me too have some apple psu that is not working, but working on a 220v line is a bit dangerous :S

Hi
I don't have the schematics but I would like to share some photos and information about repairing a 85W magsafe died due to power surge...

My Mac Book Pro charged exploded with a loud sound and smoke. I decided to open it and fix it. I read online a wonderful method to open these kind of adapters. After a visual inspection i found out that the black soot have covered all the damaged area so I cleared it with damp cloth and luckily i was able to read the values printed on the dead components.

These components are connected like this

Fuse in Plug -> Varistor->Sidactor(Thyristor)->Fuse->(unkown circuit)

BS1362 3A ATLAS Fuse ->TVR 14271 -> p1300ec ->T3.15A 250V square fuse

With the help of my elder brother i was able to get these item from local market i changed these items and now my charger is working fine.

Replaced with

BS1362 3A Bussman Fuse -> ZNR14K271U -> p1300ec -> T3.15A 250V square fuse

This sidactor (p1300ec) have a capacitance of 0.054nF. (test tip)
