Why does my iSight camera periodically stop working, requiring PMU reset?

Just wondering why this happens?
Using a Feb 2011 Macbook Pro with OSX Lion 10.7.4
It seems that every time i use my built-in iSight camera, then the next time i go to use it, it can not be found. This requires that I reset the PMU, which is kind of annoying. Then it works for a few weeks and the cycle of iSight begins again.
Why does this happen? It seems pretty trivial to consistently recognize a camera which is wired into my computer. Is there something I could do to prevent this from happening again? I have tried turning it on and off again.
And currently, this article is linking to the reset instructions for Intel iMac instead of the Macbook Pro page...

One of the following will fix it.
(0) If you need help with the following suggestions,
      you might rather contact your local retailer or
      Apple Authorized Service Provider (AASP) for help.
      They can help you or determine whether your Mac
      needs hardware service or only a software problem.
(1) Close all open apps that use the camera and then
     try again with only one app running at a time.
     If the problem continues, delete any Log-In items and
     Dashboard Widgets that might be using your camera.
(2) Try Apple's http://support.apple.com/kb/HT2090
     Be sure to use the correct SMC/PMU reset procedure
     for your particular MBP model: model with a battery
     you should not remove on your own
     If these suggestions do not help, yours may be a
     hardware problem that will require a professional fix.
    Unless you have a current backup, make one now.
    Then use the final "Troubleshooting" suggestion:
"... contact Apple or an Apple-Authorized Service Provider for service."
(3) If you want to try one more thing on your own first,
     you can use Disk Utility to repair permissions. Then
     download and apply the latest Lion Combo Update:
      http://support.apple.com/kb/DL1524
    Repair permissions again immediately following the
    system restart that completes the Combo update.
Properly applying the Combo version of updates can sometimes correct software problems, but, if your trouble is caused by a hardware problem, there are no user serviceable parts of iSight. See your AASP for hardware problems.

The article actually has THREE links to TWO different SMU/PMU reset instructions:
• iMac G5 (iSight),
• Intel-based iMacs;
• MacBook and MacBook Pro
You should use the last one ( http://support.apple.com/kb/HT3964 ) Yes, it is the same article as for iNtel-based iMacs, but it is the correct one for you.
The important thing is to page down to the section entitled "Resetting the System Management Controller (SMC)".   Then click the reveal triangle ( ▶ ) to see and carefully follow the specific reset instructions for "Resetting the SMC on portables with a battery you should not remove on your own". This is the proper reset process for your "Feb 2011 Macbook Pro".

MY COMPUTER (ISIGHT) CAMERA HAS STOPPED WORKING.... HOW DO I TURN IT BACK ON?

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
See:
* [[Troubleshooting extensions and themes]]
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Built In iSight camera has stopped working on 27 inch iMac and 27 inch LED.

The camera's on my 27 inch i7 imac and 27 inch cinema display all of a sudden just stopped working. I checked in the system profiler, and both show that
they are connected. When I try video chat in iChat the green light comes on and connects like it's a one way video chat... when I try and switch to the display monitor's iSight the green light switches to the other monitor, but the camera is still black... I tried this with Facetime, Skype, and Photobooth, all nothing... Any insght into this would be great. I'm thinking that it could be an internal hardware problem with the machine... Logic or Motherboard....
Any info would be helpful
thank you

Built-in iSight cameras
These steps are for iSight cameras that are built into a computer, such as the iMac G5 (iSight) or later, the MacBook, or MacBook Pro.
See if the issue is application-specific.
Try another application (iSight works with applications like iChat, PhotoBooth, and iMovie HD 6) to see if the iSight camera exhibits the same behavior in all applications. If it only happens in one application, try reinstalling that application.
See if the issue is user-specific.
Test your iSight camera in another user account. If the issue only occurs in one user, the issue would be isolated to user settings.
Find out if the computer recognizes the iSight
Check System Profiler (in the Utilities folder, inside the Applications folder). Under the USB header, check to see if the iSight camera is detected.
Reset SMC or PMU
Reset your computer's SMC or PMU, and then check System Profiler again. (SMC reset instructions for iMac G5 (iSight), Intel-based iMacs; PMU reset instructions for MacBook and MacBook Pro.)

Built-in iSight cam randomly stopped working. All I get is a green screen!

I used it just yesterday with both Photobooth and iChat with no problems what so ever. Now all it shows is a green screen! Anybody know what the problem may be and how to fix it??? Thanks!
-Jonathon

Welcome to Discussions, -Jonathon
Here are the solutions that help most users who encounter green-screen problems. None are complicated, but the only way to find which one will work for you is to try them one-by-one until you find the one that fixes your Mac.
(1) Check your System Preferences as explained in this kbase article about Built-in iSight camera produces blue or green pictures.
(2) If your System Preferences are set correctly, try every suggestion re: Built-in iSight in the "How to Troubleshoot iSight" article.
Be sure to include the checks for whether the problem is "application-specific" and "user-specific".
If you need help creating a new user account to check whether your problem is "user-specific" during Troubleshooting, see this Help article.
(3) If resetting or the other suggestions do correct your problem, try the following:
• Backup your Home Folder, or at very least, your important files.
• Repair permissions. (Click here if you need help.)
• Then download and apply the Mac OS X 10.4.10 Combo Update v1.1 (iNtel).
• Finish with another Permissions Repair, and then check your iSight again.
Users have reported fixes to a variety of audio, video, connectivity, and software conflicts and unreliability issues after properly applying Combo Updates.
(4) A few iNtel Mac laptop users have also reported success after unplugging their Macs and leaving the battery out for half-an-hour to overnight.
(5) If none of these suggestions help, contact Apple or your Apple-Authorized Service Provider for a professional check.

Built-in isight camera suddenly stops to work

Almost one year later after buy a Macbook Pro (Mac OS X 10.5.6), the built-in isight camera suddenly stops to work. It was doing well until now. It's a program and user independent bug. During a video conversation, it just stops. It happens when I use mercury or skype (the only video chat programs I use). And just after, when I try to restart the chat, the program doesn't recognize the camera.
Only when I boot the computer (shut down -> cable unplugged -> battery out -> 5s pressing boot button -> battery in -> cable on -> turn on) the problem is fixed for a while... but then the problem happens agains... the problem occurs after the 4th or 5th time Im using the program...
Any suggestions??? Thank you in advance.

HT1338 built in camera has stopped working, how can I update or reinstall the drivers

Built in camera has stopped working, how can I reinstall the respective drivers?

Here are my best suggestions for your camera problem, Stephen:
• If you have not already done so, shut down Mac, restart,
    and try again. If the camera still does not work, continue.
• Try ALL relevant suggestions from Apple's Troubleshooting
   article: http://support.apple.com/kb/HT2090
(Apple has changed the built-in camera's name on newer Macs from "iSight" to "FaceTime" and then to "FaceTime HD." Regardless of the name of your Mac's built-in camera, the same info and troubleshooting applies.)
   If you need to use the "reset" suggestion, use the correct reset for your Mac.
• Use your Mac's Disk Utility to repair permissions and then
   download and apply the latest Combo Update. For your Mac OS,
   the current version is at http://support.apple.com/kb/DL1640
• Repair permissions again immediately following the system restart
   that completes the Combo update.
Properly applying the Combo version of updates can sometimes correct software problems, but, if your trouble is caused by a hardware problem, there are no user serviceable parts of the camera.
• If nothing else resolves your problem, yours is likely a hardware issue.
   Unless you have a current backup, make one now.
Then use the final "Troubleshooting" suggestion:
"... contact Apple or an Apple-Authorized Service Provider for service."

My macbook (purchased in 2007) Mac OSX Lion 10.7.5 camera has stopped working - tried on Skype, Facetime, and Photobooth. Any ideas how to fix this?

If restarting doesn't fix, use the relevant suggestions from Apple's How to Troubleshoot iSight. If nothing else there works, the repair by an Apple-Authorized Service Provider suggested there and by spudnuty will get it sorted.

Built-in iSight camera doesn't work all the time...?

This started on iChat... When starting a video conference I see a black picture, the green light turns on but my buddy only see's a video of herself and is still able to hear me. I tried opening the audio/video preferences and the preview is still black. I also tried opening photobooth and it shows a black picture as well. This only happens on occassions, it works most of the time but this problem seems to be occurring more often. I've tried all the troubleshooting listed but nothing seems to work..?

"I've tried all the troubleshooting listed but nothing seems to work..? "
Please list them. This will avoid the +"been there, done that"+ scenarios when users try to provide you with troubleshooting solutions.
Otherwise, +"since you've tried all the troubleshooting listed"+ then send your computer to your local AASP or contact AppleCare if you are still under warranty.
Tried everything in Article http://support.apple.com/kb/HT2090 How to Troubleshoot iSight and this thread my isight camera is not working-not recognised with photo booth or ichat?

Satellite T130: inbuilt web camera has stopped working

Hi, I have the same problem of the question bellow, like I have looked around and I was not able to find the answer I need.
I have a Satellite T130 and, suddenly, the inbuilt web camera has stopped working properly. A blue light is on, but there is no image. What can I do?
Thank you

Hi,
the blue light is beside the web cam, on the top of screen. But this light is on when I try to use the web cam in anywhere, like Skype, Msn or even in programs in the computer that only take a pictue or make a video of you, without ineternet (I do not know the name of this program). But it seems that computer and the programs recognize the web cam, because there is no messages when I turn on the web cam.
In Skype settings is the same, there is nothing wrong, there is no different message. The only thing is when I try to take picture a message appears: "failed", but the video seems to record normally, although everythng is black.
Could you understand what I meant?
Sorry about my english....

My built in camera has stopped working since Skype...

Since recent Skype updates the camera has stopped working - but it works in other applications. I am running on Windows 7 - do I need to uninstall and load n older version - anyone else suffering these problems?
Solved!
Go to Solution.

You didn't state what camera you are using. There have been some issues with Dell XPS models. If that is the case, the problem has not been resolved as of yet. You can try downgrading to an older release to see if the camera works once again.
You have two options to try to resolve this:
1. Try 3rd party software like manycam (manycam.com). See if your camera works in the manycam software. If it does, select the manycam virtual driver in Skype and see if your camera still operates with the latest release. If you go this route be sure to do a custom install to install only the main program.
2. Your other option would be to revert/downgrade to a prior release or a version that exists to address video/camera compatibility issues like the Skype special version:
Skype 6.3
http://download.skype.com/msi/SkypeSetup_6.3.0.105.msi
Skype Special Version (6.1.999.130):
http://www.skype.com/go/getskype-sse
Depending on which versions work may determine if the compatibility issue was introduced in the newest versions or if you camera is not compatible with the new way video is rendered (Skype 6.2 and above).

My FaceTime HD camera has stopped working on my 2013 11" MacBook Air.

Recently, my FaceTime HD camera has stopped working. The green LED indicating that it's on will turn on for a second, then turn off. The camera is never activated, and it constantly repeats this cycle. I contacted Apple for help after I had tried repairing permissions, resetting the SMC, and reinstalling the OS as a last resort. I don't know what to do at this point. I'm running Mac OS X Mavericks, and the camera had no problems with the OS. The camera has just suddenly stopped working. Can anybody please help?

See this thread:
https://discussions.apple.com/thread/5306216?tstart=0
FIX:
1. You need Time Machine
2. Go to folder /Library/CoreMediaIO/Plug-Ins/DAL/
3. Copy AppleCamera.plugin to good place (usb memory stick is the best place).
4. Go to Time machine in date that skype work fine.
5. Change AppleCamera.plugin with file from Time Machine
6. Restart system, Now skype need to work with camera.
If that doesnt pass,
Suggest looking here, much success has been found:
