JABRA 510 overheating and had no sound

One day, while connecting to my macbook adapter (the macbook connected to the adapter too), jabra just went pop.

When I click on "On", the lights will lit up then disappear. Then the middle portion becomes really hot.

I wanted to get it fixed because it is not cheap. However, jabra said 2 years warranty only and no servicing centre after that. So I have to figure it up myself.

What parts do you think is affected? I wonder if I should try fixing it myself.
