Screen Darker In The Middle

I have noticed that the screen is much darker in the middle of the screen, vertically in a column. This was improved when i booted to the CD. Now on a fresh install and it looks better but doesnt seem to be completely fixed. I am going to wait and let the screen heat up. Also is there any fix for the high pitched noise yet?

hmm...I just received mine literally 20 minutes ago, and my screen is considerably darker on the right side (especially along the right edge). And I have this backlighting leaking on the upper right corner. I am going to wait a day and see if that clears anything. If not, it's going back....sigh...

  • Why is the left side of my iMac screen darker than the other, and why does the display randomly go black?

    My family has a late 2010 27" Imac. A few months ago, we noticed that the left side of the screen was somewhat darker than the right. As time went on, it continued to get worse and worse. When you turn the computer off for an hour or so, it helps the display out somewhat, but it eventually goes back to being darker on the left. About two months ago, the display started to go completely black. When the screen is black, everything still runs. My itunes library will still play, everything is functioning even though the screen is out. It has started to become more frequent. It is extremely annoying, almost unbearable. Since the one year warranty went out in November, what are we supposed to do about this?

    Contact Apple Service, iMac Service or Apple's Express Lane. It's a known issue with 27" iMacs and you might be eligible for replacement. I had mine replaced shortly after buying it. BTW, AppleCare's extended warranty is the cheapest insurance policy one can have for desktop machines. Too bad you missed the deadline.

  • LCD Screen cracked down the middle

    My Iphone has what I think a broken LCD screen down the middle. It does not let me unlock the phone to get into the main screen because of that crack down the middle. The outside glass is not shattered or anything. I can only answer calls using my headphone devise but not make calls. Does anyone have any suggestions or do you know whether apple can fix it for free under the warranty. I don't recall dropping it. Thanks.

    If it was like that from day one then thats was manufactured wrong and take it back to Apple.
    If not then they could blame it on you as abuse, you will not be sure until you try..

  • Screen darker towards the bottom.

    Apple put in a new hard disk in my iMac. The bottom of my screen is darker than the top and how can I fix this?

    Take it back, however remember your machine is close to 7 years old so it may be time to just get a new machine

  • Top 1/3 of screen darker then the rest..  23" HD

    A few weeks ago the top 1/3 of screen got darker then the rest.. It seemed to go in and out from 100% to dark for about a week and now it is just darker. The monitor is still usable but it gives me a head ache after a while of working.
    Can this be repaired by apple? Any suggestions would be greatly appreciated..
    Thanks and happy holidays....

    Happened to me and I thought it also was the upper cfl tube, it got progressively darker by the week. Instead of changing the cfl tube, I swapped the inverter board from an exact model that was used for parts. I figured that an inverter change was much easier to do and it was and the problem was solved, works like new. Sometimes it is not always the tubes that go bad, the inverter board is divided into 2 sections, one for the lower tube and one for the upper one that supply the tubes the voltage. If voltage is weak, so are the tubes. If the power button on the monitor flashes it is almost a sure sign of inverter problem. Tubes and inverter are really not that difficult to change, just the right size allen keys and a philips screwdriver and a little patience. Check out moniserv.com for schematics and parts. They also have some very useful suggestions.

  • My ipod 5 screen flickers down the middle of my screen

    i bought my ipod 5th gen back in december. it mostly sits in my car and charges off of my aftermarket cd player. occasionally when it dies ill take it inside and charge it on my wall charger. today it died and i plugged it inside for 2 hours and it would still not turn on. finally when i got it to turn on there is about a 1 inch wide bar flickering from the top to the bottom of the ipod. its not turning black or white its just flickering brighter to lighter. the ipod touch 5 doesnt have auto brightness so i dont know whats going on, please reply if you had this problem and fixed it.

    Since it will still be in warranty, I would recommend a visit to the Genius Bar. They will tell you what the issue is here and should have you sorted. http://concierge.apple.com/reservation/gb/en/techsupport/ Your iPod should not be doing what it is doing and also remember to tell them about everything you have stated here. I have included a link to make a reservation above.

  • Mac book pro has grey screen with apple in the middle

    my mac book pro has a grey screen, apple in the middle and a spinning wheel.  i have tried the command r. nothing is working

    Mac OS X- Gray screen appears during startup
    Question (?) Mark, Blinking Folder, or Gray Screen at Startup
    These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
    A flashing question mark appears when you start your Mac
    Mac OS X- Gray screen appears during startup
    In most cases the problems may be caused by one or more of these:
    a. Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
    b. Boot drive's directory has been corrupted - Repair with Disk Utility.
    c. Critical system files are damaged or deleted - Reinstall OS X.
    d. The disk drive is physically non-functional - Replace the hard drive.
    Note that the information I have provided is what Apple recommends, If other users suggest different solutions than found here, then be sure what they recommend does not impact on your warranty, if any, or ability to get continuing Apple service.
    Please don't start removing drives or changing cables unless you know what you are doing and have exhausted other non-invasive alternatives outlined here. If you perform any work yourself that is unapproved by Apple, then you will void any warranty you may have and lose all further Apple Support.
    Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD. Simply boot from the Recovery HD to perform the above.

    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    Reinstalling Lion/Mountain Lion Without Erasing The Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed.

Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

  • How can I stop my phone from muting in the middle of calls?

    When pressing "send" and making a call, Six boxes pop up on the screen, one of them being the muting option.   My problem is that face or ear touch this button while I'm in the middle of a call.  I need to be able to manipulate the options that come on the screen everytime a call is placed, in this case being able to have no options on the screen while in the middle of a call.  Is this possible? if not, it should be; on the next upgrade.

  • Is there a dark-red pixel in the middle of my ipad 2 screen, Apple Staff ignored it with rude manner.

    Is there a dark-red pixel in the middle of my ipad 2 screen, I 've just it for 6 days. After that I went the store (Thailand) to turn it, they told me that it's a dead pixel and Apple won't replace it to the new one - there must be more than 3 to claim.  How can I do?
    The store guy told me I should go Apple Service Center. The Center's staff kept my ipad and told that replacement depends on Regional office at Singapore.
    She also blame me that "Why don't you look for dead pixel before you brought?"
    What !!! Dead Pixel is the fault of Apple Factory, but she said like I'm so stupid to brought a dead-pixel ipad.
    "If you want me to do something on your case call to Singapore by yourself" she said.
    After I called to Singapore, I found myself the staff there treated me so bad and confuse.
    1. The first guy at Singapore said  "Because you 've just brought it for 6 week you can choose between replacement or refund, but leave me your numbers we will call you back."
    2. Shortly, a rude guy called me - said to me about Bright and Dead Pixel - then said "It's not our authority to replace ipad for you, you paid your money for our dealer (Store in Thailand), so you must ask for resposibility from them. "
    What !!!!! He treated me like I'm not a customer. Store and Care Center in Thailand told me it ups to Singapore, but Singapore told me not.
    Who lied? However, I'm still Apple Customer. Whatever country I brought it, I paid for Apple product. Where are thier responsibilities?
    I hope, Apple U.S. is my last resort.

    Given that you can return/exchange it for any reason within the 14-day window after you bought it, you shouldn't have any problems.
    Do you live near an Apple retail store? That may be your best bet. It certainly worked for me: I ordered mine online and when I noticed an air bubble embedded in the glass, I brought it to my local Apple Store and 15 minutes later walked out with a replacement. No fuss whatsoever.

  • Do I have to live with dark/dead pixels with my new 15" MBP? Yesterday I bought one and have one dark spot in the middle of the screen.

    Yesterday I bought a 15" MBP and found a dark spot in the middle of its screen right away while in the 1st-time-welcome-boot. What a welcome. Do I have to live with it? It is exactly one pixel missing its yellow subpixel. It would be ok if it would be in some corner - but its right in the middle of the screen. Suggestions/experiences in this matter anyone?
