    34UM68-P , LG monitor schematic / part ID help please

    Hi all

    This monitor not powering with white front LED on .

    Discovered buck converter IC403 to be faulty . It's marked IAEDH .

    PIN 6 ( GND ) measuring S/C with PIN 5 ( 1V8 O/P )

    The 1V8 supplies the CPU , which hopefully hasn't been damaged .

    Package type i believe is SOT23-6 , but could do with some help to ID device .
