Try plugging your phone into the original charger and then boot to recovery, from their try rebooting while still plugged in. If that doesn't work try this again but wipe just the caches and reboot while plugged in. I have had a screen go black before on other devices and plugging the original charger(car and most others didn't work) in and booting to recovery then rebooting would get it working again.
PS When you boot to recovery check your battery level.
