    MacBook Pro M4 16" A3403 on the table with water damage

    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 GermanyClick image for larger version Name: PXL_20250713_170230177.jpg Views: 128 Size: 1.96 MB ID: 3681457

      I'm a little late to your question but in case you still need this, it measures as 10nF

          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 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?...

          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

          D8410
          and the resistor R8431

          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...

          Macbook A1708 with water damage and problems after removing U2800
          by dbuergi
          Hi all,

          i got a A1708 with water damage. I cleaned everything and the board started normal. But the next day i got 20v but no booting. Thermal cam showed over 160c (never had a chip getting this burning hot before) in U2800 and some shorts on the caps around it. After removal shortages were gone and i installed a donor U2800 which worked before.
          Sadly now the device stays at 5v, 0,4a and 1,9w and i don't find the problem.USB ports worked fine before....
