      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 ....

      MacBook Pro A2442 (Board No. 820-02443-05) – Liquid Damage Repair Assistance
      by rounin
      Device Information
      • Model: MacBook Pro 14” M1 Pro (A2442)
      • Logic board number: 820-02443-05

      Original Issue
      The device suffered liquid damage, causing a short circuit on the logic board.
      Near the audio jack area, the CR852 capacitor pad was severely burned, creating a clear short-circuit path. The board could not power on properly.

      Work Performed
      Removed the short circuit by drilling through the board (bypassing the short path) in the CR852 area.

      Current Status
      • When powered on, the screen shows support.apple.com/mac/restore....

      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....
