zebranay , You can try charging it from computer if able for 4 hours to see if that may revive it, battery could be faulty. You can also try a reset, holding down the volume up and down and the power button until the phone light flashes red, then just hold the power button down for about 20 seconds or until power up.
Still no go may have to factory reset. Hold the volume up and the power buttons at the same time for a few seconds until the screen turns on. Scroll down to factory data reset and select with power button. Scroll down to yes and select with power button. Reset could take a little while. when screen appears select the reboot now with power button. Phone is now rest and hopefully operating normally.
