    Need some components reference for Dell U3419W burn power card

    Hello.
    The power supply board for my Dell U3419W monitor is faulty. The Mosfet Q621 (60R160P6) has burned out (shortcut), but the problem is that other components have also burned out, and I don't know their part numbers. I haven't been able to find a schematic or photos of the board to identify them (the part number is 4H.47A02.A00).
    The faulty components are resistors R631, R641, R627, R632 and chip IC621.
