Hello everyone

I am a new Kindle owner...i've had it for 5 weeks and today was my first charge (aside from the out of the box charge). The indicator light is green and says it's charged but when I turn it on it does nothing. I have tried the holding the power for 30seconds and all that and nothing happens....I really want to scream fter pying $300 cnd for this hunk of wood...grrr
Any suggestions would be greatly appreciated
