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!

You have to check the damage near to Display Jack on the Logic Board . Post the Snaps of Area near by jack of Display . if everything looks fine . Try to reinstall the logic board. Check it other wise have to check with new display panel. If display comes with new display panel then fine. After this we have to replace the logic board or repair it.

Where is located the display panel (is it near the magsafe port with the cable that goes to the screen(Right) or is it in other side (left)?, anyway i already checked everything in both sides and all seems to be ok. I reinstalled the board and problem persists.

What i would like to know is, when there is a Short circuit that burns de magsafe port is it possible that other components might burn?

Thanks
