HELP!!!! Built-in Isight not working!

Hi Guys,

I'm new on this site so hello to each and everyone....
Ok on to my problem.... I have a Macbook Pro Intel Core 2 Duo and I was using skype fine when all of a sudden the camera stopped working. I cant see it in the System Profiler, it wont work in Photo Booth, Ichat or Skype what can I do???? Have tried pressing cmd+alt+P+R on boot up also shift on boot-up but nothing..
I would greatly appreciate any help..

Many thanks in advance

Phil..

The iSight may have failed. If you can't see it in the System Profiler or if it won't activate in Photo Booth or Skype that's an indication that it may have quit working. Try running the Apple Hardware Test to see what it says. See this LINK.

Also give resetting the SMC a go.
