Yup, green light to the right of the camera is on.
This is all that is showing when you launch Photobooth (see attachment)

This same problem happened to me. The iSight 'on light' turned on as soon as I started up my MacBook and had that weird green picture when I opened Photo Booth. Nothing could fix it... until I rebooted. Now it works fine and it's never happened again.

Have you tried rebooting? (Obvious, I know, but sometimes the best of us overlook such simple things :) )
 
Check whether it works in other apps before writing it off as dead. Also, unplug any USB and Firewire peripherals that may be taking up a lot of power. :)
 
It appears that my firewire is dead too.

My MB and my MBP are mirror images of each other. (drives are duplicates, same amount of memory) My iPod syncs just fine on my MBP, and only charges on my MB. Also, I can not get any of my other firewire drives to work on the MB.
 
The iSight on my 17" MBP is dead now too.

Transeau - did u have to yell at them to get an instant replacement? I can't wait another 2 weeks with out my MBP.
 
Whole computer or just iSight replaced

I just had my iSight die, after <1 week of ownership. Will the store replace my whole computer or just the isight?
 
10.4.7 / firmware update fixed it.

Weird - either the 10.4.7 or the 17" fan firmware update fixed my camera. Perhaps it does the PRAM reset mentioned above.
 
Solution for this on MacBook DC2

I just fixed this on my new Dual Core 2 MacBook. I decided to brave the annoying registration on this site to comment here... My camera light was on but the video window was either all black (in iChat) or all green (in Photobooth).

I was able to fix this by powercycling my MacBook...
  1. Shut down the machine
  2. Pull the power cord
  3. Remove the battery
  4. Hold down the Power Button for 5+ seconds

Hope this helps...
