LED light acting weird

Recommended Posts



So I just created this account since today I just noticed that the "RED" LED light is not working on one of my keys(letter Z). I'm using a Corsair K70 Mk.2 Cherry MX switch.


So after noticing that I tried the following:


1. Restart my computer

2. Reset my keyboard with that ESC button method

3. Uninstalled and Re-installed my iCue - this includes deleting all corsair files with the %appdata% and %localappdata% method.

4. Tried a different computer.


All of the above didn't work.


Also, I did some tweaking on the color profile and noticed that if I change it to a Static color Yellow the letter Z is on Green, if I change it to Pink the letter Z is on Blue, if I change it on White the letter Z is on Sky Blue.


Has anybody encountered this on letter Z and has any fix for it?

Hi itsmeredg,


First, we sincerely apologize for any delay you experienced due to extraordinary holiday support/service request volume.


The next step here is going to be to try a firmware flash, followed by a warranty exchange of the keyboard potentially, if it's still within warranty. Go ahead and open a ticket with support, including a photograph of the LED problem, and the rear information panel of the keyboard, for the most expedited service.
