Struck by this same issue today when applying the April 2018 BIOS firmware patch. My keyboard cycles through the colors but nothing appears on the screen. I've posted a youtube on this as well and reported Razer to several online consumer forums. Of course, my system is out of warranty and Razer wants me to RMA/pay for the services to fix a problem caused by their updater. This is a racket for such an expensive piece of hardware and will officially be the first and last Razer my family will ever purchase. The worst part is that before terminating my call with technical support, the representative snickered when I told him that I plan to report them to the BBB. Good luck to anyone who owns this unit.
