Title:

How to troubleshoot broken adapter?

Text:

Hi guys,

My Macbook adapter is not working. When I plug it on both ends, nothing happens, no light, nothing.

I opened it, and tested voltage with a voltmeter at the output of the circuit, at the start of the wire, and it's 0.

It thus seems that the problem is inside the circuit.

Here's a picture of it. Not sure whether it looks normal or not.

Any idea how I can troubleshoot it and potentially fix it ?

Thanks in advance !

Apple AC Adapter
