Why won't my Samsung SM-767VL charge?

When I plug in my phone to charge the circle with the lightning bolt showing that it's connected to the charger comes up on the screen but there is no battery level number or percentage showing. I have left it plugged in overnight, used different chargers and USB cords, tried different power sources and it still will not charge. If the phone is connecting to the charger why won't the battery take any charge? Noting happened to the phone it wasn't dropped or submerged in any liquid. It just started doing this all of a sudden.
