iPad 3 Wont Turn On. Help Please!

have a iPad 3 Mini. It cracked a little but it worked perfectly fine until I dropped it in the store. After about 15 minutes, it started to glitch. As the day progressed, the glitching got worse. Soon, a black screen came up with a bunch of line. I've tried holding the power and home button but it doesn't work. Nothing is showing up and I can't afford to buy a new iPad. Can anyone help?
