Screen went black during use.  What can be the problem?

That may be the problem if the screen turns black during use?

First of all, if you use an iPhone 4 as indicated in your profile, it cannot be updated to iOS 9.3.

Regarding the screen gone black, try a reset.

Press and hold the Home and Sleep/Wake buttons for at least ten seconds, until you see the Apple logo.

If again, the screen becomes black, it is very possible that this is a problem with the hardware for a date of the iPhone 4.

    Tells us that the problem is in the printer itself or the printer driver - because Photoshop and InDesign do not share any code to print (they don't use even the same APIs to print).

    Since yesterday I have a problem with my laptop. During the work screen turned all black and laptop stop working. I can not normally function laptop now, because every time that it stop working after a few seconds and I can't just this one will turn off.

    I tried to find something in the BIOS but it stop working too so I don't have too much time. Once I saw communicate "Media test failure", I tried to restart with a disc of recovery, but it stop reading DVD player after a few more seconds.

    I have Windows Vista, I don't think it's a virus. The time to start turning off computer talk 3-15 seconds. And if I try to run it just after closing his stoppage of work more quickly.
    Warranty service is 200 km from me then I'd be happy to get any help here :)

    I tried to take our and battery set, doesn't change anything. Sometimes without battery, I can not turn on the laptop at all (it won't happen with the battery inside).


    To me, it looks a bad hardware work because the DVD Player stops playback of the recovery disc.

    It's really hard to say what the reason for that, maybe it's a problem of the motherboard or RAM.
    The RAM you can test it with Memtest86 ([]). There, you can download an image of a bootable floppy. Download, burn to a disc and boot from it. The test runs automatically and if the RAM is faulty the program should be.

    If Memtest86 can t find a mistake, I think you need to sent the laptop to an authorized service provider. Technicians can check the mobile and Exchange defective parts. I think they'll help you as soon as possible.

  • iPhone 6 screen goes black randomly. Hard reboot solves the problem temporarily

    Hi all

    My iPhone 6 screen goes black randomly (usually during sleep) and when it happens, the fact response to touch or no sound. I know that the phone is on because I can always call another phone and it sounds on the line, but as I said the iPhone does not ring. Hard reboot (press home + power button for a while) will not solve the problem immediately after the restart, but after some time (hours or days), it goes black again and I have to do the same thing.

    No idea why this is happening? Is it a software or a hardware problem?  I'm really curious to know how to restart the phone resolves the problem.

    I am not able to take it to the bar of the kind of these days because of my busy schedule. I wonder what they need to replace when I take it to the store.

    Please, share your ideas.

    Thank you

    Sounds like a problem of software for me, especially because it forces is a troubleshooting step software, and you say that solved the problem (of least temporarily).

    However, I still think that the Genius Bar would be a good idea. They have access to diagnoses that are not accessible by the user, who can easily identify which applications or processes are causing the problem. I think that they can also do this by phone, but I rarely call support so I am not sure.

  • my computer won't read or recognize CD or DVD. What can be the problem?

    When I try to install a software, play a CD or DVD, nothing happens.  I hear a few clicks and a humming noise, but then nothing.  I have the default to auto-play.    The instructions for the software says to follow the instructions on the screen, but they never show.  Is this a driver problem, and if so, how can I solve this?


    Step 1: Please do all the same underneath if you did some before as is often total
    a process that solves the problem.

    Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
    Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
    RESTART this will refresh the default driver stack. Even if the reader does not appear to continue

    Then, work your way through these - don't forget the drive might be bad, could be a coward
    cable or slight corrosion on the contacts (usually for a laptop) and other issues.

    The CD drive or the DVD drive does not work as expected on a computer that you upgraded to
    for Windows Vista

    When you insert a CD or a DVD, Windows Vista may not recognize the disc

    CD/DVD drive does not appear in Windows Vista, or you receive this error in Windows

    Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
    ends. Remove and replace, do not just tight. For laptops, you can often clean power and
    contacts data with a pencil eraser.

    Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
    manufacturer of device to see if there is a firmware or drivers for your drive if necessary.


    Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD
    Burn and CD and DVD read). So it is not unusual for 1 or 2 operational so that other parts
    do it right.

    Did you follow the Troubleshooting Guide for the reader who still does not work? There are
    the entries in registry that the troubleshooter does not solve and those who "might" be the cause.

    Check with your Maker system and a device for the two possible firmware updates and
    the correct registry entries for your car.

    Here are the keys that I of course are those in question - for the subkeys of the CD/DVD drive
    as there will be other subkeys in these keys. Do not forget to ask specific keys involved as well as
    the parameters.


    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\0001\System\CurrentControlSet\Enum\IDE

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}


    You can probably find more info here and maybe even the exact registry for your CD/DVD settings
    drive from someone with the same model.

    CD/DVD units

    Use DevManView to locate the CD/DVD in the registry (be careful and do a prior Restore Point)
    nothing change) - find the DevManView device and then make a right click on it free in RegEdit.

    DevManView - free - an alternative to the standard Windows Device Manager, which displays all the
    devices and their properties in flat table, instead of the tree viewer

    I hope this helps.

  • Try to download firefox beta on Sony Ericsson X 10 reveals the message "the requested item is not found. What can be the problem?

    I try to download and install Firefox beta 3 for Android 2.3 on Sony Ericsson X 10. I am able to access the site of the Chamber of combustion/m well but when to download, I get the error message "not found - the requested item is not found."

    The link to download Firefox for the Android Market does not work on phones with incompatible equipment. You can check if your phone is compatible here:

    Even on some devices supported, a bug in the software of the market prevents Firefox from appearing. This may be linked to the fairly recent Android Market app update. If you go to settings/Applications/market and choose "Uninstall" you can uninstall the update and then seek out and install Firefox on the market.

    Or, if you have a compatible phone, you can download the application directly from here:

    (Note: to download the app directly to an AT & T phone, you will have to search for 'sideloading' instructions in the APK file, because AT & T disables the option to install non-market sources.)

  • What can be the problem...?

    Hi RexDoug,

    You are absolutely right... Please give me an answer...

  • BlackBerry Z30 don't switch call to the speaker using the navigation. Screen went black accept after phone call.

    I have this problem no need of me.

    While driving and use any software of navigation, such as:

    1. built in maps

    2 Waze

    3 NavFree

    If someone calls me, I can take the call. But immediately, the screen went black.

    I can't switch the call to the speakerphone. After random seconds, to switch screen might look for a second glance, and then the entire screen turned black.

    Although it is black screen, I can't do anything, including trying to drag up to close current app/call.

    Maybe it's something to do with the Navigation periodly software disables screen timeout?

    Hello, Yes,.

    Is this the same problem as described here:

    Discussion on how the screen turns black during a regular call, it is impossible, for example, to listen to a call and to have the keypad remains lit, so you can press the right numbers while dealing with an automated reception, was doing phone banking, or using any other system that relies on automated messages.

    The problem came down to how some people take their phone (especially when trying to listen to the guests and press the right button at the same time).  The solution has been to hold the phone differently.  So my question would be whether the phone is blacking out because of the very special combination of things happening in your scenario, or is it blacking out because you're online and proximity sensor of the phone thinks you're holding it to your ear (and think that when you do this, you want to have blackened keypad).
