Is this a display data cable problem?
Hi there!
I have a problem with my MBP 2,2 GHz Quad-core with the AMD Radeon HD 6750M graphic card (early 2011). It is upgraded to OS X Lion (v. 10.7.5)
The problem is that the computer display stays black after startup. When i connect an external display the computer works like normal even though the screen on the computer is still black.
It happened a couple of times before, but a restart or two would make the problem go away. This time though the problem persists and I haven't been able to get the screen back on.
I have tried to reset SMC, reset NVRAM/PRAM, booting in safe mode and reinstalling OS X, but none of it worked.
I have tried running the extended mac hardware test, but this found nothing to be wrong.
I can't see an image when i shine a flashlight into the screen.
Under the hardware tab in the "System report" I can't seem to find the display and when i try the "Detect display" under systempreferences only the external display monitor is detected.
Also normally when I push down the display, the computer goes into sleep mode. Now nothing happens when i close down the lid and the computer just keeps on going like normal.
I haven't been able to find someone with the exact same symptoms on the internet.
As of what I can find on the internet of people having somewhat similar symptoms I am thinking it might be a display data cable problem, but since I have never opened up a laptop I would like to be sure before I open up my computer, if it is maybe still just a software problem.
Any help on what could be wrong and how to fix it is much appreciated! :)
Is this a good question?

Sometimes when i put down the lid, the computer does go into sleep mode, but it comes in periods of it working.
Another thing is that the camera is working just fine.
Any help is still much appreciated!
