Display randomly turns off

I will be using my Macbook Pro, and the screen will randomly shut off, and the light that tells you it on in front edge turns off. When i close the lid it comes back on. All my keyboard lights are still on when i open the lid. I did just have apple replace my Logic Board. The computer turned off and wouldnt turn back on, that was fixed with the logic board replacement though.

Thanks for the quick response. Any idea how that could be fixed? And would monitor problems create any issues with the operation of the rest of the computer? I did forget to mention (sorry) that when these issues arise, the sound will often loop, much like a 'broken record.' I didn't know if that would help. Thanks so much!

  • Display randomly turns off; will applecare cover?

    Hi all, quick question.
    I've had my iBook G4 for two years now. I love it. However, it does this weird thing every once in a while where the backlight just shuts off. It usually does it if I pick up the computer in order to move it somewhere, if I bump the display (not hard, mind you), or if I set it down. It'll do it pretty much any time I jolt the computer. It also does it randomly sometimes. The only way to fix it is to shut the screen, wait for it to go into sleep mode, and then open it up again. This gets pretty annoying when you're trying to work on something.
    So, I was thinking about sending it into Apple with my Applecare, however, I wasn't sure if they would cover it because its an intermittent issue.
    My speakers also do this crazy thing where I'll be watching something and they'll send all the sound to one of them or another. It sounds like one of them is going dead. However, this is also an intermittent thing.
    So basically, my question is this; should I waste my time and money sending my pc into apple when my computer might not even "perform" the problems for them? Or, should I just deal with it?
    Thanks for your input!

    Hi,
    The symptoms point to a logic board problem but you'll need to tell them how to duplicate the problem. I had the same problem with mine and sent it in for repair. They couldn't duplicate it and sent it back. I found I could cause it to freeze by pressing on the top case next to or just below the fn key. I then took it to the Genius bar and was able to duplicate it with the Genius watching. Apple replaced the logic board and it's been fine since.
    For your sound problem balanced-1.0 (freeware) can correct it or if you're using an early version of Tiger, updating will probably correct it too.

    Hello there, LaruaGalliers.
    The following Knowledge Base article provides some great troubleshooting steps for your issue:
    iPhone and iPod touch: Charging the battery
    http://support.apple.com/kb/HT1476
    Particularly:
    Battery does not charge
    Verify that the outlet being used is working.
    Try another USB power adapter if available.
    If no other USB power adapter is available, try connecting to a high-power USB 2.0 port (not a keyboard). The computer must be turned on and not in sleep or standby mode.
    Try another USB cable if available.
    iPhone or iPod touch displays the low-battery image and is unresponsive
    If you see the image below, charge the iPhone or iPod touch with USB power adapter for at least 15 minutes.    
    You should see this image when iPhone or iPod touch begins to charge:
    If the screen still displays the low-battery icon, try turning the iPhone or iPod touch off and then on again.
    If the issue persists, follow these troubleshooting steps.
    Thanks for reaching out to Apple Support Communities.
    Cheers,
    Pedro.

  • Screen randomly turns off or dims

    I have an iBook G4, and every now and again the screen randomly turns off. It doesn't respond to pressing and holding the power button, the only way I can turn it back on is by both taking out the battery and unplugging it, waiting 30 seconds, putting the battery back in and restarting it. If I put the power lead in before restarting then the display switches off almost instantly during boot up.
    Other times the screen randomly dims really dark so that you can only just see outlines, in this situation it responds to pressing the power button and then enter to shut it down, and then after booting it back up it's fine ...until the next time.
    The problems happen as often as every five minutes on some days and then not at all on others. Both occur when using the battery AND power lead, often (but not always) when the power cord is moved. Also I can get my power cord to flicker between green and orange if I wiggle it - not a good idea I know, I don't do it regularly
    I've tried resetting the PMU with no success. Also I've tried swapping my battery and power lead with a friend, they had no problems using mine (and couldn't replicate the green-orange flickering), and I still had problems using theirs.
    I read someone else's topic with suggested that the problem could be deficient soldering on the DC-In Board, so I've had a look. I'm no expert but the soldering looks ok to me, except one of the 3 metal legs connecting the actual socket bit to the board (the one which would be at the bottom under the yellow tape in http://www.macrecycling.com/images/products/922-6254.gif ) is looking a bit black and has discoloured the yellow tape black immediately on top of it. Looking at the circuit board though, this leg doesn't seem to connect to anything!
    I've read numerous topics regarding similar situations and popular diagnosis include problems with:
    * battery/power lead (I'm pretty confident it's not this)
    * DC-In Board
    * GPU
    * Inverter cable
    * Inverter
    * Backlight
    From the information I've given does anyone know what is most likely the cause?
    I'm a poor student, my iBook's well past it's warranty, and I hear repairs start in the £100 region (also I've rumours the apple stores have stopped taking in iBooks for repairs now). So home repair is pretty much my only option at the moment, and any advice would be greatly appreciated.
    Thanks in advance

    I had the same trouble, but today my iBook died after draining the battery. It just drained it and it did not charged the batt while connected, also the iBook makes a small buzz sound while connected (and it does not do so while powered by the batt).
    I researched and found that it is the DC board's fault, because it failed at charging while working fine on pure battery power.
    i confirmed because powering up always worked perfectly while on battery power, (just as in your case).
    The blackness you describe is possibly a short circuit, and you should look into it as quick as possible, before you get to a situation like mine.

  • I upgraded my iPad (first gen) to iOS 5.1 and now it will randomly turn off.  How can I fix this?

    Thread title pretty much says it all.
    Shortly after upgrading to iOS 5.1, my 1st gen iPad started randomly turning off when I wasn't using it.
    -This has been occuring for over a month now.
    -It has not yet turned off while I'm actually using it, only after I've left it along for awhile
    -If I leave it plugged in, it doesn't turn off
    -I have trouble turning it back on after this occurs.  (I have to press/hold the button several times before it will finally turn on)
    -I've noticed that a lot of the time when I turn it back on, it will initially (for a second or two) show a battery % that is lower than what it actually is (ex. it will show 72% when I turn it on but then jump up to 90% after a second or two)
    Seems to me like it's something related to iOS 5.1 that my iPad doesn't like, likely a batter issue.  Although having trouble turning it back on would lead me to believe it might be something more.  It is an iPad 1 so maybe it's just getting up there in mileage.
    Any suggestions on what to do?  I neglected to take any backups.  Unless someone gives me other input, I'm planning on taking a backup of my current iPad and then restoring to factory settings just to see if that will solve this issue.  Although that's going to be a pain in the butt to get all my apps and everything back.  If I restore to factory settings, is there any way I can "upgrade" the to iOS 5.0 (or anything below the latest)?

    No, you haven't lost anything.  Simply sign into your iTunes account on the computer.
    As for the device not syncing, what specially happens when you try to sync?

  • HT6154 My iphone randomly turned off out of nowhere. I was getting dressed, my phone was working one minute then literally the next it syopped now it wont charge i cant turn it on however the phone is on cause i called it and it rang. What to do? help ple

    My iphone randomly turned off out of nowhere. I was getting dressed, my phone was working one minute then literally the next it syopped now it wont charge i cant turn it on however the phone is on cause i called it and it rang. What to do? help please. I tried putting it in DFU mode but my lock button doesnt work and my phone wont charge so i cant connect to itunes

    There is no reason to put it in DFU mode, a reset should work.  Although, without a working power button it is not possible to reset the device.
    Sounds like it is time to replace the damaged device.

  • 30 GB ipod randomly turns off.

    I received a 30 GB ipod as a Christmas gift. At first it worked fine but a couple days ago it began to randomly turn off. I can turn it back on again but it continues to turn off on its own. Any suggestions ?

    My 30 GB did this after I had added some music that I didn't purchase from the iTunes Store. Is this the case for you? Do you notice the iPod turning off when your listening to music that wasn't purchased from iTunes? If so, I just deleted the songs from the playlist and it never happened again. ~.~

  • I was on the phone last night and my phone randomly turned off.  It will not come back on even when I have tried to hold the home button and the power button together while being plugged into the computer.  What do I do?

    I was on the phone last night and my phone randomly turned off. It will not come back on even when I have tried to hold the home button and the power button at the same time, while being plugged into the computer? What do I do?

    Plug it into power for at least 15 minutes.  If it doesn't automatically come on, try a reset... press the home and sleep (on/off) buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.

  • My iPhone randomly turns off by itself with battery remaining. I can turn on the iPhone by hard restart. But sometimes it turns on at fifth, sixth, or more try. did anyone have this problem? and how can I fix it?

    My iPhone randomly turns off by itself with battery remaining. I can turn it on the by hard restart. But sometimes it turns on at fifth, sixth, or more try. did anyone have this problem? and how can I fix it?

    When my phone was off it wouldn't connect to iTunes, i got it working now though. I just had to hold my lock button and my home button down long enough. Thanks anyways though!

    Mostly i researched..they said it's overheating..they said to check if the fan is full of dust something like that..but none of it works..I downloaded a program CoreTemp to check the Temperature for overheating issues..and it's only on 45-50 degrees..and that program has overheating protection to shutdown if it reaches 90 degrees..but in my case in does not reach that degree and still shuts down..hayy..need help badly..

    SO FAR SO GOOD FIX GUIDE-

    Welcome to the Apple Support Communities
    You have a Mid 2010 15-inch MacBook Pro, and your log is showing a NVIDIA graphic card problem.
    Apple has determined that these computers have got a defective NVIDIA graphic card, that may cause unexpected restarts, black screens, kernel panics... See > http://support.apple.com/kb/TS4088
    Fortunately, Apple is repairing all of these computers for free, so just make a backup of your data and take the MacBook Pro to an Apple Store or reseller to get your computer repaired. This repair may take some days depending on the place you take the MacBook Pro, because the whole logic board has to be replaced

  • My Mac book is randomly turning off.

    Hi my Mac book is randomly turning off usually at a little bit under half battery. The computer is about two to three years old and I use it a lot. Why is it doing this and what should I do? I am taking it in to the apple store tomorrow. Around how much will it cost to get in.

    An examination at the Apple store will not cost you anything. Be sure to make a reservation so you don't have to wait too long at the Genius Bar. If there is a repair required there may be a cost for that.
    Have you tried resetting the System Management Controller? That would be the first step I would try for most power related issues.
    Best of luck.

  • My iPhone 3gs just randomly turned off and won't turn back on

    I was just using my phone, and nothing happened. As of lately picture mail, and videos have been sending as a text message to other iPhone users even while connected to wifi. My phone just randomly turned off and won't turn back on. I just got it in July so its not very old and I have the hard protection case on it. Is there any way that I can reset it or something?

    Hold the home and power button down at the same time.
