As the title says my screen is broken. When i turn it on the screen lights come on and I see the apple logo for about 3 secs then the lights shut off. I can still see the desktop but the screen lights do not come on and it stays black. I put it on sleep mode and woke it up to see if it would turn the lights on and it did turn the lights on for 3secs then turns back to black.

Can anyone help me out here?
