How to troubleshoot broken adapter?

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 !

Sadly, Apple does not provide schematics.

I should point out this is a risky venture! Between the possibility of hurting your self in the process in fixing it. You also really can’t reseal the case as good as it was, so it looses its EMI filtering and could be a shock risk or worse start a fire when used.

Best to just replace it with a new unit.
