See if you see a faint image on your screen. Place a flashlight on the backside of the lid shining though the Apple Logo when the system is running do you see your desktop and the icons on it?

If so, then your inverter and/or inverter cable needs replacing.

If not, do you have access to an external monitor? Try plugging it in and display on it?

i cant see anything. could it be the hard drive or ram since it makes the whining noise when i power it up

If the issue was RAM you would have gotten an error beep, if it was the HD you would have gotten a blinking question mark on the screen. Did you do the tests I outlined? Let us know what you discover.

Also try moving the screen back and forth to test the inverter cables and see if you get a screen picture or flicker.
