Will not boot at all, screen stays black
I just purchased a new DC-in board for my MacBook Pro because the old one was intermitantly charging.
I've installed and repaired a lot of parts on MacBooks in the past and have not had any issues.
This time i installed the new DC-in board and now it won't boot up at all. The hard drive makes noise as if its going to start up. But the backlight never lights up, then a few seconds later, it sounds like it shuts down and trys again, then the status light just says solid.
I've tried to reset PRAM, and everything possible. Tried hooking it up to an external monitor, it didn't work. Tried to tether the hard drive (I have another macbook pro 13"), it didn't work.
Everything i've read leads toward a bad logic board, but I'm stumped as to how it happened?
Thanks very much for any input! - Dan
Is this a good question?
