My iPhone 5 will not turn on

try again, plug your phone to the wall charger, then hold down the home/sleep button UNTIL you see the apple logo and then release, then wait until the phone boot backs up.

With the phone plugged to the wall charger also?

Take it to an Apple Store Genius Bar.

Should be under warranty.
