So I've had mine (with LEDs pre-installed) in for a bit now, and I gotta say I'm loving it so far. It's unfortunate though that I come home to one of my LEDs flickering (the number 9 key to be specific). Is this common among boards that come pre-installed with LEDs? Has anyone else who got one with LEDs had any problems? What are steps I can take to address said issue? Any help would be greatly appreciated!
