Tablet suddenly died. Not receiving power.

I was Candy Crushin’ it and the tablet abruptly shut off and won’t turn back on. It doesn’t show a charging symbol, the LED doesn’t light, and it doesn’t vibrate when the charger is connected. The PC doesn’t recognize it, either. Seems completely dead, no life at all. I tried the reset (hold power, volume blah blah). Nothing.

I tested the battery, it’s still good (though I don’t know if it’s actually getting charged when I plug in the tablet.. It wouldn’t matter anyways, there is power in it). I can’t find any replacement moboards for this thing.. Any ideas?
