No rgb working - blackwidow v3 hyperspeed phantom edition

here is the story, I haven't done anything wrong like spilling water on it or stuff like that but the "ALL" rgb has died on the keyboard the thing is if I wait about an hour if my keyboard is unplugged but on (it goes power saving mode) all the rgb will flash white for less then a second when the keyboard wakes up (I touch a key) so I don't know if its a problem with a controller somewhere or if one key has died and that made the whole thing go haywire because all the keys and functions of eveything work fine.
I have tried everything from hard resting it to letting it fully die and starting it to spamming fn and u to turn brightness up and using a different computer from being wireless and plugged in, if anyone has an idea or if my thing is just dead an answer would be nice
