Picked up my built to order Retina 5K this evening. Got home, plugged it in, heard the boot up chime and then... nothing. Just a black screen. The fan kicks in about a minute later (very loud), but the screen never comes on. I can pair the keyboard and hear keystrokes, but screen stays black. The only good thing I can say is yep, you truly can't see any pixels no matter how hard you look.
