Screen Flickers after login
So suddenly one day it started acting weird... It booted up, brought me to the logon, I signed in, and then the screen started flickering color and black. The weird thing is, I never saw the dock at the bottom (all I saw was blue and black) but it happens after I sign on. I just shut it down, and restarted, and now the screen doesn't even turn on. Is this the inverter cable or the logic board (I think it was stepped on)
Thanks!
Edit: The screen doesn't work at all now that it's unplugged and using battery. I can randomly get it to work plugged in.
Edit 2: I left it on for a while, and it went into standby mode and the backlight turned on. I tried to wake it from that, but then the backlight turned off. What the heck.

To help isolate the problem plug it in to an external monitor. See if moving the screen changes anything. Hold a flashlight at an angle to the scree and see if you can discern the desktop. Let us know your results. Thanks
I don't have a min-vga monitor or adapter (I can get one if needed) But I shined a light and I don't see anything. Sometimes I can actually see the login screen and logon successfully (backlight and all) but then it starts flickering...
Defective CCFL backlight may have the following symptoms: Screen flashes on red/pink and goes off. Picture stays on in red and slowly be come normal. Picture flickering with dim display. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of its life. Here's my previous post on this with links on repairing the CCFLs: http://www.ifixit.com/Answers/View/43895...
