Problem - VGA output VGA or HDMI port does not work when the connection to the input of your TV

Problem of VGA output - using an acer aspire 5520-5912 trying to connect it to the TV input - connect S-Video works well - port however VGA or HDMI does not work - 1 when I plug the VGA cable that goes to an entry of RD Gr Bl on TV, my screen goes black - as soon as I unplug the cable and press FN + F5 I get the screen back - if I restart the computer in order to have the computer to identify the external screen it will just a black screen when the priming. Troubleshooting using no external monitor is identified unless I use the S-video connection.  The Hdmi connection gives me the same result that the VGA - convenience store attempt will identify the computer screen.  OPSYS Vista. Thank you

  • HDMI port does not work

    Original title: HDMI port stopped working after the update.

    This morning my laptop did an automatic restart to install updates and now my hdmi port does not work. I tried to restore the system to a previous point, but that has not helped. I have a HP Pavilion dv6.

    I worked with a team of online crash analysis and they had update me of the BIOS. That fixed the problem and the HDMI port is now working again. For those of you who have the same problem, go to http://ftp.hp.com/pub/softpaq/sp48501-49000/sp48953.exe .

    Update your BIOS can help you too.

  • Camileo P30 does not work when the 8 GB SDHC card is inserted

    Hello
    I just got a new camcorder Camileo P30.
    I also bought a card 8 GB class SDHC 6 100 'Lexar Premium' x
    And it does not work with the card inserted.

    Here are the symptoms:
    (1) when the card is not inserted I can do everything OK - take pictures and video, use the menus, it turn on and off.
    (2) when the card is inserted, the following occurs:
    2.1) I can't take pictures or video - it does not meet the pressed buttons.
    2.2) I can't access menus.
    2.3) I can't shut off again.
    2.4) I do not identify the amount of memory is available (shows only 0 recording time remaining).
    (3) I have tried different combinations of:
    3.1) Insert the card so that the camera is turned off.
    3.2) Insert the card so that the camera is turned on
    3.3) Insert the card while the device is switched on and in one of the menus.
    (4) the camera doesn't always work if I take the card again.

    During these expriments (#3), I was sometimes able to get a record time correct left (#2.4), but still #2.1 to 2.3 # were a problem.
    At one point, I was also able to "format" the card and subsequently, he showed a record very long time available (not matching only not to the size of the map) and #2.1 to 2.3 # were still in force (i.e. I couldn't use the camera or turn it off).

    Note to work around the #2.3 I took the battery.

    I was not yet looking for updated firmware, or connect it to the PC.

    Has anyone of you has met with such a problem?
    What did you do to solve it?

    Thank you.

    Hello

    Have you tried another card SDHC?
    I m not very well what is happening here, but I recommend you another card in this camcorder.
    I m P30 not owner but I have a: 30 and the camcorder reads without problems for 16 GB SDHC card. It works perfectly.

  • VerticalAlign VBox does not work when the child has the height in %

    Hello

    I got the code like this:

    <mx:VBox id="vb1" verticalAlign="middle">
    <mx:CheckBox .../>
    <mx:VBox id="vb2" height="50%">
    ...
    </mx:VBox>
    </mx:VBox>
    

    Effect is that verticalAlignment does not work for the 1st VBox (it seems to me that it is set to the default value - 'top'). It works when I remove property "height" of the 2nd VBox (or when I change to "50%" to "50" or any other number).

    Hi Ibarim,

    verticalAlignment won't work for VBox when you have two or more children and who are direct children. When you have only a single direct children of the VBox, then it will work. Normally we use verticalAlignment = "middle" HBox and VBox. As VBox sets out its children vertically this property does not work when you have children over 1.

    You can try this

    width="200" height="50%">
    
    
    
         
    
    
    

    The above two combinations work correctly you only have immediate children... But if you see the bottom of case...

         width="200" height="50%" backgroundColor="yellow" verticalAlign="middle">                                  
    

    Now, in the case above, you can see that VBox vb2 is vertically aligned middle in the vb1 vb2 VBox is the only direct child of VBox vb1. Whereas it is now in the vb2 VBox box and VBox vb3 are not aligned vertically in the VBOx vb2 as because VBox vb2 contains now two children.

    Hope this is clear and make you understand the problem.

    Thank you

  • Satellite R830 - HDMI port does not work

    Hello

    Is there a driver for the HDMI for the Satellite R830 port?
    It is no longer connects to a TV.

    I tried different TV but still nothing.
    Also there is no HDMI in under the control panel Device Manager, should there be?

    Thank you very much for any help or advice.

    Hello
    I put t know what Windows system that you use on this laptop, but the driver HDMI isn't available from the HDMI port driver is part of the system and should be recognized automatically.

    Capacity Audio HDMI you need to install the right audio driver and should allow this in Control Panel-> sound-> playback device

    HDMI (digital out) would be not listed there, right click and choose:
    Show devices disabled, view hidden devices.

    Usually the HDMI connection isn t very delicate. Everything should run automatically.
    Connect both devices with a HDMI cable.
    Turn on the TV, then the computer.
    Now, use the exit function FN (key) video combination in order to get to the video (HDMI).

    Note: the correct HDMI channel must be selected on your TV

  • Microphone does not work when the headset is connected (Windows 7 with Realtek HD Audio).

    I am a user in advance, but this got to be one of the funniest problems ever. First, I had 2 headphones with microphone.

    1. An old helmet specified with microphone
    2. A new headphones A4Tech HS-100 with microphone that I just bought
    Problem:
    • Using the new helmet I bought, when I plug the microphone (pink jack even) it works, but also when I plug in the headphones (same headphone jack), the microphone no longer works (cannot receive all the sounds, even if it is detected clear as already plugged) and only the work of helmet.
    The most funny thing is:
    • The old headset works fine when I plug the microphone (jack Pink) and headphones (headphones) to my ASUS N81V laptop.
    • When I plug the microphone on my laptop and plug the headphones to my iphone, the microphone and the headphones work!
    • To experiment more, my laptop has a HDMI output connected to an external HDMI monitor, when I connect the microphone on my laptop, only it works, but as soon as I connect the headphones to the headphone jack on the external HDMI monitor, the microphone works again!
    Things, I tried and does not work:
    • Maximize the microphone amp
    • Separate entry made in the audio Panel
    • Ensure the microphone is not dumb anywhere
    • Install the latest drivers from the manufacturer and realtek Web sites
    I want to get both my mic and headphones works when plugged the laptop, what exactly is the problem? Any help? Thank you very much.

    I have a similar problem with my netbook a built-in microphone running Windows Starter, that's how mine to get the fix:

    Control Panel - his - recording tab - click on Configure button - set up micro - Configuration of the Microphone Wizard.

    You'll see three choices 1. Headphones Microphone 2. Table microphone 3. Others.

    All what I have to do to fix my netbook is to select the desktop instead of headphones with Microphone Microphone (it has been revived somehow).

    Android version 5.1.1

    2) press the squarre and switch to the camera application, which says now: "camera not available."
    3) slide down twice, turn off the flashlight and switch camera to the photo app, now there is no message, but the camera still does not work.

    (4) use the table to any other application, then the table to return to the camera application, which now works fine now that the lamp is off.

    If you attempt to try the above, when you are in the camera app, once you drag down twice, there is no icon to turn the flashlight.

  • V11.0.12 XI and IE11 Acrobat. Hyperlink inside the PDF does not work when the PDF file is opened with any browser.

    V11.0.12 XI and IE11 Acrobat. Hyperlink inside PDF is a blue rectangle and links to another PDF. When PDF is opened in Acrobat, the link works. When opened in any browser (IE, Firefox, Chrome) the link does not work. How can I get the link to work in browsers?

    I think it is a bug. I uninstalled Acrobat and reinstalled Acrobat v11.0.0. I tried the link and it works properly. Then, I installed each both updated and tested the hyperlink. Update 1-10, that the link works. However, when the 11.0.11 update is installed, the "Go to a page in another document" hyperlink stops working in browsers. V11.0.12 installation does not solve the problem. If I uninstall Acrobat and install v11.0.0 with updated v11.0.10, everything works fine.

  • Music app does not work when the screen is closed!

    Android6.0.1

    Compact Z5.

    When I listen to the music in the music of sony and closed the screen app, music will play a minute and stop, even when I turn the offshore endurance and add it to the white list, but it doesn't work.

    Other applications that can play music also encounter this problem. Some applications of music need wifi, they cannot work when the screen is too closed.

    What can I do about it?

    I think also ultra endurance disables many apps, so my guess is that you have a 3rd party app that close somehow your applications when the phone goes to sleep.
