Why did the blue color on my RGB keyboard fade?

Question

Iron

I recently noticed that some colors are not displaying correctly. It turned out that the blue backlight on the left side of the keyboard became much paler. This is not the case with other colors. For example, if you put a completely pink color (see applications), then due to an imbalance in blue, the left side is more red than the specified one. It's sad that now I can't use the pink highlight. I would like to know what could be the problem and if anything can be done about it. Thank you in advance.

Answer 1

Most likely, the degradation of the blue LEDs, they began to lose emission and shine more weakly. It is treated by replacing them.

Answer 2

1. A problem with the controller (lowering PWM by the blue color of the RGB set diode)
2. Degradation of the blue LED (it’s quite real, the chemical composition there is not good for blue, red and green live forever).
3. Some of the blue LEDs are burned out and there is a skew.
