I have a RCA 7in tablet powered by android & the 5v charger that came with it broke so I bought a new one but when I plug it in it don't turn on. Shouldn't @ least a battery light come on letting u know it's charging. I get nothing There is another port that my android phone charger fits into will that charge my tablet.Granted it has been dead for ovr a month but shouldn't it turn on once its getting power. Plz help its brand new & has nothing wrong with it other than the charger breaking
