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)
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.
