Got a problem with my 17" Core 2 Duo... When connecting an external display, I can still view the extended screen. It works from time to time and usually tilting the screen fixes the screen back to normal but I can't do it anymore and its stuck like this: When applying pressure or twisting the bezel slightly, I can get the image to display but as soon as I let go, it goes back: What's wrong?? Loose connection somewhere? I've checked the display cable, but only the connection to the logic board. I didn't get to check inside the bezel to see if the cable connection there was solid. Thanks in advance!
