How we will diagnose the problem?

The best way to get an idea what could be wrong with newer type Macbook which have Type C dc jack. Firstly, we have to check with type C amp meter, it was showing only 5V output but the right output is 19V . That means there is something wrong with it.

Secondly, we have to check Type C power management IC U3200 with Multimeter which is located near the type C dc jack. You can see clearly in our YouTube video.

 

We have to put the multimeter in continuity mode. Then we will check the capacitors one which is on the ground and one is on the line. We are getting beep on two capacitors which is not right. Check where these capacitors were attached. The Type C Power ic U3200 is directly attached to the U2890. If PP3V3 line is shorted which is coming from U3200 that’s why we don’t get any power.
