This problem has been recognized by Samsung, it's a factory thing, all You need to do, is open your tab, remove the battery cable for about 10 mins and plug it back again, unplug the screen from the motherboard, and charge it for about, two hours, then plug back the screen connector, and turn it on, if you see it works, turn off the tablet again, and plug in the power cord again, you'll see the charging animation starts, leave it charging for the time you think it's necessary to reach 100%, unplug the cable and turn it on, your tablet is alive, the only problem I've found about this, is that you'll need to turn the tablet completely off whenever you want to charge it, and finally this, VERY IMPORTANT! When your tablet is below 15 or 10% battery, charge it, because if you let the battery die, probably you'll have to do all the steps again.
