I need some help, please. The Mac has no signs of life. There is no liquid and no short anywhere on the board. All the coils measurements in diode mode are matching with the measurements on the FlexBV. I've tried to connect to another Mac, but it won't recognise it. Both USB-C ports are getting...

It's 0ohms

Just after posting, I ran another visual inspection on the logic board and discovered a missing resistor, R1540. I had replaced many of them before performing the U.S. cleaning, but I missed that one, and I believe it might have fallen into the U.C. machine. I replaced the missing resistors...

PLT_RESET_L - 3.33V I know it's a silly question, but should an SPI IC from another logic board work without changing the Serial Number? I swap the spi ic and same results. Removed J6100

Hi, everyone. I'm working on this board with liquid damage near U1900, R5614, C1210 and U5800. I've replaced a few resistors and caps in those areas; some weren't turning on before. So, after all the work I've done and doing a U.S cleaning. The board now comes on and the fan is spinning at...

Hi everyone, I need some quick advice, please. The MacBook came in with no power. Trackpad clicking and cycling. It has been opened before, presumably by the customer. The screen shield is missing for both the backlight and LVDS connector. There are no obvious shorts under the thermal camera...

R5222 faulty. Replaced and now the Mac is dead. :ROFLMAO: 5V 0.04amp

This are the readings.

Yes, it still shows the battery percentage after it stop to work. Just realise that after it stop charging just by restarting the mac it starts to recognize the charger and charge again. While it is charging. Q5265 – 12.23V Q5270 – SAVE_BAT_G - 5.60V – SAVE_BAT_S - 4.91V...

Yes, battery charges at the beginning after connecting the battery. If I disconnect the charger and plug it back, the battery stops to charge. Yes, both ports on both charger side are same.

Good morning, everyone. I received this MacBook for repair; it turns on but doesn't charge. The USB-C ports weren't working, and the AMP meter is cycling. After inspecting the logic board, I found that C5202 was blown, and PDCIN_AON_CHGR_R was shorted. I replaced the capacitor, and now it gets...

Hi everyone. CPU VCore present. Fan spins on then off then on and stays on full speed. No USB activity light turns on but not blinking. PPVCC_S0_CPU - 1.69V steady Very minor liquid on U1930 pin 6. U1930 replaced. The rest of the board is clean. Mac started to boot to the system and works...

TL866II Plus automatically changes the voltage. I forgot to take a picture of the error message. I will flash it again.

I'm using the TL866II Plus, but it doesn't have the profile for the IC AT25SF321, so I just remove the IC MX25U3235F from another logicboard that matches the schematics and flashed the firmware. Apple Cong. gives another error message and still not working. Should I be looking at why PP3V3_S5...

Do you have the firmware, please?

Just tried another good battery and SMC reset and same issue. This is the message it gets if leave Apple Configurator trying after 20 minutes.

I came to this post as I had exactly the same issue and symptoms. All EDP line is OK. The problem was the screen cable had a tiny crack on it just visible on the microscope.

This Mac was left in a humid and freezing environment overnight, and the next day it stopped working. There are no signs of corrosion or liquid damage. When I plug in the charger, the voltage goes to 20V, and the amps vary between 0.07a and 0.9a. After a few seconds, it drops to 0.03A, rises...

I've checked the FPC screen connector J8500 and on pin 36 - I2C_ALS_SCL is shorted 5.3ohm diode mode 0. The normal diode measurement on this pin is 0.463 according to another logic board. This line goes to a 1.1K resistor R5316 pin 1 PP1V8_G3S and pin 2 receives the signal (I2C_ALS_SCL) from T2...
