LiitoKala Lii-500: Ремонт, який пішов не за планом...

In this video, I will show the process of disassembling and attempting to resuscitate the popular LiitoKala Lii-500 charger. It would seem that the reason was obvious - a specific part burned out, but the reality turned out to be more complicated. What you will see in the video: 1) Disassembling the case: how to carefully open the device and not damage the board. 2) Visual diagnostics: finding a burned-out component. 3) Repair process: Replacing the damaged part with a similar one from the donor board. 4) The moment of truth: the first turn-on after the “repair” and analysis of the result. Why did this happen? Unfortunately, replacing visible malfunctions does not always solve the problem. Often, the failure of one component entails the “brain” of the device (microcontroller) or hidden damage in other power circuits or the board itself. This video will be useful for those who have encountered similar symptoms in their LiitoKala, and for those who want to see the internal architecture of this charger before taking up the soldering iron.
