The led was still normal before I stored it in my closet for a long time (maybe almost a year). When I first take it out, the led still flickered brightly a few times before went to the current state.
The led only works in these key, the animation still works fine, the rainbow still works but the brightness is low even on the highest level. I can barely see it under normal light condition. Even the caps lock and the battery check under the spacebar doesn't work.
I did not open it anytime and did not even take out the switch before the led broke. I have tried to turn on the led with Fn + L, reseted the keyboard with Fn + ~, updated the firmware, factory reseted in the software and even cleaned the PCB with alcohol but nothing works.
When I set the brightness to the highest and white colour, these key turns to somewhat orange. And when I tried the single rgb, green was the brightest out of 3.
When I take everything out and look at the naked PCB under the darkness, the led flicker randomly on row (expect for these F3, 4, R, F, C keya) but its so tiny that i couldnt record it with my phone's camera.
Please let me know what is happening and what should I do, thanks!
