    Re-installing Snow Leopard and re-installing software updates didn't work either.

    The iSight camera still works using Skype/Windows XP/Parallels.


    Your most recently posted system info now shows that you are using Mac OS X (10.6.2). Because you also posted that you updated, I expect 10.6.2 is a posting error. If it is not, apply the 10.6.4 Combo using the method suggested previously.

    Based on the results of all you have tried, iSight problems remaining at this time seem likely to be related to a conflict with your third-party software. Check to be sure both Parallels and XP are updated to the latest versions compatible with your system. If your problem remains when you are certain you are using the latest compatible Mac OS X (10.6.4), Parallels, and XP, I have these two remaining suggestions:

    (1) Backup all important files and take your Mac for service by an Apple-Authorized Service Provider. The Service Technicians have test equipment and technical data that will likely allow them to diagnose and repair your problem faster than my second suggestion.

    (2) Alternatively, backup all important files and then zero your startup drive. Reinstall and update Mac OS X only. You iSight should almost certainly work with your OS X apps after a clean install and before you restore any other files including XP and Parallels.

    If iSight works now, you can restore your data files, but *do not add any non-Apple apps, plugins, etc., until you are confident that your iSight is working properly*.

    If you still need to use Windows® after you get iSight working in OS X, reinstall Parallels but not Windows®. To be sure that your Parallels installation is not the source of your problem, test OS X apps with iSight again after installing Parallels but before installing Windows®.

    If iSight still works properly at this point, you can install XP. Test whether iSight still works with OS X apps after reinstalling XP. Next, test iSight with XP and finish with another test using OS X apps.

    If iSight continues to work, you can add any necessary add-ons or plug-ins. However, make any additions one item at a time, testing thoroughly after each addition. This add-test-add tactic assures that you can identify which addition might prove to be the cause of your problem.

    If iSight fails anywhere in this item (2) procedure, I can only recommend a visit to the AASP.

    Yes - my signature was wrong (I don't use this site very often). I have been running 10.6.4 since it was releeased.

    It could very well be some 3rd party software however I only installed Skype on Windows XP and Skype on OSX after I came across the problem with iSight to check i it was just a problem with the Apple apps or if it could be hardware, in which case the camera wouldn't work on OSX or XP.

    I realise doing a clean install is probably the ultimate solution but it is such a PITA that it seems a pity there isn't some other debug information to diagnose the problem. I have a MacBook Pro and iSight works perfectly on this so could compare a working and non-working system, but I don't know what to look for.

    The other thing I will try is borrow an external webcam and see if that works, and if it does, if moving between the external webcam back to iSight may force iSight to work properly.

    After that, I may wait until 10.6.5 is released to see if that fixes the problem, before trying the clean install.

    every video app gives that message about timing out whilst waiting for pbs...

    Is that process running in Activity Monitor? (shouldn't be)
    what happens if you run it manually, opening /System/Library/CoreServices/pbs ?
    I get
    $ /System/Library/CoreServices/pbs ; exit;
    No languages specified - assuming English.


    Just a thought...

    Hello, redhanded

    You have my best suggestions. 

    ... I have a MacBook Pro and ... I will try is borrow an external webcam ...


    You have some creative ideas for more troubleshooting options using your MBP and another webcam.

    If you cannot get sorted with help from others who post here, an AASP will be able to get your iMac working properly.
