Well, my guess is the reason it doesn't turn on is that it is still out of power.
If no battery icon came on the screen when you charged it, IMO it probably didn't actually get charged.
If you used USB or a cig lighter port to charge, try a wall socket.
If you used the wall charger, double check that your charger was fully in the wall, the socket was working, nothing wrong with your cord.
You can test the charger at least by plugging in some other device by USB cord and seeing if it is getting power, but of course that doesn't help if it is your cord.
If you have another cord, try that one.
I haven't had any cords go bad yet, but I have had bad connections before when I thought I was charging and woke up to a dead tablet.
