RCA tablet wont turn on

My RCA RCT6773W22 wont turn on anymore, after i tryed to root it woth king root. and dropped it a couple times but it was working perfectly. The first time this happened was when it turned off, i tried turning it back on but it stayed on the RCA logo but then i ended up turning it on and then it began to slow down. Then a day after, it turned off and when i tryed to turn it on it stayed on the RCA logo screen, every time i tried to reset it it would stay on that screen. i couldnt even put it in recovery mode, i plugged it in, and now the tablet just shows the charging batter ( still image , no animation for it ) its frozen, then turns off flashes and then does it all over again.
