Indeed Yogesh, a good schematic makes an already half finished repair! Like taking snapshots of any internal circuit or board in any device is by saving time on any future repairs. Especially when parts afterwards are blown or burned, and no longer can be read or catagorized.

Who ever would have thought that connecting a HV tester onto the primary inputs of a small smps adapter would be that simple but never before used method? Not me dear Parasuraman!, lol.
It is probably why we learn never to do such a thing. But when we do, it turns out that it really works as a new and safe test method in almost all cases!
I guess we sometimes just have to think 'out of the box' to come up with something new.

Very informative and thorough probing all the in and out of these small devices, that too with your unique methods! We are all lucky to have such a professor who teaches us something or other in almost every article!

I think so too Lynn but according to the dislikes I got apparently not everyone agrees?
