    MacBook Air 820-01521 Dead (Water Damage)

    hi everyone, customer came with a MacBook Air 13 Retina 2018 820-01521 dead, she dropped some tea on it.
    i found corrosion on U6960 and U7650, i already replaced.
    On USB Meter i have 5V 0A.

    PP3V3_G3H_RTC = 0.800V
    P3V3G3H_PHASE = 0.800V
    PP3V3_G3H = 0V
    PP5V_S5_LDO = 2.5V
    PPBUS_G3H = 12.33V
    PP3v3_UPC_XA_LDO = 3.3V
    PP3v3_UPC_XB_LDO = 3.3V

    I also tried to restore it using a 2014 Macbook air but no DFU device found.

    Thank you.

    MacBook Air M4 A3240 Brand New Water Damage no Image
    by Ugur87
    I have a brand new 13.6-inch MacBook Air M4 that was only used for three days and now has water damage. A glass of water was spilled over it. I examined the motherboard and there was only water next to the display connector. I cleaned it with isopropanol and the components look clean. The MacBook obviously turns on and draws 20 volts from the power supply. The keyboard backlight comes on, but the display remains black. Where should I best start? Even when I shine a light on the display, I don't see any image. I have all the tools I need, including an infrared camera. Where should I best start?...

    MacBook Pro M4 16" A3403 on the table with water damage
    by TimSinger
    Hi guys,
    I have a MacBook Pro M4 16" A3403 on the table with water damage. I allready found the problem within a bad cap. As far as my researh went, I couldn't find the schematics and boardview for this MacBook model. They seem not to be released now. So my question is if anybody has a working A3403 on the table and could tell me, which specification this capasator has?
    I attached a photo of the missing cap. It's on the bottom side of the logicbard.

    I am very thankful for your replys.
    Thanks in advanced and best regards from Hamburg Germany...

    Macbook A1466 820-00165A heavy water damage but working with "flashing" screen
    by dbuergi
    Hi all,

    i got a A1466 with serious water damage. I was able to clean the whole board and only found a fuse with a coroded trace. Cleaning and resoldering did the job and the macbook started normal but after some time the screen began "flashing" like turning on and off while the Macbook was still running. I checked the board again but was not able to find the problem until now.
    Any ideas where to look?...

    Macbook Air A3114 5V 0.0A after water damage
    by s_henya
    Hi Mac experts :-)

    Im usually not getting too many Mac logic boards repairs, (mostly PC laptops)
    This Mac isn't powering on not boosting to 20v, stays at 5v with 0.0Amps.

    Took out the board and it suffered some water damage, see attached pics.
    All cleaned with IPA but due to long time with corrosion something already got shorted...

    any advice on the below:?

    1. Looking for relatively safe location for voltage injection as all of the caps around that area has 0.0ohms resistance.

    I tried injecting 0.5v on one of the caps...
