MacBook 15 early 2011 Magsafe port replacement / Blackscreen
My charger blew up the magsafeport (short circuit).
I ordered a new one and installed it.
Everything works fine but the screen has problems. The backlight works ok but there is no image.
I am using an external monitor and i can see :
Color LCD:
Display Type: LCD
Resolution: 1680 x 1050
Pixel Depth: 32-Bit Color (ARGB8888)
Mirror: On
Mirror Status: Hardware Mirror
Online: Yes
Built-In: Yes
Maestro243DL:
Resolution: 1920 x 1080 @ 50 Hz
Pixel Depth: 32-Bit Color (ARGB8888)
Display Serial Number: D280C0064021
Main Display: Yes
Mirror: On
Mirror Status: Master Mirror
Online: Yes
Television: Yes
but the screens stays black.
I tried all possible resets ( Pram / Nvram , SMC )
I checked the cables inside and everything seems fine. Sleep mode activates and deactivates the lcd backlight normally.
I searched the net for every piece of info about this and the only conclusion is that something in the logic board was damaged along with the magsafe port.
Thanks!
