Greetings, I have a 13.3" Macbook (Penryn); it has not been dropped or mistreated. The display is completely black, but running. (sound is functional) I can see the desktop if I shine a flashlight through the back of the Apple cutaway. If I close the lid to sleep it, and then quickly open it - the screen fully lights up for just a second. I tried opening it at different angles to no avail. Any thoughts? Inverter, backlight, etc? Thanks in advance!
The flashlight test indicates a failed inverter, the opening indicates a bad inverter cable. Look at this guide and use it to examine the cables first: MacBook Core 2 Duo LCD & Inverter A1181 (fast method) Replacement
