2 LCD working but no backlight.
I have a black 2008 macbook with a screen that displays images but without a backlight. The LCD will flash white when it is first turn on and then turn black. Using a flashlight, I can see the login screen on the LCD.
If I set the backlight to 0 and then to the lowest setting, the backlight will flash on and then turn back off. Sometimes, if I'm lucky I can raise the brightness to 4 before the backlight turns back off.
So far, I have:
- Replaced the inverter, no change
- Used compressed air to clean the inverter connections, no change
- Reseated the LCD connections, no change
- Reseated the connectors from the inverter to logic board, no change

One more thing - when the brightness is at its lowest setting, the backlight flickers before shutting off.
