Right SIDE usb.c port charges and transfers data without issue, two left side uSB c ports charge but do not receive or see data. Was liquid damaged, and repaired significantly and thought we were in the clear but appears this is the last issue that is rearing its head. I am trying to locate the RETIMER chip that communicates the DATA TX/RX but I cannot seem to find it on the schematic or maybe I am just so tired my eyes wore out lol. Any help would be great.

Hi all,
i got a Macbook A2442 which statrts normal but is not showing any picture. Using an external monitor works fine. After opening the Macbook i found a dried up line of liquid damage around CN979, RD503, and UP730. I cleaned up everything and also unsoldered the chips to clean the pads. There were no shorts before but i still don't have any picture. Sometimes you can see a glimpse of light in the middle of the display.
So before i change the whole display i want to make sure that it's not any issue with the logicboard. So any ideas what i can check next?... -
Hi All,
I'm working on a MacBook Pro A2442 (14", 2021) that's not powering on. On two out of three USB-C ports, I get 5V and the current briefly ramps up to around 0.210A before dropping to 0.036A. On the third port (JF600), I only get 0.0045A and it stays there.
Initially, I suspected a faulty CD3217 on that port, especially since I noticed signs of previous liquid damage near the JF600 USB connector. I replaced the CD3217 with an UF400 (from an A2442 donor board from the same location). According to the supplier, this should be a compatible version, but the behavior... -

Hi all
I have a Macbook Pro A2442 with the 820-02098 from a friend which has no picture on the display, however, the backlight works.
He was streaming a football match on a questionable site, then the site crashed, and the problem emerged.
Initially, he sent it to apple, who quoted him £1323.95 to replace the display, lid angle sensor and top case.
Obviously, he decided against this and gave it to me so that I could have a crack at it.
From initial diagnostics, I connected to an external monitor, I first tried with a HP 22W monitor, and I booted into the boot menu... -
Hi all,
I have a MacBook Pro A2442 with board 820-02098-A very highly oxydated (water) by an accident.
The customer just need to recover the data (no backups, heh), so we cleaned fully to make it power on.
Fortunately the Mac is still alive but it shows an exclamation mark in a circle (!) (Apple T2 fw issue?) with the text "support.apple.com/mac/restore" and doesn't go further.
We tried to interface with another Mac, but can't get in DFU. Very likely the keyboard is gone too because the water, so we're planning to buy a cheap compatible one just to....
