Hi,

My Sony BCG-34HRE battery charger has just died with a loud buzz and then a pop, so I decided to take it apart and see what exploded inside.

Getting inside required a bit of wrestling (damn you hidden screw!) and I took a few pics which I'm sharing here for posterity.













There are burnt marks behind the capacitor and also between the blue JECKSON package and the chip. What is that package?

I think it is (or was) a transformer.
