Dropped my iphone 4, screen went blank, and now it won't turn back on

I dropped it on its top edge from about a foot off the ground and the screen didn't shut off, it just went blank. I than tried to take snapshots and see if the sound was working but nothing happened. Finally I tried holding the home and lock button at the same time and finally the screen shut off. Now when I try to turn my phone on, it won't start up. I even plugged it into the computer. I'm starting believe that I have the worst luck in the world, but please help if you can D: I'm desperate.

Take it to an electronics repair center. It's not cheap but it could be worth it.

you can look up non-apple repair centers online…

or maybe have the screen replaced.
