Why does my Samsung Galaxy Tab 3 10.1 not turn on after charging?

My GT-p5210 will not turn on even if its been on the charger for at least 24 hours.

I used my PS3 to charge it, my PC to charge it, and the original charger that was packaged with the GT-P5210, but for some reason, when I try to turn my tablet on, it will not turn on.

I wonder what could be the problem?
