How do I fix black screen?
Here are the symptoms:
-When you press the power button, the screen flashes white twice, then stays black. Otherwise, everything else starts up normally with the chime and hard drive sounds, etc.
-Shining a flashlight to the screen shows it still works (just no backlight?)
-I've reset the PRAM, no go
-I've replaced the inverter board but that didn't work
-It does work with an external monitor attached
I am currently running an extended Apple hardware test to see if it brings up anything specific.
Could something on the logic board be bad?
Bad CCFLs?

The hardware test did not find anything. Bummer.
