MACBOOK - MY SCREEN BRIGHTNESS KEEPS FLICKERING

HAD THIS MACBOOK FOR APPROXIMATELY 2 YEARS NOW. WITH THE AC ADAPTOR IN, AS I USUALLY USE IT, THE SCREEN ON MY MACBOOK HAS BEEN "FLICKERING", THAT IS BECOMING BRIGHTER AND DIMMER. ANYONE ELSE HAVE THIS PROBLEM? DO I NEED TO BRING IT TO THE STORE FOR REPAIR. I ASSUME THAT SOMETIME SOON, THE SCREEEN WILL GO COMPLETELY BLACK, IF I DON'T DO SOMETHING SOON.
ADVICE, PLEASE.
THANKS,
TWON

Regarding the flickering screen, the usual solution is to replace the inverter board. You need to take your MacBook to an authorised repairer. I hope you took out the extended warranty or it will be expensive.

  • Won't respond.  Have a blue screen that keeps flickering.

    My MacBook pro is not responding.  It has a blue screen that keeps flickering.  Power button does not even work.

    Safe Boot by restarting your computer while holding down the "shift" key.  Safe booting disables all nonessential processes, often times allowing you to start up when you would otherwise crash.
    As of OS X 10.5.6 Safe Boot deletes the dynamic loader shared cache location in the /var/db/dyld directory.  A corrupt cache here can cause the blue screen crash.  Once you restart normally, the cache will be recreated.  This should take care of the issue.

    Have you tried a Safe boot? Left side SHIFT at power up, hold till you see the progress bar then release and allow to finish booting,. (note this will take longer that usual) Thsi will disable 3rd party software/extensions. Login and see if the issue still persists, if not logout and boot normally.
    Another thing you can try is creating a test account and see if it has the same issue there, this will help determine if it is related only to your account.
    Also check About this Mac (Apple logo) option, system information, power in the left side bar and check the battery info.
    If you have already tried these steps, you should include what you have already tried so people will not offer redundant suggestions.
    If you still are having issues, it looked as though you were typing that you thoght you may still be under warrany, if so you may want to take it in and have it checked out, as there the keyboard/screen issues along with the no wake on battery, it may be related to a battery problem?
    You can check warranty status by going here and entering your serial number.

  • 2012 Mountain Lion Macbook Pro screen brightness control disappear

    Hi everyone, MY macbook pro bought in 2013 but it is a mid 2012 cMBP 15 inch, it don't have any problem but until recently, the screen brightness control just disappear, I don't have any os x update, still using 10.8.3 version, and I searched the web and most people will just reset the NVRAM by hold the cmdoptionP+R when in the start up screen and I do that too but the screen brightness control just won't come out and the F1 and F2 won't function neither, but the keyboard light key do function & if I press the Fn + F1 or F2 it will has a alert sound which show that the F1 & F2 don't have problem but the special function printe on them(screen brightness control) won't work!
    WHy?
    I need yr help!!!!

    JohnnyChin95,
    reïnstalling OS X will probably be the only real solution. Will your house have Internet before your warranty expires? If not, then it would probably be better to send it to Apple, even though there would be a long wait to get it back; you’ve paid for the warranty in your purchase price, so why not make use of it? (You might also want to consider purchasing an AppleCare plan; you can do so any time before your original warranty expires.) Alternatively, do you know anyone with Internet access who would be willing to let you download OS X onto your MacBook Pro at their home?
    To my knowledge, all of the original MacBook Pros are manufactured in China; I don’t know where in China, though. If you received a box that has a sticker with your MacBook Pro’s serial number, Ethernet MAC address, Wi-Fi MAC address, &c., and all of that information matches what’s in your MacBook Pro, then that’s probably a good sign that you have an original Apple product.
    In my case, I have a relatively slow 3½ Mb/s downstream DSL connection, so it took about five hours for me to download Mavericks. If your Internet speed will be faster, then your download time should be proportionally shorter.

  • Screen Brightness Keeps Dimming

    My new Sony SVS131290X laptop will not keep it's screen brightness lit.  It keeps dimming by itself.  I have tried setting the function + F6 key, going to power options and adjusting the brightness there, and also tried advanced power options.  It dims after 30 seconds.  Has anyone else had this problem?

    Hi everyone, I just recently purchased a Sony Vaio Pro 11" and I have been struggling with this issue the past 2 days, and now I have a proposed solution! Prior to doing this I had tried two things (outlined below) and neither of them fixed the issue for me, so if you are in the same boat this might work for you too. WHAT WORKED for me was going to the graphics properties control panel:Right click on the Desktop home screen and select "Graphics Properties" > click the "Power" tab > click "On Battery" > and under "Display Power Saving Technology" click OFF That fixed all my auto-brightness adjusting woes. Hopefully this helps someone else  The two steps I took that didn't quite work:1. Went to Vaio Control Center > Image Quality > turned OFF the auto brightness = still had the dimming issue2. Went to the Start screen, scrolled down to the apps section and in the search bar > typed services.msc > opened up Services > clicked "Sensor Monitoring Services" > went to the drop down menu and changed from "manual" to "disabled" and restarted my laptop = still had dimming issue  

  • BB 9860 torch wont unlock pressing button and when it does the screen just keeps flickering

    Hiya, i wonder if this is a common problem or its just my phone
    I recently bought a BB torch 9860, it was working fine but now when the screen locks, when i press the unlock button on the top of the phone it does nothing and just says "Screen is locked, press the lock button to unlock" and all the screen does is lights up then goes off in like a flickering manner
    obviously it shouldnt do this
    When i take out the battery and put it back in the screen loads fine as normal (no flicker) but once its back on the home screen i just get this annoying lock problem and a flickering screen
    Any help or information would be appreciated
    Thanks dwain

    Yes, it's normal behavior for the Voiceover function.
    It's designed for the visually impaired.  If it helps, try using your iPhone with your eyes closed.  With the first tap, VO begins to read what is on the screen. When you hear the item that you want to select, tap the screen (anywhere) a second time. 

  • MacBook Pro screen saver keeps going back to default settings

    I use the Vintage Prints screen saver and always change the folder of photos to the most recent folder of photos I have taken. (I am an avid photographer and take lots of pictures.) Periodically the screensaver reverts back to the default settings: National Geographic photos, not shuffling the slide order. This has happened multiple times. Why won't it keep my settings?

    Well try upgrading the firmware of the router & keep on holding tightly the reset button in such a way that power light is blinking on the router & then do a complete network power cycle i.e., unplug the power cables from the modem & from the router & then plug in the power cable to the modem first once all the lights are solid green you could plug in the power cable to the router & check out it will definately work!!
    Open the setup page of router using 192.168.1.1 then put in the password as admin...all you need to do is do the wireless settings such as Radio Band Frequency to Standard 20 MHZ frequency,channel to 11.
    Also,the advanced wireless settings to Beacon Interval=50,Frag
    thres=2306 & Rts thres=2307 & then uncheck a Block Anonymous Internet
    Requests & it will definately work!!!

  • Macbook pro 2011 early cannot find right resolution for external display and keeps flickering

    I have a macbook pro 2011 early running 10.9, and a LG FLATRON W2242T external screen. Also, I have a VGA to miniport from Apple and a VGA to HDMI, plus a HDMI to miniport(from Apple). By just connect with VGA to miniport to my MBP, it just flickers few times and stops detecting. But by connect VGA to HDMI converter and HDMI to miniport to my MBP, it keeps flickering, a non-stop flickering. The external screen always shows no signal. However, if I connect my MBP to my TV through HDMI to miniport, it works fine. But connecting the VGA port to my TV, it gets the same problem. I have tried clear my PRAM many times, and it gets the same result. Does anyone have the same problem? Thanks

  • Macbook Pro 13" Screen Distortion and Flickering

    Hi Guys,
    please help me if you can, got this problem where the screen keeps flickering and distorting... got a couple of videos here, need some help!.

    http://www.youtube.com/watch?v=XhthT9XHIus&feature=channel (not so frequent)
    it shouldnt bug me, but its a £1000 laptop which has problems?

    That should definitely bug you! I'd go crazy.
    Generic advice time: Looks faulty. First I'd start with making a full backup of your drive, then reinstall snow leopard fresh.
    If you get no luck, then it's probably a hardware issue. If your laptop's new, take it back. If it's an old laptop but this is a recent development, you may have to get it repaired. Whether you do this through the apple store or a third party is up to you.
    Hope this helps

  • MacBook Pro 13" screen brightness

    I just bought a 13" MacBook Pro and find the screen brightness and contrast is much less than expected. It basically has to be turned up full on AC to be acceptable, which is very unexpected, since I am typing on a 16 month old MacBook Air now that is about the same at 80% of screen brightness. The contrast is less pronounced on the new machine, too, and the notion of 60% more color saturation seems faulty. I am going to return it and see if the Apple Store thinks this is normal or a faulty screen. Am I being unreasonable to think the new MBP screen should be at least equivalent to the original Air screen?
    Message was edited by: MacBook

    Yes, I agree that there is something different about the two displays. I conducted my own side-by-side comparison -- in the same room lighting, and also switching the places of the two machines -- and found at any given setting, the 13" MacBook Pro was darker than the MacBook Air. Furthermore, when I first started the machine, the MBP's keyboard backlighting would not go off, no matter the lighting. Then, when I went to make these comparisons, the MBP's keyboard backlighting would not come on.
    This linked picture is a composite from two pictures taken in succession in the same lighting and angles, just as they came out of the camera, showing the relative brightness of the two. http://farm3.static.flickr.com/2547/3844348963e76728bce2o.png
    So, I packed up the machine for a trip to the Apple Store and either an exchange or a return.

  • I have a MacBook Pro running mac osx 10.8, Screen saver keeps reverting to national geographic photos.

    I have a MacBook Pro running mac osx 10.8, Screen saver keeps reverting to national geographic photos.

    Just found this solution on another website. I tried it and it works. No more polar bears and Savannahs!
    Apparently if you put it in the folder called "Desktop Pictures" it will work.
    So, copy whatever folder of pictures you would like to use as your screensaver and then go to:
    Macintosh HD>Library > Desktop Pictures
    Paste your folder into this folder called "Desktop Pictures".
    You may have to enter the administrator code (the password you use to open your mac usually).
    Then, go back to System Preferences, go to Desktop and Screensaver, click on the Screensaver tab on the top, go to the drop down menu beside "Source" (under the picture) and click on "Choose Folder". Navigate to the Macintosh HD>Library>Desktop Pictures and then click on the folder you just pasted in there. Click "Choose" and you're all set.

  • MacBook Air Ambient Light and Screen Brightness

    I've installed windows 7 on my macbook air and everything is working great for over a year now. The only thing that's not working is the auto adjustment of the screen brightness. I It is working on MacOS but not on Windows 7.
    Thank you,

    This is one of those situations where the word "probably" applies. It just depends on whether you want to trust a product with no stated applicability to the purpose for which you intend it.
    I think I would stick to products either indicating that they are safe for use on computer LCD displays, or follow Apple's recomendation of using just water to moisten a lint-free soft towel.
