Just adding my comment/complaint. I love this keyboard, the feel, and the looks. But it has it's problems :/
The first one I got broke when I tried to replace the switches resulting in a non-functioning Left Control and keys doubling/tripling when I typed along with an LED on the bottom left that just didn't work with certain colors.
I just received my new one today and I had a whole section of LEDs not showing correctly along with a missing H keycap replaced with K making me have 2 K Keycaps.
NoxygenI had a visually identical problem as your led problem on my first one. I took mine apart to try and diagnose the problem, couldn't figure it out, reassembled it, and then the problem didn't exist anymore.
