board
    I couldn't find any schematics and wanted to know if anyone could help me identify the component and its characteristics in order to replace it.
    Thanks for your help

          It could be a Monolithic Power MPQ2143DJ

          Read page 12 to work out what the inductor value should be​
