Bluetooth and iSight gone after removal glass cover?

Hi all, after removing the cracked glass cover from my (late 2008) unibody MacBook I found my Bluetooth and iSight no longer working. As far as I can see I didn't damage the iSight, nor the connected cables and boards. The green ON led still functions, the dim sensor on the other side also works and the iSight is still recognized as attached to USB (in the profiler). What could be the case here?

The second part of my problem is the fact that Bluetooth is no longer seen in the profiler and doesn't work anymore. Since that little card is in the display hinge, I don't see how I could have disturbed it. The Airport is still working by the way. On my other identical MacBook I once had the same problem with Bluetooth. I brought it in and you guess right, it worked OK when the tech checked it... and still does. Anyway I tried resetting PRam and SMC, without results. Any ideas anyone, please... Greetings from Holland.
