I also have the same issue. Recently my MacBook began to die abnormally quickly, and now in the middle of use, the screen goes black as if i turned the brightness all the way down. I can still see activity if i shine a light on it, but i cannot see without it. I can presss F1 all the way, then slowly press F2 again, but it just goes black after about half a second. Very frustrating. Would I have the same issue with the inverter?
Answer to: Screen goes black but MacBook is still on!
