Samsung USB Charger Failure and Repair

In this video I'm examining and repairing my faulty USB phone charger (5V 1A switching power supply). It failed after 2 years of seldom use. I've drawn a partial schematic in the video. Full reverse engineered schematic of this charger is here:

The moment when he said "SAMSOOUNG", my charger starts to repair itself

As soon as i heard his accent I went straight to the comments section 🤣🤣

Dude, I'm a technician and this is about the only size circuit I would attempt to troubleshoot. Trying to troubleshoot more advanced circuit systems like phased array radar systems and circuitry with analog and digital circuitry on the same board can be stressful and frustrating. This is a great starter circuit to learn how to troubleshoot. BTW, the guy doing this video would make a great electronics teacher.

Yeah the guy has an accent, but I bet 90% of those people making fun of him does not speak a foreign language, not even has the knowledge he does. So lets stop making fun and start learning ;) The content is VERY GOOD and he is speaking a very understandable english, I am not a native english speaker and I understand everything, in the end of the day that is what really matters. Come on, he could easily speak his native language and we would never understand it. Thanks for the good informative video.

like for Martian English

If you're paying attention to WHAT he's saying, you quickly stop noticing HOW he's saying it. Following his thought process is probably the best way of learning you will encounter anywhere. This guy is a pro.

The disadvantage is no screw nut

[@luistorh]

This man is a PRO. Only a PRO can smell the problem so quickly.... and hit the spot!

I wonder if confirmation bias ever plays into his thinking. Meaning if we tried to get an ok quality Chinese charger, but pack it into a Samsung, Apple, Sony etc charger, would he analyse the charger and believing it to be from a good brand, start saying how it's good and well designed. That is quite interesting to wonder.

Never heard this accent before. Best ive heard so far. Subscribed 😎

[@davo4174]

What do i know about electronic repairs? Nothing. But i watched the whole thing. I love your enthusiasm. Stay awesome!

[@omardude39]

That circuit diagram is the stuff of Engineers, this man knows this stuff. 😍

[@mehmetayparyangozalumni2606]

I was looking for someone who will explain how electronic things work , but like explain it with basic concepts and hands on learning , not theoretical stuff, your channel is perfect, thank you

[@ralorpa]

Before scrolling down to the comments, I also guessed lots of commenters would have fun with the voice. Its funny, but easy to hear anyway, because of good audio quality.

[@SouthSideChiTown]

I have no idea how you look at a circuit board and read it like a book. I've tried to learn this for a while, people who can do what you do amaze me. Great video!

[@trend7756]

Language is not a knowlege just a medium to express the knowledge. So unskilled stupid make fun of a skilled man. Thanks man for so detailed knowledge with patience and experience. Rarely i find such good vidio

[@sarabjitsidhu6928]

I love your way of speaking english.Good job.

[@dreamdecordesign7477]

One the best electronic tutorials on YT.

[@denisezaragosa4816]

You are such a brilliant guy.
