    820-01827-A - Sudden death - 19V missing all USB-C port

    PPBUS_G3H to the three big coils(0.02) = 0.05 I've added SSD pics.

    A2179 / Board 820-01958 - liquid damage, 5v- loop 54 -0 54 ma

    Thanks. By right side, I meant on USB-C connector side. nothing on audio/jack board Diode mode to ground at 3V3_G3H_RTC = 0.400

    820-01827-A - Sudden death - 19V missing all USB-C port

    I've measure all. You think I should find a coil open ? What do you mean by "the marked point is connected to PPBUS_G3H" ?

    A2179 / Board 820-01958 - liquid damage, 5v- loop 54 -0 54 ma

    Hi, I got this board, water on the right side, not on CPU side, corrosion on recto/verso. I get PPBUS_G3H = 12.27 PP3V3_G3H_RTC = 0V Thanks Sam

    820-01827-A - Sudden death - 19V missing all USB-C port

    I did Big coils. Need to do medium one (in blue) ? I said U7000 as those components are all to GND trough U7000.

    820-01827-A - Sudden death - 19V missing all USB-C port

    Thanks. So shorted to GND by U7000. Need to replace that chip. Anything else to test before ?

    820-01827-A - Sudden death - 19V missing all USB-C port

    according to boardview this could be U7000, looks different compare to what I watch on video.

    820-01827-A - Sudden death - 19V missing all USB-C port

    Boardview is not exactly same my board, I am not sure which one is U7000. Is it always IC ISL6259 QFN32 6259AHRTZ 9AHRTZ ?

    820-01827-A - Sudden death - 19V missing all USB-C port

    thanks. I get nothing on both. Diode mode to ground = 0.25 USB-C chip not talking to charger ?

    820-01827-A - Sudden death - 19V missing all USB-C port

    Hello, I got this A1990, sudden death, no 19V on all port. I've disconnect battery and charger and focus on big coil value to ground (in blue on the pics). I will user 820-01041 in boardview Thanks Sam
