Hi everyone - first time poster on here looking to embark on my first repair! Thank you in advance for any help!
My Macbook only turns on when the charger is plugged in and only the trackpad and fans show signs of life. The display, caps lock light and touchbar do not turn on. There was previous liquid damage to the touchbar but after cleaning and drying the laptop was operational for a year without any issues. There doesn't seem to be any sign of liquid damage to the board, at present.
What I have done so far:

Hey guys, just troubleshooting a MacBook Pro A2289 with the 820-01987 logic board.
No fan spin, no booting, device not getting detected by the Apple Configurator.
Did a few basic things, the board gets to 20V USB supply according to my USB tester, F7000 fuse seem to be ok and not blown.
Board draws about 0.5A for about 10 seconds, after that it goes down to 0V. Found an n channel FET (Q4830) in the backlight supply(?) that could to be blown (pictures below), not quite sure about that, but t assume that should not be relevant, because I was testing the board...08-23-2024, 06:26 PM -
I have an A2251 820-01949 which had a failed TPS62180.
I was fortunate enough to find the video on "Exploding USB-C" https://youtu.be/CAGnMR1aVuE?si=O1oYvAyNMeAr4dv4 what was shared here on the topic.
I was wondering if there are any cross compatible models that have been discovered?
We have an apple ID locked A2179 Mac AIR it's CD3217B2 has different lithography and looks slightly gray but I'm assuming it's the same chip in principal, but I am also aware that for some inexplicable reason mac flashes these chips firmware depending on their location on the board.... -
Hi everyone. Just a reminder I am not a professional repair technician, fixing Apple electronics is my hobby.
Recently got my hands on MacBook Pro A2289 with interesting behavior. Pristine condition, no water damage, no visual issues whatsoever. It has no image, no CapsLock, no life except the fan is spinning. But it is able to boot into DFU and recognized by another MacBook. I tried to revive and restore the laptop, but the process ends when the MacBook usually should show an Apple logo with a progress bar. I assume the main power lines and T2 are working. It seems like the Intel... -
I have a A2251 2020 MBP with 4 Thunderbolt Ports. It has been working fine for some time and I woke up one morning to an unresponsive notebook
Opened it up and it looks like there are several ICs, which I think are capacitors burnt out.
How do I go about fixing this? I have repaired many iPhones in the past, but never a laptop motherboard. Do these capacitors just fail on a MBP? In which case, I assume I could just replace them and be good to go. Or does this indicate an upstream failure?...
