First thing you need to do is find out if the phone charging. You can buy a usb amp meter (very cheap) and check if the phone is drawing any amps. Anything between 0.2 to 1amp is good and means  the phone is charging as it should. Your problem could be a display issue where the phone is working but not able to display an image or backlight to the screen. This is caused by either a short on the 5.7v rail or the display chesnut ic. You can see a video here that talks about how the 5.7v line works.
