Why did the LED spotlight start to malfunction?

Evgeny Tsygankov asks:
There was an LED spotlight on the automation, no one touched it, it worked well, but then it began to work incorrectly, on the automation it lights up, and it does not light up exactly as it should.
The answer to the question:
A very collective image "not quite as it should." What does it mean? It began to shine not so brightly? If yes, then this is normal for LEDs. They degrade, burn out areas of the matrices and so on.

If everything is fine with the wiring, good contact is everywhere and there are no commonplace, such as dirty glass, then the easiest way is to replace the spotlight. If you understand in electronics, you can replace the LED matrix or driver after diagnostics, but in most cases this is not cost-effective.
