Tab 2 10.1 won't power on or charge.

I have a Samsung Galaxy Tab 2 10.1 that will not turn on and will not charge. Nothing happens when the power button is pressed or when the charging cord is plugged in. I have already tried the following:

Hold power button down.

Hold power button and vol- to perform hard reboot.

Hold power button and vol+ to perform hard reset.

Remove battery and hold power button down for 20 secs before replacing battery.

Replaced battery.

Any help would be appreciated.
