I got a donor board with the same model and replaced the USB-C controllers in the same position. One port was still stuck at 5V, and the other port was cycling at 20V. Upon further investigation, I found no connection between pin 12 on UF300 and CF300. Basically, UF300 wasn't getting...

Are these cd32 serialized, or I can replace than individually?

Magsafe works fine and charges the Mac. All 3 USB-C ports are not working. The readings from all 4 CD3217 matches a working board.

Help Please. This Mac came in with no display. After replacing the screen, it displayed for a few minutes and then stopped again. EDP_AUXCH_C_N - OL Is there a way to fix this? Thanks

I replaced the chip from M1 Pro and the board is from M2 pro. Maintaining the same position.

Here is the thermal image if the charger is connected to the 20V cycling port.

I did replace from a M1 pro board and now one port is getting 20V and cycling and the other one is still stuck on 5V.

Do you think that CD3217 from M1820-02020 is compatible with the M2 820-02773 board?

I got it from an M2 Air, not the same board. Not the same position.

Hi, everyone. I need some help, please. This Macbook came in with no power. After inspection I found Liquid damage, corrosion near USB C controller (CF300) Both ports were initially stuck on 5V Replaced the USB C controller that is stuck on 5V, no difference. Replaced the second USB-C...

Hi, Good morning. Please, I need some help with this repair. It turns on only on battery, but it won't turn on when it runs out of battery. C520D blown/melted (PPDCIN_AON_CHGR_R). Removed. Diode mode readings to ISL appear correct compared with a working board. PPDCIN_AON = 5V...

Most likely it's a faulty LCD, a few times I found that numerous LCDs coming from China are faulty on arrival and cause all manner of issues; no boot, LCD test mode, etc. The LCDs for 14"/16" Apple Silicon models are pretty much all factory rejects, could be as basic as colour temperature, to...

I know this is a niche and its unlikely there is any answer, but a shot in the dark is worth it I replaced the LCD on a 2021 16" and customer complained about no FaceTime camera being detected and backlight issues - I replaced both ICs and backlight works fine now. I have tested the customers...

Thanks for your reply. After removing PMIC again and checking yes CPU is shorted, I forgot to mention that PP1V8_S2 was short to ground, I suspect due to corrosion on the JF202.... Removed the WiFi IC and the short is gone... So board is a write off :cry: Thanks for your time

Hi, I have this A2337 with liquid damage to the audio board and to the keyboard connector (PPBUS_AON_IPD_FLT - 3 pins completely gone on the FPC connector). I removed UC850 and replaced but still had abnormal reading on this line, so the IC wasn't the issue. PP1V8_AWAKE had a short due to...

R4805 was removed, and then I started to get 1.8V on pin 2. So I decided to replace U4850, and voila, 1.8V was achieved. Even then, the screen is not going to sleep. I replaced the right speaker and now everything is working fine. Thank you.

Hi, everybody. I need some, please. This Mac had liquid damaged on the Audio board and its cable. I've replaced both of than and Mac started to turn on. But it sometimes will have a backlight for a second when turned on and then goes off. PPVOUT_S0_LCDBKLT_F - 43.45V Even when the backlight is...

No DFU

I need help with this M1 Air, please. According to the customer, it was liquid damaged a year ago and has been off since. The main corrosion was on the U5200 and around. I've replaced R5230, U5200, U5215 and U5216. Was stuck on 5v 0.04A and after replacing all components it changed to 5V 0.190A...

RAA489900/Q5230/40 replaced and it works fine. Thanks
