I had a unit come in yesterday. A2179. No power, not charging. 5V on both USB-C ports, U3200 was getting hot, while U3100 apeared normal. No liquid damage at all. I went ahead and replaced U3200. Still not powering on. 5V and voltage fluctuates and then settles at 0.192A on both ports. I...

I removed U7000 and C7050 voltage is 0v

SMC_USBC_INT_L = 3.401 P_IN = 5.194 AUX_DET = 1.290 SMC_RST_IN = 0V VDDA = 5.109 VDDP = 5.109 SMC_RST_R_L = 3.410 AUX_OK = 3.410 A_MON = 0V B_MON = 0V Attempting to connect a known good battery causes there to be no activity on charger. Tried two different batteries. As soon as battery is...

PPBUS_G3H diode reading is 0.438 Replaced the redriver chip anyway and no change.

No heat on redriver chip. PPBUS_G3H is 0.061V PP3V3_G3H is 3.402V

Hi there. This Macbook came in with no power. Stuck at 5V on both USB-C ports and hovers between 40mA and 26mA, never gets to 20V. . I believe it was a cheap power cable that caused this. Board is 820-00840. PPBUS_G3H is missing, all other necessary voltages appear to be present. There are no...

The unit just decided to start charging, ill report back if issue persists

I have a L-2011 820-2936 here that came in with a no charge issue. Battery tested faulty. Board will not power up fully on charger with battery connected (fan spin for 3 seconds then power off) Zero signs of liquid or corrosion on board. Will boot with battery AND charger connected, but will not...

I came in this morning and attempted to power up again. It fired right up and is now working normally. Lets just hope it stays that way

Hello. I have a 2015 15" MacBook Pro here that all of a sudden fails to chime or display an image following removal of the logic board and thermal re-grease. Its an 820-00426 Board. I tested this unit fully before disassembly and it ran perfect and passed all diagnostic tests. There is ZERO...

Is there no help out there?

Correction, It goes from 5V to 19.4V and stays there

Thank you. Unfortunately today the board decided it wont power up at all. It goes from 5V to 20V - 0A and just stays there. SMC_RESET_L is 3.4V. This is with the board out of the unit, bare. I have tried all four ports with same result. No shorts on SMBUS_SMC_5_G3H_SDA or SMBUS_SMC_5_G3H_SCL...

I went ahead and replaced the SMC, no change.

Bad SMC?

Hello. SMC_ONOFF_L is 3.4V with and without touch ID connected. With connected, and pushing power button, SMC-ONOFF_L drops to 0.04V. This seems normal, correct? Machine still does not power off.

Hi there. I have a liquid damaged unit here. 2016 13"MBP 1706 (820-00923) It originally had a no power issue due to issues one of the CD3215's. I resolved that issue by cleaning up the areas that were corroded and then tested all capacitors and resistors. The board was now able to power up but...

Machine stays on with J9600 disconnected. Also tried booting into USB with J9600 connected and then unmounting SSD right after desktop is shown. Machine stays on. It shuts off after a few mins when attempting to read data using R-Studio.

I am attempting to recover data off of an A1707 2016 Touchbar - 820-00281. It refuses to boot either one of the two accounts, with filevault enabled, but will boot into Guest mode. I have also made several attempts in connecting the drive via Target disk mode. The machine successfully enters...

So the board is now toast?
