The board has gotten wet, you can see it in the pictures. The display stays dark! No backlight. I think I have to bypass the front of the needle point too? Unfortunately I don't have a board view for my A2338! Is there a chip in the picture for the backlight?

by bigbadbiosHi,
I am trying to fix this liquid damaged 2020 Macbook pro and I noticed something weird.
When I push on/around the renesas 501cr0b IC, which appears to be a clock generator/ multiplier, If I apply lot of pressure, the device will reach 19.9 volts and seems to be trying to work.
I have thoroughly reflowed that area and completely removed that chip (there was some liquid stain in that area) but no help. I have just 5v 0a unless I apply the pressure.
Your help is GREATLY appreciated. Thanks! -
by dbuergiHi 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 ....1 Photo -
by fajfelekHello, First of all thanks you for reading this topic.
I need your help with identify missing parts on trackpad logic board (661-18430).
The liquid got into the orange area, but I found that the green area had some parts missing or burnt.
Please help me with identity parts from blue and red area .2 Photos -
by OruxHi all,
I’m new to the forum and could use a bit of help. My name is Tom and I have a problem 😅
I bought a MacBook Pro M1 and also got a second one for spare parts. The seller told me it had a small water spill. After opening it, I found four spots with corrosion on the board.
One of those spots has damaged components — I’m not sure if they’re capacitors or other SMD parts. I’ve already cleaned the whole board with isopropanol, which made the other areas look fine. But could those damaged caps be the reason why the MacBook won’t power on?...6 Photos -
by mitchwGot 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... - Loading...
