  • Using the Cyclops speed camera app, the sound on my iPhone 4s switches off after a few minutes. Any ideas?

    when using the Cyclops speed camera app the sound on my iPhone 4s switches off after a short while. If I close the app and reopen it, there's still no sound. If I restar the phone and open Cyclops I get sound "welcome to Cyclops" or whatever the greeting is. Has anyone got any ideas?

    I've taken several Express devices apart in the past to experiment with them. The internal components warm up quite a bit in the first 10-15 seconds. They continue to heat up after this.  It takes 3-4 minutes or so before the heat transfers to the outer case for dissipation.
    Nothing is certain, but I'm 95% sure that this is your issue.  But, trying to find a microscopic break in a circuit board trace is, as I mentioned, a real longshot. If you have the time and have done things like this before, it might be worth a shot.
    I guess the bottom line is that even if this is not the issue, the device will still need to be replaced since Apple does not offer repairs. There are no software or firmware fixes for somthing like this.

  • I'm getting kernel panics each day as I shut down, the message of restarting by holding down the power button appears on the screen - it began about a month ago and. Do you have any ideas of how to solve the problem?

    I'm getting kernel panics each day as I shut down, the message of restarting by holding down the power button appears on the screen - it began about a month ago and. Do you have any ideas of how to solve the problem? I've copied the logs that I found for each kernel panic that still have the message logged. Please help if you can, I have read some of the other comments and perhaps it has something to do with my anti-virus software being on at start up. I have copied the log here. Any advice will be welcome.

    Immediate suspects are the additions you added to you rsystem that installed kexts (drivers).  From above,
    com.intego.iokit.VBX6NKE            1
    com.intego.iokit.BehavioralKext            1
    com.intego.kext.VirusBarrier.AppBarrierKPI            10.6.8
    com.intego.kext.VirusBarrierKPI            10.6.8
    com.globaldelight.driver.BoomDevice            1.1
    com.huawei.driver.HuaweiDataCardACMData            4.2
    Two experiments you can try.
    1.  Boot in safe mode and see if you can shut down normally.  All thise additions won't be running in safe mode so this test would indicate it is one of them causing the problem.
    2. Uninstall all the intego VirusBarrier stuff.  That's my first guess and the troublemaker.

  • The air port on my imac went off and i can not get it to work

    my air port on the imac weny off and i can not get it to work now

    Apple used to use airport name for everything.. is this the internal wireless card?? Or external airport router?
    If it is the internal wireless card, is it still listed in system profile.. and do a hardware test with your original CD.
    See http://support.apple.com/kb/ht1509
    The problems with Mavericks are very great.. if you upgrade installed anything can happen.. a common feature is the internal wireless card fails to work.
    Give details and we can figure it out.
    Here is discussion about the same thing as I think has happened to your imac in macbook.

  • The time on my iphone 5C is constantly changing, regardless of me setting the correct time manually or automatically, all iOS is up to date and phone is not damaged, any ideas?

    The time will stay correct for an hour or so, then jump backwards for no reason. I have tried setting the time manually and automatically and still get the same problem, and have tried with wifi on and off and it still does it. All my software is up to date and tried contacting EE who said to ask Apple. Phone is about 11 months old and have had no previous problems.

    Hi jennehbear,
    Thank you for using Apple Support Communities.
    Your time jumping backwards an hour sounds like an issue with the time zone. Take a look at this article to troubleshoot the issue.
