20" iMac screen gets very light at the bottom.

I just got a new 20" iMac and the screen appears to get lighter and washed out towards the bottom half of the screen. So bad that for example in the itunes library it is supposed to alternate from blue to white, but at the bottom of the screen it looks completely white. Is my screen defective or is this a common thing?

Both. My 20" iMac at work has the same problem. It is common on the ALU 20" iMacs and yes I would say it's defective. Apple may not agree though.

  • How do you fix an ipod that has a black screen and it turns on but when it turns on the screen gets a lighter black but you still can't see the apps or anything?

    How do you fix an ipod that has a black screen and it turns on but when it turns on the screen gets a lighter black but you still can't see the apps or anything?

    Try:
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Restore from backup. See:                                 
    iOS: How to back up                                                                
    - Restore to factory settings/new iOS device.
    If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
      Apple Retail Store - Genius Bar              
    Apple will exchange your iPod for a refurbished one for this price. They do not fix yours.

They have fixed it and aglined it according to them. I dont feel that that could be the reason. I have used it for half a yr already now then its un aglinment appears?

  • My iMac is getting very slow. What can be done?

    My iMac is getting very slow opening Safari or Word, even slower opening iPhoto. I have an anti virus and I have deleted all cookies, emptied the cache ...
    What can I do to regain the normal speed? Thanks for your tips.

    Hello and Welcome back to Apple Discussions. 
    One thing many users overlook is maintaining at least 15% of your HDD space free to allow correct operation of the iMac. Back-up data to CD/DVDs and delete large files until you have at least 15% free.
    You could also consider a RAM upgrade if you are running more intensive tasks than previously - 256Mb isn't much, and not is an extra 256Mb.
    In the extreme, and something I might do every 12 months or so, is to do a complete back-up of all important data and then erase everything and re-install a fresh OS.

  • When uploading videos to iWeb, the video screen gets cut off at the top. It only happens in Firefox, but not in Safari.

    When uploading videos to iWeb, the video screen gets cut off at the top. It only happens in Firefox, but not in Safari. Has anybody else had this problem?

    I'm using pure HTML5 for mobile websites although you need to provide an OGG file for Firefox. See the movie page on this site...
    http://mobile.ezmacwebdesign.com/
    If you don't have an iPhone, grab the browser handle and drag it to the left to reduce the width to see how it responds to mobile devices' fixed width browsers .
    This will play in all modern browsers and on mobile devices. You can use QuickTime Pro for the OGG or OGV conversion or get the freeware Miro Video Converter...
    http://www.iwebformusicians.com/Website-Movie-Video/Easy-Movie-Player.html
    If you only want to upload an MP4, you can use a flash fallback player and this will cover Firefox and those geriatrics that still use older versions of Internet Explorer....
    http://www.iwebformusicians.com/Website-Movie-Video/Flow-Player.html
    http://www.iwebformusicians.com/Website-Movie-Video/Fallback-To-Flash.html
    http://www.iwebformusicians.com/Website-Movie-Video/JW-Media-Player.html
    If you use any of the four fallback players above, take advantage of the fact that you can add a poster image and stop the video file from preloading. This makes for a faster page download time.
    You can also achieve this using HTML5 by adding preload="none" and poster="URL to the poster image" into the code shown on this page...

  • The green PHONE icon has dropped from the bottom of the home screen and isn't among the icons that I have installed.  I can get to it by searching but how do I get it back on the bottom of the home screen?

  • Call bar is now vertical on the right side of screen. How do I get it back on the bottom?

    Call bar is now vertical on the right side of screen. How do I get it back on the bottom? I've tried rebooting and changing screens but it won't change. I can't find a setting for that call bar.

        This isn't a native setting that I can find Relsea. Did you download an application that maybe has this function? Any luck if you reboot the phone by pulling out the battery?
    Please let us know what happens next. 
    Thanks,

    Not unless you've got accidental damage cover on it with Apple and I don't think that's even covered with Applecare - if you have that then check with them directly.
    Otherwise you may need to see if you can claim for it under your house contents insurance.

  • Since I have installed iOS 4.3.3 on my 3GS it gets very warm and the accu gets empty in 2-3 hours!

    Since I have installed iOS 4.3.3 on my 3GS it gets very warm and the accu gets empty in 2-3 hours!
    What can I do?

    Find the app that is continuously trying to send data and failing.
    Have you rebooted (reset) the phone? If that does not resolve the problem there are a number of diagnostics that you can try. A search of the forum for "battery problem" should be rewarding. You don't need to include the version in the search, as this can happen with any version.

  • HT1776 Hi, my iMac screen goes to sleep but the fan stays on 24hrs and never stops?

    Hi, my iMac screen goes to sleep but the fan stays on 24hrs and never stops? You can hear it running all night.
    Appreciate any advice.I'm using Lion. Many problems started since using Lion!

    The temps are a bit higher than I'd expect under normal circumstances, and too high while playing games, but what is the room temp where it is?
    I def. think its a temp thing now. but why does it only raise when im playing games or watching videos online?
    Games tipically press the CPU, Video Card, RAM, and everything else much harder than most apps.
    It may be a Fan not working properly, or just dust buildup.
    Boot off your Install Disk while holding down the *d key*, (not c key), then run the extended Apple Hardware Test. Some disks require you to use the Option key at bootup to select AHT. Some models have a separate AHT CD.
    Report any errors it finds.

  • When I double click my IPAD screen there are apps at the bottom. How can I remove them?

    When I double click my IPAD screen I have apps at the bottom how can I remove them?

    If you are running iOS 6 or iOS 5, those apps are the recently used apps in the recents tray. You don't need to remove then from there, but if you want to do so, you have to close them. You do that by holding down on one of the app icons until they all wiggle, then tap the red minus sign to close the app. Do that to every app that you want to close. Tap the home button when you are done.

    Do a malware check with a few malware scan programs.
