Photo recovery from a MotoX phone with black screen

I have a MotoX (1st Gen) phone. A few days back my display went black and I am not able to see anything once the phone boots. The notifications are getting displayed on the locked screen, but when I am trying to unlock, the screen is getting black again. The voice command is responding sometimes, but that's about it. I have cleared the cache partition, but that did not help either. Please tell me some way to recover the photos/videos in my mobile.
