    M1 A2338 screen and touchbar issues after cleaning up liquid damage
    by jkruns
    Hello everyone,

    This is my first post after browsing this wonderful treasure trove of knowledge for many, many evenings. I've decided to learn how to fix these things, properly.

    My patient is an A2338 Macbook Pro M1 (late 2020).

    It had some corrosion around JT710 and JT700 caused by liquid spill, as well as against the protective barrier around the USB-C chips UF000 and UF100. So I took the main board out and cleaned it with a toothbrush and alcohol, then with alcohol in an ultrasonic cleaner. Cleaned the touchbar flex connectors as well. The board looks...

    MacBook Pro A2338 liquid damage repair for a beginner?
    by dbuergi
    Hi all,

    i have a A2338 with water damage on the logic board. Cleaning it showed some heavier corrosion around U7000 and surrounding caps. Some are totally broke.
    I get 5,2v when using both USB-C Ports but until now i didn't make any more tests.
    Since i'm a beginner i want to know next possible steps. I'm not afraid replacing the intersil 9240hi but the other parts with 1mm or 2mm scare me and i don't know where to get replacements.
    I fixed other laptops but this ist my first apple device ....

    A1466 Macbook Air (Liquid damage repair)
    by mon2
    Hi. Recently serviced a damaged A1466 Macbook Air. Thought to post the issues and resolution for each.

    Macbook AIR Model A1466 Diagnostic 09-01-2021

    Issue: Liquid damaged (beer spill) Macbook AIR will not power up.


    Problems & Resolutions

    1) Attached Apple magsafe power adapter. No green / no orange light. This confirms the absence of the PP3V42_G3H voltage rail. The PP3V42_G3H rail is the primary voltage rail necessary to communicate with the magsafe power adapter to report the green or orange light status to the end user....

    A2338 M1 Liquid Damage and WiFi dead
    by Agk007
    Hello everyone, I have a very interesting issue on this M1 i haven't seen on previous gen intel boards.So i'll give the back story on what happened to this mac. I purchased it damaged from a friend so i knew they didn't open it up. They spilled lemonade on the keyboard and it shut off. When i opened it up, there was surprisingly little liquid actually on the motherboard itself. Most of the damage was located in the LCD/Keyboard backlight area but even so, it didn't look that bad. I cleaned it very well but no components had to be replaced as they all tested fine (just checking for shorts/diode...
