Macbook Pro camera turns off and back on.

When I am videochating with my friends or for any reason I have my camera on, most of the times the camera turns off (Green Light Off) and then back on. While the light turns off my video gets stuck and then when the camera turns back on the video continues to function normally but it bother me a lot because it is a new computer I just bought for christmas and whenever I am videochatting the camera turns off and back on. PLEASE HELP!

Thank you for your detailed troubleshooting attempts.  Very helpful.  Sorry, I cannot read "logs."  My eyes just glass over on those things.  Hopefully, a knowledgeable user will come along shortly to decipher for you.
I noticed from the pics that your location setting is "untitled."  Have you tried the "Automatic" setting?  Run the diagnostic test?  Results?
Try the basics first:
   Change your router channel number.  Most times this works & is all you have to do.
Disconnect & reconnect your modem.  unplug it for about 10 seconds.  Plug it back in.  Do the same for Apple’s routers.  Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

  • My one day old MacBook pro just turned off and it won't come back on either through mains or battery power

    My one day old MacBook pro just turned off and it won't come back on either through mains or battery power it's as if the unit is completely dead. Even with the mains plugged in there is no green or orange light to say its charging or full charged. The battery was fully charged anyway seconds before the screen went off.

    When you say no green or orange light are you refering to the little led on the magsafe connector?  That could mean either the charger/cable are bad or the circuitry in the MBP is faulty.  Since this is a brand new MBP best bet is to take it back to an Apple Retail store and have the genius bar staff take a look.  They can determine if it needs to be reparired or replaced.

  • Macbook Pro - WiFi turns OFF and won't turn back ON

    Hello,
    this is my first time posting something on this forum; I will be as detailed as possible. I bought a Macbook Pro back in 2011 and It came with Lion OS. Last year I upgraded it to Mavericks and so far it has been a nice experience. However, in the past week I have experienced a very strange and irrating problem with my macbook. While doing work all of the sudden the WiFi would turn off and lose all connection to the web. I attempted to turn it back ON by clicking on the wifi signal icon but something weird occured, it was still 'ON' according to my mac and the only option available was to actually turn it OFF, so i clicked on it and the icon would go empty with no curvy lines (i attached a picture). Then i clicked again on the icon to turn it back on, however, as was doomed to remain in this state cause no matter what I tried.. the wifi will remain off even after clicking on the 'turn wifi on' option multiple times. I tried going to the assist me option under network preferences and I obtained multiple results with no fix. I tried sending my mac to sleep though at first seemed to fix the problem.. the wifi inmediately went back to being off and wont catch a signal. The only thing that fixes this is a fresh restart which is annoying and unacceptable...this is really annoying and I need a solution asap because this problem is become very frequent (once every 2 hours)... any help will be appreciated it.
    I attached 2 pictures and the console log when this happened.
    1. A picture of my assist me window before i sent it to sleep, shows the WiFi on the left with the 'Failed' (which confuses me). it also shows the wifi icon empty ( like it was off) but the computer shows as if it was on and would ask you to turn it off... weird?
    A second picture after I sent my mac to sleep. Though it seems like there was no wifi signal available, the router was on and literally next to my mac...but my machine wont catch up the signal. (other devices were connected to the wifi and have no problem with it).
    Here is the console log right before and after my this problem occured:

  • My macbook pro suddenly turn off and now when I turn it on the display doesn't work but it is on!

    Hello everyone,
    My macbook pro 15" suddenly turned off. Now i tried several time to switch it on and seems it is working but the display doesn't function or there are many wired pictures coming up sometimes.
    can anyone please help me with this issue?
    Thanks

    Welcome to the Apple Support Communities
    Your Mac can't find any bootable partition.
    1. Insert the Mac OS X DVD that came with the Mac and press C key while your Mac is starting.
    2. Select Utilities > Disk Utility, choose Macintosh HD in the sidebar and repair the disk. If it doesn't work, take the Mac to an Apple Store.
    Also, open  > Startup Disk, select Macintosh HD and restart. Maybe your Mac has forgotten the startup partition

    My 2009 Macbook pro 17 turns off and goes dead when switching to "high performance" graphics in the energy saver controll panel.

    The battery is new, from june this year.

    It will not do any harm trying it but you are probably correct in these circumstances. 
    If the symptoms are consistent, then a savvy technician at an Apple store genius bar should be able to define the problem.

  • IMac 2008 emc 2211 suddenly turns off and back on, RAM problem?

    I have an iMac from 2008 emc 2211.
    Two years ago i upgraded my RAM from 2GB to 4GB Crucial memories.
    Two weeks ago my imac started to suddenly turn off and back on inmediatly. Recently it stared to happen more often to the point that it can't boot completely and show the desktop
    I checked the power source and it was fine.
    I opened the computer and pulled out the power supply and it seamed to be fine.
    I tried to run the hardware test with the disk that came with the computer and it can't even finish the test because it turns off.
    Before it couldn't boot anymore i checked if it was overheathing with smcFanControl and the temperature was always around 44C, so it was fine.
    Could this be the crucial RAM that is failing?
    thanks in advance.

    Ok, i've replaced the RAM and the power supply and the problem persist, so it seams to be the logic board that is failing.
    Any ideas?

  • Macbook Pro suddenly turned off, not charging either.

    My Macbook Pro suddenly turned off last night. I've tried all the troubleshoots listed in the user manual. Thought it was just batt low but it would not even charge, neither the battery sign located on the left side wouldn't show any sign/blink/color. Please help me, it's just 8-month old and Im not sure what could be the reason of this problem. PLEASE AND THANK YOU

    Welcome to the Apple Support Communities
    It looks like your NVIDIA graphic is damaged. If you need your computer now, you can fix the computer downloading gfxCardStatus and selecting the option to use only the integrated graphic, so that kernel panic won't appear anymore. Note that you won't be able to use the NVIDIA graphic, so the graphic performance may be worse than with this graphic.
    Of course, that's a temporary fix, because you should take the computer to an Apple Store as soon as possible to get the Mac repaired. As the NVIDIA graphic is not soldered, the repair won't be expensive

  • My MacBook Pro will turn on and get to the login screen. After I login though it goes to a white screen.

    My MacBook Pro will turn on and get to the login screen. After I login though it goes to a white screen.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

  • In updating my iPod to 6.1.2, I received an error during the update.  Now, ipod is not rebooting.  Has screen showing usb to Itunes picture.   Turning off and back on it goes back to this picture.  I don't know how to reset so that I can restore my backup

    In updating my iPod to 6.1.2, I received an error during the update.  Now, my ipod is not rebooting.  It continues to display a screen showing usb to Itunes picture.   Turning off and back on, it goes back to this picture.  I don't know how to reset so that I can restore from my backup.
    A similar thing happened when I updated the ios on my ipad.  But, I was able to reboot, and then restore from backup.   How can I get my ipod to reboot and allow restore when it is not even recognized as I reconnect to my computer?

    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode
    How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - Try on another computer
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • Nokia Asha 303 turns off and back on again constan...

    Hi,
    since a few weeks, every day my phone starts to turn off and back on again by itself, and this 10-20 times. Then it works fine again for a few hours and the whole thing starts again. I've also noticed I have to recharge my phone every day.
    Some help please? :-)
    Thanks!

    As said by Farby above, you might need to visit Nokia care centre.
    Back-up important data before going to the Nokia care.
    Hope this helps.

  • My iphone 5 will freeze up and turn off and back on. It will go to the apple screen and then go black MULTIPLE times before it comes back on. No buttons work while this happens. My phone is a week old.

    My iphone 5 will freeze up and turn off and back on. It will go to the apple screen and then go black MULTIPLE times before it comes back on. No buttons work while this happens. My phone is a week old.

    User troubleshooting is restart, reset, restore from backup, restore as new. If you perform these steps and it still doesn't work, then make an appointment at the Apple Genius bar and have the hardware checked.
