    macbook pro M1 a2338 820-02020 water damage

    Small water damage, cleaned it.
    Shorted CL002, i removed it carefully with soldering iron, now it has voltage.
    5v instant 180ma and then 100ma stable. I didn't found cycling voltage nor shorts in the motherboard.

    I don't have pp5v_s2 because uc300 does not get enable pin from u8100 (it gets VIN). pp5v_s2 is not shorted, nor enable pin line.

    PP3V3_S2 OK
    PP3V3_S2_UPC OK
    PP1V5_VLDOINT_MPMU OK
    PP3V3_AON OK
    PP1V8_AON OK
    PP1V25_S2 OK
    PP1V8_S2 OK
    PP1V8_S2SW_VDD1 OK
    PP3V8_AON OK

    u8100 did not have corrosion at all so i give it a little chance of fault.
    All fuses ok, both type-c tested on both sides.

    Any ideas?

          What is the voltage of PPBUS_AON ?

              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?...

              so I’ve a2289 with water damage ! In first time other friend have clean and work ! But after some time stop working !
              now, I open the MacBook and I see a lot of corrosion near backlight circuit (I attach some photos about that ) I think the problem is on backlight maybe bcs do strange boot then reboot (attach video ) I change some thing on the circuit like :
              q8400
              q8401
              D8410
              and the resistor R8431

              if I check PPVIN SOSW LCDBKLT_R I’ve 12,9v
              on...

              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...
