2 weeks ago when I plugged the power cord into my open but sleeping 2007 MacBook, it came alive for just a moment..and then the screen went black. Actually it wasn't exactly black - the computer was obviously running but the backlighting seemed to be out on the screen. I could still faintly see figures if I tilted it enough. A couple hours and a couple of restarts later, everything was back to normal.
A week ago, the same thing happened again. I took it to an Apple store, they told me it was either the inverter board or logic board..they replaced the inverter board and thought the problem was fixed. 12 hours later it was clear that it wasn't. Now I've noticed a pattern - if I shut my computer or let it fall asleep open, then when I open it/awake it, the screen lights up for a moment then the backlighting fails. If I restart it, it makes the turn-on noise but the screen stays black, or just lights up for a moment. But if I do it about 5 times, it will come on and everything is fine until I let it sleep again.
So my question is...is this definitely the logic board? And if so, how long will it take until complete failure? Thanks for any help!
