Today I plug in my G4 mdd to the power and find a components (L15) is broken. Is anyone able to identify it? When I connect to the power, this components is sparking. Thanks a lot.
Hi Kiizo, I am going to guess by the reference designator that L15 is an inductor or coil of some sort. It looks like it is connected to a really beefy trace on one side. They are often used for power conditioning.
