First of all hello I am new to these forums
secondly I just today had my monoprice nighthawk x9 repack/clone backlight stop working sometime over the night
I've had this keyboard some 6 months with 0 issues now suddenly this - wondering if anyone here would have any ideas for what it could be?
thanks
edit its just the backlight not working not the whole keyboard

If there is a common ground/power for all the LEDs, then something breaking the connection could cause all the backlit keys to not light up. Otherwise you might have just accidentally turned the backlighting off.
