How to Repair DC Power Supply-English Subtitles

Desktop power supply is a very important and useful tool for laptop and mobile phone repairmen and is used for applying voltage and providing required voltages. Today a power supply is brought to us for repairing which its voltage doesn't decrease under 5 volt, which is a huge problem for those repairmen who need a voltage under 5 volt.
On the other hand, as most of us have one of them on our desk and work with them every single day, we thought repairing this most used tool might be interesting for you guys as well. So we decided to make this tutorial video.
So stay with us :)
And don’t forget to comment ;)
