Why wont my tablet charge even though has the charge screen?

I have a Samsung Galaxy Tab A 10.1 Sm-T580. When it ran our of battery I forgot to charge it and when i tried charging it again it just showed the charging screen to when you first start charging it but it never charged. I have tried multiple cords in multiple places and nothing works. Sometimes if i keep it on charge that same screen starts flashing the charging icon brighter and darker. I have tried rebooting it and still nothing. I’ve moved the cable around gently to see if it was my charging port, it did the same thing over and over. I have done these things multiple times and still nothing. I don’t want to have to pay money and get it repaired unless i have to. If you’re having the same problem and you fixed it or you just have advice that i might be able to use that would be great. Any advice helps at this point!
