I'm have a similar problem. I'm going to see I can reproduce the up down key work around.
Currently the blank screen manifest every other boot. Can either enter pass phase blind or Ctrl+alt+del, to force reset then screen is visible. If I knew how to generate all of those reports I would. Starts right after running software updater, even after fresh install.
