1 Power on black screen. Runs cooler no sound start.
Macbook Pro 13 a1278 MB 820-2936-B.
Good afternoon. I'll be glad for any help. I have a MacBook Pro a1278 problem is that he is charged is included but does not emit any sounds not just a black screen and cooler starts to work very quickly. I turn off the computer memory rented conclude disconnect the hard drive dvd just not any squeaks nothing more :(
I do not know what the problem is. Computer used almost did not work only on weekends is not any damage. BGA heated thought the same thing. When you turn on a light bulb lit on the front poneli loading drive and silence all black screen.
Perhaps there is no power to the cpu. I can not find a scheme that would check the power .

Are you fixing the logic board here? As some of your points imply that. Can you give us some details what happened when the system stopped working before you took the logic board out. And can you tell us what you have done already.
