Thanks to reply. Should I use same location CD3217 on A2485?

Hello, This is CD3217(Left UG400) Problem. I have no A2442 doner board. So I wolud like use other A2338, A2337, A2485 boards. As I know it should be same board and same location? or Can I use other CD3217 A2337,A2338,A2485 etc.. And one more question. When I testing hot spot. CD3217 and also...

I tried revive, restore with IPSW but it does not work. "AMRestoreErrorDomain Failed to receive message from device, might be connection problem with USB host. (Communication error, possibly USB disconnection)) [AMRestoreErrorDomain – 0x9 (9)" It's reboot during installation after...

It boots normally, but after about 30 seconds, it turns off and reboots repeatedly.

Hello, this is the 820-02098 (A2442). There was no water damage. 20V boots normally, but it keeps turning off and on. There seems to be no short value when testing diode mode. - PPBUS_AON 11.98V (when turned off) 12.27V (when turned off) - PPVIN_P3V8AON 11.98V - PP0V9_ATCRTMR2_SVR 0V -...

Hello I got A2141(820-01700) stuck at 5V, There is a fever in the PMU. PP3V3_G3H circuit is short. If I replace the PMU on the other donor board, will the PMU work normally?

I'm sorry, but I don't know how to measure resistance. black and red probes on pin 1 and 2 of RP830 in multimeter ohm mode and check if ohm 0 comes out?

Hello This macbook does not work display backlight after water damage. There was water damage on UP800 PP5V_S2_MAIN was short. When I tested power supply, UP800 had a fever and I replaced UP800,CP818,CP817. PP5V_S2_MAIN has no more shorts. Everything seems normal, but the backlight still...

I don't know why, but the symptoms suddenly disappeared and everything is working fine now. Anyway, the problem was CD3217.

Yes, all ports have the same symptoms. MagSafe 3 works fine also charges well. Around CD3217 diode value looks fine except above values.

Thanks to reply I get it from same donor board and same location. Even before replacing the Ug400 It was same problem.

Hello, this board has water damage. It goes up to 20V, then turns off and on again. I keep repeating. It boots normally when turned on with the battery but won't charge. There was water damage in the UG400 (CD3217), and I replaced the UG400 and peripheral capacitors. The symptoms are still the...

Hello, this is a basic question. When checking the capacitor in diode mode and conduction mode with multimeter. Diode mode measurements come in V and DC, Is that means voltage value? Is the measurement in conduction mode a resistance value?

In the case of the board view on a black background, the C7713 (0.163) voltage is marked, but the board view I purchased on a white background does not have a voltage. Also, how can I get the voltage from the circuit diagram? Sorry for the basic questions.

Hello I just started studying logic board repair. I have all the equipment and logic boards. I've been running a MacBook repair shop for 10 years, so I'm aware of MacBook hardware. I saw Rossmann Repair Training Guide and REWA MacBook Motherboard Repair Course ($299). But I still don't solve...
