i have problem when i am assembling my kmac86. once i press caps lock, it works but the LED is not working. it doesn't work in both position and i am sure the positive and negative side is correct. Instead, the LED at Left Ctrl works. So right now when i press caps lock, it functions and ctrl will light up. WTF....
BTW i have great confidence in my soldering skill since i have worked on switching 104 LEDs for others for a long time.
