Isight and connectivity-cant get it to work

Question

I cant get my isight to give me any signal. i have checked my isight camera on my laptop and it works. i have gone to imoveHD and in camera mode there is not triangle that comes up to select isight. i have gone to ichat av and under preferences and to the video button, and it tells me there is no camera connected. i plug it in, the green light starts on the isight and then goes off. comes back on when i use isight with my laptop. i searched my computer for isight stuff and the only thing that comes up is an isight audio plug in. i tried to install the isight 1.0.3 firmware upgrade and it says it is not able to install it on computers running 10.4. i tried to download the 1.0.2 but it keeps going to the 1.0.3. i tried to do this on my own but have failed miserably.
any help would be appreciated.

Hello john,
All required iSight firmware updates are applied automatically by the Tiger install. You do not need to worry about doing that again now.
Neither should you be concerned about the green light blinking on and off. It is normal for iSight's green light to turn off after you connect it. The green light should come back on when iSight is in use, but that will likely happen once you get iSight working.
Please post back the answers to the following questions if you do not get going with these suggestions.
(0) I am confused by your first two sentences. Do you mean that the same iSight that works on your "laptop" will not work on your iMac?
If so, and if your "laptop" is a Mac, then your iMac needs work. Some additional info will be needed if the following do not get you going.
Your post sounds as though you may have tried using the hints in the How To Ensure Your iSight Is Functional FAQ.
](1) Is that true for BOTH computers?
](2) If so, are the results the same for both of your Macs?
](3) When you have your iSight connected to your iMac, does your iMac's System Profiler recognize your iSight as a Firewire device?
(4) Have you repaired permissions since you updated to 10.4.2?
(5) Do you regularly perform Mac OS X maintenance?
(6) When you upgraded to 10.4.2, did you just click "install" when notified that there was an OS X update available?
(7) Have you repaired permissions since you updated to 10.4.2?
If the answer to (7) is "yes," I suggest you apply the new 10.4.3 Combo Update using the method suggested in How I Update My Mac OS X. If the answer is "no," repair permissions now and see whether that gets your iSight working.
My best suggestions to get your iSight working with iChat AV are in Help for iChat AV 3 Problems.
If you are new to iSight or iChat AV, you might also find some useful ideas in Using iSight with iChat AV.
If you need to post back it will also be helpful if you will tell us:
(8) Processor type and speed on all Macs to which you refer in your post.
(9) Whether you have Possible hardware or software conflicts with iSight.
