Replacement screen does not not on the DV7 6c66nr

Hello

My two year old pulled our laptop on the table. The screen began to show strange colors, glitter and is inconsistent. When the connection to external monitor of the image is very good, so I decided to buy a replacement screen. By the back of the original lcd screen replacement part number is 666396-001.

I installed the new lcd. When the laptop start led turns on but there is no picture displayed on the screen. After a lot of research and trial and error, I decided that the screen (an LG) replacement was defective. The screen went back and bought another from a different source.  Same result, led lights but no picture.

If I reinstall the damaged original screen image is visible even though distorted.  Once again, external video displays correctly. This leads me to believe that the GPU and the cable are intact.  Apparently, I ordered the correct replacement part based on the number and specifications of the screen.

So what don't understand me?

Thanks in advance for your ideas.

Hey @Kreeper ,

Thank you for the additional information if this next screen does not resolve the problem you. I would like to replace the display cable Kit 665594-001, because that could be your problem all along.

Thank you.

  • Welcome screen does not update the recent list

    For a while, starting VBAI 2010, list "Recent Inspections", paragraph "Configuration control" was not being updated forcing me to use the browse option.  I found the list in the Builder.ini Vision and modified, i.e., lightened in a bit, and while my modification is displayed, VBAI does not refresh the list to display the most recent inspection configured when I close the said inspection.  Any ideas on how to "reset" from the home screen?

    Thank you

    Eric

    Well well apparently edition Vision Builder.ni did the trick after all, but only after I rebooted my workstation... to my delight, my home screen is now updated again.

  • installation screen does not recognize the mouse/keyboard

    Hello
    Passage of the Pro x 86 to x 64. I do not have a disk original as a burnt image, which seems to me to be recent. I got the link for him to store chat session windows today. Keyboard and wireless mouse work fine in the bios. When it is at the first Setup screen (where it asks for the language, country, etc) there is no cursor or keyboard response, so I can't start the installation. I have ONLY usb 3.0 on this build. X 86 installed fine. Any recommendations? I tried to unplug all other usb devices and tried UN / reconnect the bluetooth receiver. Nothing seems to help.

    Another couple of things you can try is:

    (1) check your BIOS for USB, mouse, wirelesss options settings.

    (2) move the transmitter to a different USB port USB wireless until you find one that works.

    (I suggest this because 2 of my ports were dead until I could insstall Windows, then the pilot, but worked at least 2 other ports).

    If I comment the code between two - and - image changes as appropriate.

    Your problem is that you use a blocking operation and the Blackberry is never really painted screen.

    There are 2 possible solutions:

    (1) the blocking operation thread. This means that spawn a real thread to use UIApplication.invokeLater () instead.

    (2) paint before calling your blocking with the force operation: Ui.getUiEngine () .repaint (); It means the battery display to repaint and your screen will be permanently shown.

  • Pavilion15-p018nz: Windows logon screen does not display the symbol of 'the eye' to reveal a password and the right arrow (input)

    Which connection to Windows 8.1 the eye symbol and the symbol of the arrow to the right were posted up to that (I think so) after an automatic update of Windows. As I was intending to migrate to Windows 10 I na not invest a lot of research on this problem. Now, after the migration successful Windows 10 Home the problem still exists. After typing the password I can't check it out because the eye symbol is still missing and I have to press 'Enter' because of the clickable right arrow missing for the opening. All this happens with a Microsoft online account. I created an account local and with that, the symbol of the eye, but not the right arrow reappeared. Thanks a lot for help.

    Hi there @CKURT

    Welcome to the Forums of HP Support! It's a good place to find the help you need, so many other users, the HP experts and other members of the support staff. I understand that you want to activate the icon reveal password for your system. I'm happy to help you.

    It depends really on what version of the operating system you are running, because this kind of thing is normally controlled by using the Group Policy Editor. This tool is not a part of a home edition, you need the Pro version or later version for that.

    Assuming that you do not have a pro edition or higher, then it can be a help to you:

    Unfortunately, the version of Windows 10 I installed next to me is that the home edition as well, so I can't access to this, to check, so let me know if it works for you.

  • The screen does not match the screen size

    Hi all, any help here would be greatly appreciated.

    I have an Acer S240HL monitor I was using with my Acer PC without any problem. However, the hard drive on my PC packed and so I just bought a new ASUS Tower unit. When I plugged in the Acer monitor in the Tower there is a black area around the outside of the screen - about an inch thick. Is there a reason why this would happen/all I can do to fix this?

    Thank you very much

    You must set the scale of your graphics card to display is the size of the screen.

    You need to open Device Manager > expand display adapter > check the graphics card name.

    Here you'll find the request of your graphics card.

    For example, if your computer has an ATI video card, you will find the ATI Catalyst Control Center App for adjusting the settings of the graphics card.
    In the ATI Catalyst Control Center, click on the graph at the top left, and then select Desktops & displays.

    On the desktop computers & displays screen, right-click on the display 1 on the lower left corner of the screen, and then click Configure.
    On the screen of the deep venous thrombosis , click the scale tab, and then move the slider to 0%.
