I've been experiencing some problems with the backlight of my AW510K keyboard. I have the latest Command Center and Peripheral software installed. Whenever I select all keys in my keyboard and change to a particular color, I see that 2-3 keys are not changing to the right color. For instance, if I choose red, then the entire keyboard is red, except for these 2-3 keys that show up in purple or when I change the entire keyboard to green, these 2-3 keys are blue. I have tried uninstalling the Command Center and Peripheral driver software, restarting my PC, unplugging and replugging the keyboard into different USB ports and different systems. I feel that this could be a hardware issue.
