Parts of screen appear faded immediately after awakening phone

When I first "awaken" my iPhone from sleep, two vertical bars appear on the unlock screen, near the edge of the phone. On both sides of the battery level indicator when charging. I tried pressing the sleep button a few times very quickly - and this makes the issue even more apparent - a full rectangle (with the edges being the faded screen area) is apparent. The issue resolves itself in a fraction of a second - I can see the color "filling in" the faded area.
Just got this phone as a replacement from a defective iPhone, and haven't seen this problem before.
Is it a defective LCD? Something that could get worse with time? Something that would affect image quality? Its just something that is pretty annoying to see..
Anyone else experienced this?
Thanks!

I should add, although this is pretty obvious, this issue isn't apparent if the background is white, but very noticeable if any other color.

  • Screen goes black immediately after booting up

    Screen goes black immediately after booting up....except when just using the battery. If I plug in the cord, the screen goes immediately black, yet it is clear the computer is still working. There have been no hardware changes. Any advice would be appreciated. Thanks.

    junefromoakland,
    are you using your MacBook Pro’s original AC adapter when the screen immediately goes black?

  • Part of screen appears all colored like when you press on a calculator.help

    I was listening to my iPod (5th gen.) today and I look at the screen (backlight's off) and the bottom half of it, maybe more, appeared all discolored like the screen of a calculator when you press on it. Is this a problem I should get fixed with my warrenty? Or is it no big deal?

  • IPhone screen turns off immediately after a message is sent.

    I am using an iPhone 5S (Running iOS 7.1.1) and whenever I send a message, as soon as my finger taps send, the "lock shutter" blacks out the screen and then unlocks itself after a few seconds. Anyone have any ideas?

    Hey there 4cpukid,
    It sounds like you are experiencing an issue where you tap Send in the Messages app and your phone unexpectedly goes to sleep. I would quit all the running apps on the device first:
    iOS: Force an app to close
    http://support.apple.com/kb/ht5137
    Double-click the Home button.
    Swipe left or right until you have located the app you wish to close.
    Swipe the app up to close it.
    When you have done that reset the phone and test the issue again:
    To reset, press and hold both the Sleep/Wake and Home buttons for at least 10 seconds, until you see the Apple logo.
    iOS: Turning off and on (restarting) and resetting
    http://support.apple.com/kb/ht1430
    Thank you for using Apple Support Communities.
    All the very best,

  • Blue screen crash/freeze immediately after Intel iMac goes to sleep

    Howdy all,
    I have a new Intel 24" iMac, less than 3 days out of the box. Almost every time the computer goes to sleep (except twice so far when I first started using the machine) the screen goes dark for a few seconds, then turns light blue and freezes. Neither mouse movement or keyboard input will wake it up, and I have to do a hard reboot. This happens if I put the computer to sleep or just let it happen per the Energy Saver timed settings. Hardware test shows no errors. Screen saver has been disabled. All other settings and software was imported using the setup assistant from my previous iMag G5 running OX 10.3. Tried contacting automated Apple support (newly-reduced live tech support hours are NOT an improvement) and have come up empty. Any suggestions?
    Thanks in advance...

    Quick update, the duplicate of the comic-con episode downloaded succesfully, and so has the first episode of Supernatural season 8. Blue dots appear to their left in the library.
    All the Vampire Diaries episodes (except the bonus comic-con double) have vanished, but I paid for them !
    They're not anywhere on my harddrive either.
    Which is new by the way, this is a new MacbookPro, literally set it up today.
    So it would seem this is a case of purchased and pseudo-downloaded episodes that ended up beinge gobbled up by some iTunes black hole, leaving me with no money, and no episodes.
    Need help, confirmed.

  • I restarted my macbookpro but it doesn't start again. It starts to run and a grey screen appears bus after a few seconds it shuts down. Please help. I can't find anything online

    See if you can boot into safe mode by holding down the shift key immediately after pressing the start button. Keep holding the shift key till a loading progress bar appears on the lower part of the screen. It will take a lot longer than normal to start this way. If you have Lion 10.7 installed you can try holding command-R  keys to get intto recovery mode and run disk utility.

  • HT4623 I updated my ipad to iOS 6 yesterday and it worked immediately after update.  I left home for about 4 hours and when I returned I was uable to get my ipad to come up. I only have a black screen.  When I press the on off button nothing happens.

    I updated my ipad to iOS 6 yesterday and it worked immediately after updating my ipad worked as it should.  I left and came back in about 4 hours and have a black screen.  When I press the on off button nothing happens.  Help.

    Assuming that the battery isn't empty (and it can take up to 15 minutes of charging before it will respond), then have you tried a reset ? Press and hold both the sleep/on/off and home buttons for about 10 to 15 seconds, after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

  • After installing Maverick my computer, when restarted, only a gray screen appeared. My computer won't work at all...what happened?

    After installing Maverick my computer shut down and when it restarted I couldn't get to the home screen. The monitor was grey with some dark grey shapes, it sounded like it was constantly running a program. My computer is sick!! HELP

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
         a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. 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. Post for further instructions.
    Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
    Step 9
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 10
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 11
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 12
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

  • HT1363 after pressing Menu and Select, when the Apple sign appears, I immediately press select and play/pause, but again the red X sign appears. so it does not go to Disk Mode. Has anyone had this issue? I would be grateful if you could tell me what to do

    The red X has appeared in my Ipod Classic Screen. Apple support tells me that I need to first put it manually on disk mode. to put it on disk mode I ought to press menu and select buton togeher, when the apple sign shows up, hold select button and play together.
    After pressing Menu and Select, when the Apple sign appears, I immediately press select and play/pause, but again the red X sign appears. so it does not go to Disk Mode. Has anyone had this issue? I would be grateful if you could tell me what to do.

    Thank you everyone for the replies. It defiantly helped point me in the right direction. With any luck, I will have my replacement phone sometime tomorrow.
    I was able to call the iPhone support line this morning. The Apple rep stayed on the line with me for about an hour until he was sure the new phone would ship out. For $199 plus $29 for expedited handling I was able to get the replacement ordered with overnight shipping. Since the replacement doesn’t involve ATT&T I have no reason to suspect any further delays. Kudos to the Apple rep that helped me straighten out this mess.
    It’s a shame that AT&T cares so little for their existing customers. Not only did they try to sell me the same phone for $499, they outright refused to help me. They also lied to me on numerous occasions and strung me along for close to three weeks for something that only took an hour to complete with the Apple rep.
    I filed a formal complaint against AT&T through the Better Business Burrow as well as requested a review of our cooperate contract with AT&T. Our company currently has over 3000 phones with AT&T and there contract comes up for bid the end of our fiscal year (this October). We will be giving it heavy consideration before we consider renewing their contract.
    I doubt that any of that will matter to a company that cares so little about their customers, but you never know.
    Thanks again for all your help. I would probably still be trying to get my replacement for the next few months if it wasn’t for your suggestions.

  • On my MacBook with Lion Safari does start, does not react immediately after trying to open it. Installing a new Safari does not help. Removing parts of Safari in the Library did not help. Where can I find and remove all components (LastSession ...)?

    How can I reset Safari with all components? On my MacBook with Lion, Safari does not start, does not react immediately after trying to open it. Installing a new Safari does not help. Removing parts of Safari in the Library does not help. Where can I find and remove all components as LastSession and TopSites?

    The only way to reinstall Safari on a Mac running v10.7 Lion is to restore OS X using OS X Recovery
    Instead of restoring OS X in order to reinstall Safari, try troubleshooting extensions.
    From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test.
    If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.
    If it's not an extensions issue, try troubleshooting third party plug-ins.
    Back to Safari > Preferences. This time select the Security tab. Deselect:  Allow plug-ins. Quit and relaunch Safari to test.
    If that made a difference, instructions for troubleshooting plugins here.
    If it's not an extension or plug-in issue, delete the cache.
    Open a Finder window. From the Finder menu bar click Go > Go to Folder
    Type or copy paste the following
    ~/Library/Caches/com.apple.Safari/Cache.db
    Click Go then move the Cache.db file to the Trash.
    Quit and relaunch Safari to test.

    I'm using a macbook pro, running snow leopard. Yesterday I got around to emptying my trash for the first time in quite awhile and was surprised by how much there seemed to be in there. Immediately after a question mark symbol appeared on all my hard disk folders. If I click on these question marks I get a message saying ' the item can't be found'.

    mpagan47 wrote: a question mark symbol appeared on all my hard disk folders.
    Not sure where these hard disk folders are located that you are referring to?  Finder, Finder tool bar, Finder side bar, Desktop, Dock? 
    More then likely they are  an alias that not longer point to the orginals,  thus the question mark.
    I would reboot.  Delete icons if an alias and just recreate by dragging from the source. Try right click (control) click to remove.

    Try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose any data by resetting, but it can cure some glitches.

  • There is always a blue screen appears after the Apple logo during the booting process. And then everything is back to normal. What is this thing? Is there something wrong with my screen or something?
