Why does my monitors light dim on one side?

my monitor is darker on the left side......sometimes flickers a bit....... any suggestions on what to do?

Contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.  Might also apply to new machines the first 90 days. BTW, the AppleCare Protection Plan's the best insurance policy available for desktop machines. Get it if you don't have it before contacting Apple.

  • Why does Batch Monitor hang

    Why does batch monitor seem to hang.
    It says it's processing, but no of the the times or the percentages done,
    Seem to move.
    Sometimes I can pause the task then resume and it works.
    Sometimes not.
    Sometimes I have to start another batch rolling, pause the problem
    one and then resume it after the other batch is done.

    Same is happening here.
    I've tried the Pro-Apps update and trashed the files as instructed but Compressor's Batch Monitor quits unexpectedly.
    Ahhh this is really frustrating, am on a tight deadline and really need it to work.
    Weird thing is that once its quit its seems to still process the files, which is a worry as I can't trust the quality of what its doing. My client is going to kill me!
    Apple sort your "Pro" apps out, they need to be reliable!

  • Why does my keyboard lighting stay on its lowest setting?

    why does my keyboard lighting stay on its lowest setting?

    Negative, that was the first thing I tried. I've also reset the SMC, nothing.
    I can see a little bit of light ubder the keys (white light, not blue) when I dim my screen to the lowest setting, but when I press F6 to strenghten the light, it does not get any brighter.

    Actually, if the setting is correct in Sys Prefs, and it's dark enough, and the lights still don't work, try an SMC Reset (not a PRAM Reset): http://support.apple.com/kb/HT3964.

  • Why does the amber light blink when the wifi is working

    Why does the amber light blink on the airport extreme when the wifi seems to be working?

    The AirPort Extreme has a message for you. To see it, open AirPort Utility and click directly on the amber dot.
    What does the message say?

  • Dual Monitor + Lights Dim/Lights Out

    Forgive me if this has already been discussed:
    I have 3 monitors, two high resolution main monitors and a 21" Cintiq.
    (My normal mode is to open PS on the Cintiq, put all menus on one of the high res monitors and use the other high res monitor for a larger view of the edits that are being made on the Cintiq.)
    Lightroom is single monitor, and I can live with that for now but there is one feature - Lights Dim mode and Lights Out mode - that just plain does not work if I want to use the other monitors to open any other application. The monitors without Lightroom are also dimmed or blacked out, so the other application becomes useless.
    Here's an example: If I'm running Lightroom on monitor 1 while also viewing one of the Luminous Landscape Lightroom Tutorials on monitor 2 I can't use the Lights Dim mode or Lights Out mode - it dims or blacks the video. Ouch! (Maybe there's a preference setting I haven't found yet?)

    I don't think this is a bug. The whole point of the "Lights Out" feature is
    to minimize and remove distractions while you are evaluating your images for
    color, color casts and exposure. So, I am going to guess that Adobe feels
    the other screens to also be a distraction. They could be right. However,
    given that I figure a good number of people may not feel that way
    (sometimes, not all of the time I am that way. Three monitors here by the
    way) needs to add a preference setting that lets you decide which monitors
    go "Lights Out" similar to the slide show playback monitor selection option.

  • Why does the back light on my Tour keep going in and out?

    All of a sudden (over the 4 or 5 days) my battery is draining very quickly.  I take my phone off the charger at 8:30am and by the time I am driving home from work @ 5:00pm the battery is completely dead.
    I also just noticed that there is something wrong with the back light dimming.
    You know how if you don't touch your phone for a long period of time (mine automatically locks) then the back light dims slowly to black.  My phone doesn't light up again until you touch a button or do something to the phone.
    Since I have been having battery problems I noticed that after prolonged none use my phone dims to black and then immediately lights back up again on its own. And it continuously does this all day long, which is why I think it is killing my battery.
    Anyone know why this is happening?  I tried turning the phone off for awhile and then back on....nothing seems to help.
    Help!
    Solved!

  • HT201401 Lighting cable only one side can be charged?

    Why my lighting cable can be use for data transfer in both side
    But only can be charged the power in one side only?
    It is my problem or?
    Design by apple?

    I tried that first.  It didn't get the gunk that was in the bottom of the port.  The toothpick popped it right out in one piece.  Took almost no pressure at all.  I was worried that I would hurt something with the toothpick so I gently inserted it at one side and then slide it to the other side of the connector sorting of feeling it out.  It came out with a big block of gunk from the bottom of the connector.  I was just probing the connector to see if the toothpick would fit.  I really hadn't made any effort to clean anything yet.  I I was amazed at how much gunk there was.  I keep my phone really clean but I guess my pockets are another story...

  • Why does Logic only initially open on one of my monitor screens despite launching it from the other screen's dock?

    I have a second monitor hooked up to my iMac.  How come when I launch Logic from the second screen's dock, it only ever launches in the primary iMac screen?  I thought Mavericks was all about screen independence . . .
    I'm thinking about buying a 27" second monitor to replace my smaller one so that I have extra screen real estate for Logic, but if I can't launch Logic into it by default, I am having second thoughts. 
    Any suggestions?  Thank you!

  • Why does Server Monitor not work with non-Xserves?

    Does anyone know why Server Monitor does not work with non-Xserve computers? We acquired a Power Mac for a server, based on there being no apparent difference except for the obvious. Turns out there are some differences after all.
    Do Power Macs lack some hardware components or is this just a software thing?

    God question, unfortunitly I dont have the answer but I would also like to know why the software only works for X-Serve....Is there any 3rd Party Software that is similar to "Server Monitor"?
    Thanks

  • Why does Activity Monitor show traffic to my external drive?

    Because one of my email accounts was hacked a couple of months ago (from my provider's end, I'm convinced), I have been monitoring network usage on my iMac using Activity Monitor. Yesterday, I noticed almost continuous use, altho "spiky".  The spikes were very regular and high and just kept going on and on.  I shut down all my apps (including mail, browser, etc.) except Photoshop.  Spikes still there.  Pulled out the Ethernet cord.  Spikes still there.  Shut down blue tooth, wi-fi - spikes still there.  Overnight, I shut down my computer.  This a.m. when I powered up, still spikes.  I noticed Time Machine was running.  Stopped it, and spikes stopped.  I have my back up on a separate external hard drive.  Why in the world would Activity Monitor show this as "network activity"?  Is there any way I can use settings that would show only "real" network activity, from outside my wi-fi, blue-tooth, and external drives? Spiky right now (can't get screen shot to upload), but more irregular. Have browser, email,and others open. Time Machine not running.
    Maybe there's some other app that would help me watch my network usage in the way I would like. Please recommend.   Thx!

  • WHY DOES BATCH MONITOR FAIL EVERY TIME SINCE LATEST OSX UPDATE?

    I cannot get anything out of FCP5 into compressor without BM saying failed as server application quit unexpectedly!!!!????
    This is supposed to be a commercial professional set of tools and so much of the time they just do not work!!!
    Why is the BBC giving up Avid etc and moving down to FCP and compressor etc??
    Sorry for the moan, I am at the point of throwing my G5away in frustration at this point.

  • Why does it let me erase only one cookie at a time, or all cookies at once, and not let me select multiple cookies that I want to delete?

    Do you not realize that there are HUNDREDS of cookies in the Cookie Jar? I want to save SOME of them (banks, stores, Facebook, etc.) but get rid of the rest. Why have you made it so that I can't click & drag (or otherwise select) multiple cookies for deletion? You're going to make me delete them one at a time? What could possibly be the reasoning for such a decision? Or is it an oversight?

  • Why does 2 Airport Expresses connects to one another instead of connecting to the primary Airport Extreme For internet Connectivity ?

    I have Netgear DG834G router only for dsl connectivity wifi connectivity to that router is off. i have connected netgear that provides adsl connectivity to the  (Shakeel's Airport Extreme) Airport Extreme dual band Wireless N 5th generation via cat 5 cable so airport extreme is the main wifi device through which i get wifi signals at my home. now our house is big and i have installed the adsl netgear modem and airport extreme router at the same place in my room in the upper story but the signals are weak even in the upper story at the other end of the house so i have installed the new airport express dual band wireless N in the upper story (Kafeel's airport express) and it is connected to the primary airport extreme  (Shakeel's Airport Extreme) wireless router in range extention mode it repeats the same ssid. Our ground floor has another airport express dual band wireless N the new one ( Lounge's airport express) signal was weak there so i installed another airport express (Lounge's Airport Express) their and configured it to extend the range of primary router airport extreme  (Shakeel's Airport Extreme) in the upperstory with the same ssid. Now the problem i am facing that sometimes lounge's airport express connects to kafeel's airport express instead of connecting to the airport extreme and the signals in lounge are weak because all the devices are connected to kafeels airport express and does not connect to lounge air port express. but when lounge airport express is connected to primary router airport extreme then everything works fine devices connect to lounge airport express and signals are full. i have took pictures of the problem i am facing you will understand better by having a look at it. In normal working setup both the airport expresses are connected to airport extreme which is shown in this picture
    The second picture shows when lounge airport express is connected to kafeels airport express and not the airport extreme (Shakeel's Airport Extreme) this is the problem.
    isnt there a way to correct this so that they dont connect with each other and connect to the airport extreme ?

    Lounge's AirPort Express must be located signficantly closer to Shakeel's AirPort Extreme than it is to Kafeel's AirPort Express, and there must be fewer obstructions in the signal path than the other possible connection.
    The reason is that if you want Lounge's AirPort Express to connect to Shakeel's AirPort Extreme, it must receive a significantly stronger wireless signal from Shakeel's AirPort Extreme than it does from Kafeel's AirPort Express.

  • Why does the green light stay on at the top of my screen where pictures are taken?

    MacBook Pro, OSX 10.9.2  - at the top of the frame of the screen a green light stays on - I think this is the camera.  Is there a way to shut if off?

    This procedure may show which program is using the camera. It makes no changes, and therefore will not, in itself, solve your problem. It will only work while the green LED is on. The instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
    Please triple-click anywhere in the line below on this page to select it:
    sudo lsof -Fc +D /L*/Cor*/*/*/AppleCamera.plugin | sed '2!d;s/^.//' | pbcopy
    Copy the selected text to the Clipboard by pressing the key combination command-C.
    Launch the built-in Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting. You'll be prompted for your login password. Nothing will be displayed when you type it. Type carefully and then press return. If you don’t have a login password, you’ll need to set one before you can run the command. You may get a one-time warning to be careful. Confirm. You don't need to post the warning.
    If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Log in as one and start over.
