Iphone 4 help! Black screen?

I restored my iphone from itunes and now it just gives me a little brighter screen but its black. You can't see anything you can just see its a lil lighter than the off button what should i do? Thanks for your help! But i tired to hold down the home button and the power button but it doesn't shut down or give me the apple logo thing. What should i do?

I think you need to restore your phone again. Try it.
