I have the same issue with a clean install on a raspberry pi 2. I have a hifiberry, a wifi dongle, a bluetooth dongle, a usb mouse and a usb keyboard attached.
I've tried to boot it with and without all that stuff attached. The green light flashes, and flashes shortly again. Then it won't flash again.
I created the sd card with windows via etcher, with linux using dd, and also tried to alter the boot partition (boot flag, primary). Screen stays black.
