Samsung Galaxy Tab 2 Not booting, Not charging and not allowing to factory-reset

Issue: My Samsung Galaxy tab is not booting. And when I tried to "factory-reset" by pressing Volume Key + Power Button (I hold it for more that 1-minute), still, it does not showed me "factory-reset" screen.

• I kept Device for charging for nearly 3-Hours: No charging indicator is shown.


• It did not show up when connected to PC

I used this tablet for nearly 2-Years, seeing this issue for the first time.

VERY IMP: Device came in contact of water and since then it is not booting.

What options I try before taking device to Samsung service center??

Device: Samsung Galaxy Tab 2

Android OS Version: 4.1 Jelly Bean
