Black screen but screen recognized by MacBook
Hi,
I have a Macbook Pro 17" (mi-2010) wich black screen and no backlight working.
I tryed to reset PRAM and SMC but it did nothing.
As i would like to know where could come from the problem i did several tests:
- When i plug an external screen, i have image on the second screen.
- In system preferences the macbook recognizes both displays (internal and external)
- In display configuration i can choose the option "optimised for built-in display"
- In system informations, i can see the two video cards, Intel HD graphics (internal) and Nvidia GeForce GT 330M (PCIe)
- When i unplugg the LVDS cable from macbook and i plugg it on a second one macbook, display is working properly
With all these tests and results, where is the problem and how to resolve it to have my display working again?
Thanks
Is this a good question?

i checked with the light behind the apple logo on top case and i can see the screen is working so, it's just a backlight problem but i still don't know how to fix it
