HP Elitebook 8470w/display screen does not

Hello

We have a 8470w (XT908UT) computer laptop Elitebook with the screen on the laptop does not.

Do us get the display on an external monitor but not on the laptop to display itself.

Check the display settings of the control panel and Device Manager, the external screen is present while the computer screen is not.

We have unplugged every unnecessary internal element for display (same HDD, keyboard and trackpad)), problem persists

We changed 2 motherboards, 2 screens and card 1 gfx. Still the same problem persists.

Can anyone help?

Thanks in advance.

After some research in the service manual and hp partsurfer.

It seems that we have received a gfx NVIDIA instead of one card

Gfx ATI card. The service manual says its compatible but not. Partsufer mentions only the gfx ATI card when the laptop

PartNumber is submitted.

the display is now correct.

hope this helps future display troubleshooting.

    Hi, guys! I have a problem. I'm not able to use the screen on my Lenovo T60 1952 - CTO (1952-WJ3), Intel 945, Windows XP 32-bit. I tried everything I installed the correct video driver Intel, installed Hotkey drivers on the Lenovo support site. I see WE screen in "adding / removing" programs, but it simply doesn't. I can use future key like volume control, adjust the brightness, but I don't see anything on the screen - there is no "Fn" icon on the system tray. In the Task Manager, I see TPONSCR.exe or TPOSDSVC.exe. There is also no process called "On screen display" in services.msc. What could be the problem. I used and Lenovo update tool and installed everything, but still nothing

  • Double click on the ios10 lock screen does not display Apple pay even if it is enabled in the settings

    Double click on the ios10 lock screen does not display Apple pay even if it is enabled in the settings.

    Hello JPMain,

    Thank you for using communities of Apple Support. I understand Apple pay is not an option when the double click the Home button. I know access pay Apple for a locked screen can do so useful everyday. I'm happy to help you to get this resolved with you.

    I recommend first restart your iPhone. This can solve many unexpected behaviours. Follow the steps below if necessary.

    1. Press and hold the sleep/wake button until the Red slider appears.
    2. Drag the slider to turn off your device completely off.
    3. Once the device turns off, press and hold the sleep/wake button again until you see the Apple logo.

    Restart your iPhone, iPad or iPod touch

    If the problem persists, the next option would be to reset all settings. It takes all the defaults, including passwords and Wi - Fi networks, alerts, notifications, brightness, wallpaper and sounds. This will also remove your cards Pay of Apple. Even if no content is lost with this step, it is always a good idea to back up first. If you do not have a recent backup, use the following link for assistance if necessary.

    The backup of your iPhone, iPad and iPod touch

    Once you have correctly saved, reset all settings in settings > general > reset > reset all settings.

    Have a great day!

    I accepted the last update. Now, I can not display to the right of the main Itunes store, where top songs, etc would be. As the screen does not. Only on the HOMEPAGE of ITUNES STORE! Help! I've tried everything. Google it. Searched through itunes, etc. It MUST be a bug, because it started right after I accepted the 12.3.3 update on my laptop running Windows 7 32.

    I count on the part of the main screen, which is not. Its strange. PLEASE HELP ME! In addition to the main page of the Itunes Store, everything else works fine as before. Music from my library work screens, etc.

    I also have exactly the same problem since the last update. Tried to find a way to solve the problem but no luck. Someone please help!

  • Satellite M30X-111 screen does not display anything but the external monitor works

    My laptop just screen does not display anything (like when the computer is turned off), but when I connect the external monitor, then the desktop is displayed on this screen. I tried to recover the laptop using the recovery disk and it worked again, but today, it stopped working again.

    Again, I must plug the external monitor, and after I tried to restart, I continue to pressing F8 but the startup mode is not come, the noise of when you press a button for too long beeps, however, the monitor of the laptop working again.

    How can I solve this problem?

    What do you do? You want to recover the laptop?
    If Yes, you n press any F8 but you will need to boot from the recovery CD by pressing the C key immediately after starting the laptop.

    But this question seems that you have accidentally switched to external display.
    I recommend checking the Fn + F5 option. This combination allow you to switch between the display and the external monitor.

  • iPhone SE: rotation of the home screen does not work

    Hi guys,.

    I already looked for answers to this problem in discussions, but I couldn't find anything that solves the problem. Here's the situation:

    -brand new SE iPhone: he got yesterday and just imported my contacts, changed some settings and installed a few applications... that's all.

    -Home screen does not turn in landscape mode (my previous blackberry contact made it by default, so I'm used to doing all that on the phone horizontally keep and wasn't expecting such a problem with iPhone); rotation does not also happen in the app store. However, it runs perfectly landscape when you use applications (Calculator, messages, etc.).

    -J' tried the solutions suggested by other users in different threads:

    (1) checked the lock on the gray screen (it was off). tried to turn it on and then again on the way to see if the rotation is enabled without success.

    (2) looked in ' settings/display and brightness' to see if "zoom mode" has been activated to move it off but discovered that the iPhone SE (or his version of the iOS) has no "zoom mode" option in this Panel... no problem, but no solution: /.

    (3) I think that try a reset should not be necessary, that the phone is brand new and it behaved like that the first time I have it turned on (I reason?).

    (4) I read that some versions of the iPhone (for example 6) do not have the "home screen rotation" function (which, to me, seems completely absurd) and, supposedly, you can use the phone in portrait mode, while the 6s for a reason any the available option: the specs should be similar to the 6s, anyone know (for sure) if the home screen rotation is supported on the self?

    Thank you all in advance... I hope that someone will come up with a solution because I know, it seems a stupid thing, but for me, it's terribly boring.

    the plug should be similar to the 6s, anyone know (for sure) if the home screen rotation is supported on the self?

    To my knowledge, no.

  • Qosmio DX730 and Win8 - touch screen does not work

    Hello

    My wife's parents bought a Toshiba Qosmio DX730 (model PQQ11A). They have recently upgraded to Windows 8 and the touch screen does not work now.

    The problem is lack of drivers (the monitor driver reports as a generic PnP monitor).

    I have went on the Toshiba site and selected downloads driver for the appropriate model and installed a number of drivers, including recommended NVidia display drivers. There is no drivers on the site that seem to install support for Toshiba touchscreen.

    Are there no drivers available for this model Windows 8? If not, is there another solution? If Yes, where can I find them. Any help very appreciated because they have nice and bought computer Windows 8 so they could use the touch functions.

    Thank you.

    Hello

    On the page of the Toshiba UE driver you can find drivers for Win 8.
    As far as I know that you will install the Toshiba display driver for the touch function works correctly.

    I found this driver.

  • Screen does not work on Satellite L775-10F

    I turn on the computer and the screen does not work. Everything seems fine but the screen is all black.

    Nothings happening. I tried turning market and its still does not.
    I also tried to connect to my TV with an hdmi cable.

    What should I do?

    Connect it to the TV and wait until Windows 7 is fully loaded (you will hear sound Win) than trying to use FN + F5 several times. It may happen on the TV Office. Be sure you use the right settings on the TV (HDMI port must be enabled on the right).

    F nothing helps I presume the display can be defective then contact the closest service Toshiba and let them check your laptop.

  • Portege Z930 - display driver does not work properly

    Hello

    We have a Portege Z930 with Windows 7 64 bit in use where the Intel display driver seem to work fine.

    First problem is the slow presentation on screen - if we open a (simple JPG) photo and move the window, the frame window break during the move and showed very weird.

    Then, we have installed a U3.0 dynadock docking for the use of two external displays more. This method works even worse. To the docking station, we used the driver from the CD supplied in the delivery and connect to a USB 3.0 connector.

    On starting switching on 2 screens instead of internally for computer laptop screen does not work - and we use workaround of using an extended desktop on all 3 displays (2 external and internal display for laptop as the third).

    In Internet Explorer, it should turn off GPU Rendering and use Software Rendering rather because otherwise, we observed critical irregularities on the external screens (with 2 Windows Open the screen froze or could not display Windows Mobile). However the display isn't satisfactioning.

    We have tried 3 different versions of the recommended Driver Intel which is also offered by Toshiba to download; We loaded it is there and also 2 versions more (a more recent, one older) Intel directly.

    So, how can we get this working properly?

    Thanks in advance and best regards,
    N. Cochems

    More importantly. Make sure you have Service Pack 1 installed Win7. New laptops have problems running in win7 RTM (without service pack).

    It seems that Windows uses the standard VGA driver instead of the Intel driver. Uninstall all display drivers from Control Panel-> programs and features and then go to the Toshiba website and install the utility Intel Chipset then the Intel display driver, then go to DisplayLink.com and install the latest DisplayLink driver for the dynadock. The new software v7.xx DisplayLink driver fixes several issues found in v6.xx drivers.

    Verify that the Intel drivers are installed properly in Device Manager.

  • Satellite A60-122: screen does not work - rest black

    Hello!!

    Can someone help me please on a screen problem? I have a Toshiba Satellite A60-122 and when I turn it on the screen does not work. It remains black as if the power of the laptop was turned off. I tried to connect the laptop to an external monitor, but it still does not work. I have no more ideas of what can do to make it work.

    I already told to format the pc with the cd of restoration but without an image, it is impossible to do anything...
    Thank you

    Isabel

    Hello Isabel

    I'm not an expert, but if there is no image on LCD internal display and the external monitor, I assume that there is a problem with the graphics card. I think you should contact the customer Service of your country partner and let check the device.

    I also hope that the warranty is still valid and if something needs to be replaced they will do it for free.

    Bye and let us know if you have more information about it.
