AC Question

My samsung galaxy j7 turned off by itself again for the third time. The other times I would just place it on the charger and all would be well. This time it just wont restart. When I plug it into the charger I get a black screen with the battery indicator flashing. When I take it off the charger I just get a black screen. Please help.
