In the Yandex station mini, the contact of one leg of the power connector disappeared after a fall. In the photo, I showed the "master" which leg needs to be soldered at the junction with the board. He had soldered everything, but not what was needed. After not receiving a positive result, the "master", with some attacks, began to speak out that the cause of the malfunction was completely different and that I had broken everything myself.
I had to buy a soldering iron, spend 10 minutes of time and do everything myself.
In general, a negative experience.
One plus — I finally bought a soldering iron)
