Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
Is there any reaction when the phone is connected to the charger? Have you tried with another charger to see if this can help?
I suggest that you disconnect the phone from any kind of power source, hold the ON/OFF + volume up(+) button for 10 seconds. Without trying to power on the phone, connect it to the charger via wall socket and let it charge for 2-3 hourse before you try to power it on.
