Try plugging into wall and or computer with factory cord. It might turn it on and then you can proceed to try ap fastboot. Your recovery is probably corrupt.

When you say factory charger are you talking about the one that came with your phone? That's not what hes suggesting. He is suggesting you use either option from here . This will try to boot the phone running straight off USB power instead of going through the battery.
