Question : Problem: Built in isight not working on Macbook Pro

Built in iSight no longer works on my MacBook Pro.

I have done a PRAM reset, PMU reset, run Onyx and nothing fixes it.
System Profiler USB section doesn't show it.

Any ideas? Thanks.

EZ Jim has a fairly comprehensive view at the bottom.
removing and replacing the battery seems to affect some of the posts, you do that when resetting the smc anyway.

If nothing works or unless you get a better expert, I guess a trip to a dealer might be needed, I'm sorry if I haven't helped.
