How to repair the LED lamp?

Alena asks:
Good afternoon! The LED lamp stopped turning on. I took it apart and I can’t understand what needs to be replaced there. I beg you for advice, as our electrician said that it was not in his competence (((
Burned out LED lamp
The answer to the question:
Hello! No matter how funny it may sound, but you need to replace the lamp. In the photo that you sent, this is a board with LEDs, in truth, 1 LED burned out there, but you can not replace it. To do this, you need to determine which LED burned out, find the same and solder instead of the burned out one. On the burned-out LED, most likely, a dark or black dot appeared.

You are unlikely to find the same board with LEDs.

Less likely, but still there is - the driver (power source) has burned out, most likely, this wire goes to the connector from it. But you yourself are unlikely to determine what exactly failed.
