Clean the residue off the board and the ic, it may still be ok, plus you can read the number better.Comment

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....09-01-2021, 09:31 AM -
Hello everyone,
I am new into this, sorry to post it here. I want to make this as a pet hobby project, as this mac is not urgent.
I have (Macbook Pro 13inch 2017mid) A1706 820-00923-A
My mac had liquid damage a long time ago, the connector from J8500 is damaged on pin 46 (PP5V_S0_ALSCAM_F), I guess the LCD/display panel is in short circuit, as I saw the connector from the LCD burned as well.
And the resistor L4004 is literally burned.
From what I see from the schematics, it does not affect any other rails, only the connection to the display... -
Hey everyone,
Had a MacBook pro 13" 2018 (A1989) come in for liquid damage. The only liquid damage was all around UB400. It was most likely soda, so there wasn't that much corrosion. I reflowed the UB400 and the QB chips with some flux, and replaced the caps/resistors that were in bad shape. Seemed to be working fine at first, but the next day when testing it again, the laptop charges and boots fine, the CPU would overheat, and U7210 would get to 70 degrees Celsius as well. I'm testing with only screen and battery connected at this point.
I can't figure out how... -
Got a MacBook Pro M1 Pro 16'' to rescue immediately after liquid accident - I got it in less than 30 minutes after the spill.
It got spilled from behind when the laptop was closed. It mostly affected the rear of the mainboard and the bottom of the LCD.
I quickly took it apart and washed the liquid residue off the mainboard.
The area around the UP800 had some light corrosion, but it just washed away with some IPA. Other areas looked undamaged.
The mainboard got a thorough cleaning, as did the top case and LCD connectors / cables.
Now the laptop... -
