Mobile Adapter Repairing
I have put my mobile on charging I found that my mobile charging adapter is making some sparking noise this noise is from inside the adapter. So for diagnosing the problem I have opened the adapter. After opening I have started visual inspection first I have checked component side for physical damage and burnout marks but component side is ok.
Now turned back to soldering side of PCB here also there is no burnt mark so again I powered on the adapter to find out the location of sparking noise.
So I took my magnifier glass and checked this location and I found the culprit below (dry joint):
After resoldering the dry joint and powered On, the adapter was back to the life again. Sometimes in electronics repair there are tough problem to solve but there are also easy problem to solve just like the above case.
This means one has to try it out first before saying that you can’t repair the set. You need to open the set and don’t assume there is a big problem. If you want to be pro in power supply repair you can check out Jestine Yong’s power supply repair ebook HERE.

Good thing that you checked the sparking noise Yogesh. It could have lead to a fire or a burnt plastic housing!

vibhuti kumar,
First of all you just have to clear your funda about Testing components & SMPS troubleshooting guide by referring Jestine sir’s Ebooks. It is dangerous to troubleshoot the electronics device without prier knowledge.
