    Tried changeing them in safe mode and in reg mode on my tv but no luck.

  • zjayzeeb Jul 21, 2009

    but it works fine in safe mode . ive taken it out and put it back and just did a system recovery that i know regret it didnt work and i lost some stuff. Could hooking it up to my tv when i was waiting on my new screen have something to do with it??? I also broke one of the locks that keep it closed the other one is still intacked ..

  • zjayzeeb Jul 21, 2009

    OK about to throw in the towel..in safe mode it doesn't give me any options to delete the monitors ive ben all over the resolutions no changes, works in safe mode but black in reg mode still . im working right now in reg mode of of the tv and i have explored the NVIDA CONTROL PANEL , it gives me lots of options to change monitors and to fix resolution's but still no luck .. i closed the lid and the light goes off. i think i caused the problem when i first hooked up to the tv when i had no screen in the notebook. When i turn it on now i get HP and then Microsoft's and then black but i can hear windows opening. You think my video card has anything to do with it??

  • zjayzeeb Jul 21, 2009

    One more thing its a pavilion dv 9700... Thanks for your help so far..

  • zjayzeeb Jul 22, 2009

    Were do i go to swich the displays?

  • zjayzeeb Jul 22, 2009

    The fn- f4 does nothing in safe mode will have to try the tv in reg mode.

  • zjayzeeb Jul 22, 2009

    The fn- f4 does nothing in safe mode so i will try to access reg mode threw the tv.

  • zjayzeeb Jul 24, 2009

    It doesnt give me that option enable VGA mode.

  • zjayzeeb Jul 24, 2009

    Tried both no luck . I don't have any other numbers or letters after dv9700..

  • zjayzeeb Jul 24, 2009

    when i said i tried both with no luck i was replying to nlink about installing the new drivers.i have already done a system recovery and that had no change . Should i go forward with your last suggestion? or do you think the registry hack would be the way to go..

  • zjayzeeb Jul 24, 2009

    lets try registry hack..

  • zjayzeeb Jul 24, 2009

    can i do it in safe mode???

  • zjayzeeb Jul 24, 2009

    I think the parallel installation is out of my league and now the screen is starting to flicker a lot in safe mode. I should of sent the laptop in from the start, they wanted $430 to repair it but i haven't worked in a long time so $200 do it yourself seem the way to go.

  • zjayzeeb Jul 24, 2009

    ya i wish i new someone that had the same pc. So format the c drive and reinstall operating system, thats not the same as system recovery or restore? how do i go about i go about it?

  • zjayzeeb Jul 26, 2009

    wow that was a lot simpler than all that other mess, im now running in reg mode but windows wants me to restart and when i did it the first time it went back to black screen , my screen in still flickering what can i do wile im still running in reg mode ?

  • zjayzeeb Jul 26, 2009

    It only works the first time then after restart goes back to black. Ive done it twice now...

  • zjayzeeb Jul 27, 2009

    Ive uninstall the driver but windows is trying to reinstall at start up . Im downloading new driver now and will try to reinstall . I don't have a recovery disc or installation cd..

  • zjayzeeb Jul 27, 2009

    well the only way it works is without the driver, i went to hp support and drivers and installed it back but no luck after restart it goes black. Now i made sure the new screen was exactly the same model as the one i took out , why would the same drivers stop it from working??

  • zjayzeeb Jul 27, 2009

    Ive done a system recovery is that the same??

I don't know what the other people have been telling you, can you start up in safe mode, then right click on your my computer, or computer. its either on desktop or in start menu.

click on manage from the right click menu.

on the computer management window, on the left side select Device manager, then on the rightside open up display adapters, right click on your display adapter and uninstall it, uninstall drivers if it asks, then restart the computer normally, is the problem solved?

    Hey

    the issue seems to be the video card drivers, when you restart in normal mode windows reinstalls the drivers. You should try the windows installation cd or recovery discs that came with the machine to start fresh.


  • Ekse Jul 26, 2009

    or you can try and find the driver software from start -> control panel - > add or remove programs / uninstall programs.

    if you get it removed it wont install the drivers, then you should look up new drivers from the makers website www.hp.com


  • Ekse Jul 27, 2009

    Alright

  • Ekse Jul 27, 2009

    Don't know, maybe the resolution or refresh rate is out of range so it can't show picture, when its without drivers its on default settings. I'd try reinstalling windows, if you don't have the discs recommend you take it to a local shop, they should do it for something like 20usd.




  • Ekse Jul 27, 2009

    No,

    a fresh install of windows, its more than just a system restore, take it to a local professional if you don't have a windows installation cd. They will check that you did everything else correctly while their at it I'm sure. we can't check that over the internet.

Why It is happening
It is happening because each and every console works on different frequencies. Since, You connected your LT to TV the autoplug and play has changed the resolution of the AVG which in turn transmits the different frequency to your television which should be very high in comparison to your LCD monitor. Now it cannot revert back to the lower freqnency because of limitation of your AVG card. Few AVG cards have this limitation that they can change easilly for higher frequencies but not towards lower frequencies. Instead of getting any display if you connect it to some other tube based monitor you will read error of out of frequency range error. Since all your options to change the AVG cards out has been locked out. You are able to get display in safe mode. because in safe mode only standard console driver is loaded which is not enhanced through your AVG card.
How to correct it.
1. You are only left with 3 options either get one more LT of same model and connect your your console output to its com and select the option of using dual console. This way the PnP will change the frequency of your AVG to earlier stage.
2. You have to reformat your root and re-install all your drivers and programmes. But select this option only if you have all the drivers available with you and take the backup of your imp files before optiong.
3. Registry hack, Meanwhile, you ponder on which option you wish to choose I know the best solution for you would be this registry hack. Through which I can disable your AVG driver via your registry. But for that I require minimum 30 minutes.
Kindly do let me know which option you have selected and as of now don't accept this as a solution or rate me or else we will not be able to communicate.

    If you have tried both with no luck then I don't suspect on your frequency any more. I suspect on your new LCD. Have you tried connecting it to other LT with same model.

    3. On the Registry menu, click Load Hive, and then open the following registry file in the original Windows installation:

      %SystemRoot%\System32\Config\System Assign it a name other than System (such as "Test") in the next dialog box (the Key Name dialog box).

      NOTE: The file must be open before the key name is changed.
    4. Go to the following registry key and note the value for Current:REG_DWORD (this selects which ControlSet00x to load when booting and is the one that needs modification):HKEY_LOCAL_MACHINE\TEST\Select
    5. Perform the following steps to disable a service:
      1. Go to the following registry key:HKEY_LOCAL_MACHINE\TEST\ControlSet00x\Services\Where x is the value of Current:REG_DWORD
      2. Change the value of Start:REG_DWORD: to 0x4.

        NOTE: Other Valid Services start options are: Automatic 0X2
        Manual 0x3
        Disabled 0x4

    6. Perform the following steps to disable a device driver:

      1. Go to the following registry key:HKEY_LOCAL_MACHINE\TEST\ControlSet00x\Services\Where x is the value of Current:REG_DWORD

  • Aruna Singh
    Aruna Singh Jul 24, 2009

    Sorry for the delay Fixya just froze my premiums for few minutes. It will happen your screen will deffinetly flicker because the frequency which is presently coming out is meant for your tv not for lcd. I suggested you to format your C drive and re-install your operating system not re-storation as the first solution. Second solution was also simple because you could have simply tested and proved your avg card and for the third option the registry hack its meant for professionals even if i try to create a batch or exe file for it it will take minimum 2 days for me to do that and a lot of pain as you can assume i've to programme everything to be done automatically which you cannot do by yourself.

Hi there

This is very much a driver issue. The display is working upon boot (the logo screens) and in Safe Mode as those modes use a generic video and monitor driver. But it isn't working in normal mode as the driver has been removed after the installation of the new monitor.

Can I ask you to boot up the laptop, and immedietely after you see the first HP logo disappear, keep on tapping the F8 key until a list of options comes up on a black screen (this is the same screen from where you accessed the Safe Mode option from). But instead of choosing Safe Mode, can you select the option called Enable VGA Mode (or similar).

After doing that, does it boot into Windows normally? You'll know if it has because you won't see the words SAFE MODE appear on the corners of your screen like they do in the actual Safe Mode.

Let me know if it gets into Windows by using the Enable VGA Mode. If it does, your screen may appear low quality. If it does, you will need to install the video card drivers. To do this, although your laptop is the DV9700, there should be a more specific model (such as DV9700T, or DV9701, etc). Please check the label on the base of the laptop for any specific model number. Pease let me know.

Best regards

    That option is usually present. It does appear the video drivers are at fault.



    You will need to enter Safe Mode as before, and install the video drivers within Safe Mode. However, you will need to download the drivers on another computer and then take the installation files to the laptop via a USB drive (for example) and the Internet will not work on the laptop in Safe Mode.



    This is the driver you need to download and install.



    If that does not fix the issue, you'll need to try this one instead as the correct driver depends on your specific model of laptop. The DV9700 could have either video adapter so you may have to try both until one fixes the issue.



    Let me know how it goes.



    Best regards

I apologize up front for suggesting this if you've already done it; pretty much all laptops have a way of switching between display types. If you had your TV hooked up you probably switched your laptop from LCD display to external display. Check the switch and see if you just left it in external mode. The reason it would work in safe mode is because the switching software driver would not have been loaded in that mode. Failing this, if the lcd still doesn't work there may be a problem with your new display. When in Safe Mode your computer is running as a plain old vanilla display with slow cycle speeds. Once you display in regular mode the display is switched to a higher frequency. This might be part of the problem.

Good luck, and I hope it is just the switch.

    Sorry for the time delay but I had to track down my copy of the manual. Press the "fn" & "f4" keys at the same time and that will allow you to switch between the internal and an external display. I truly hope that this will resolve your issue for you. If not please let me know and I can dig further.

Assuming the new display is good then you either need to reinsert the data connector again or make sure that the ground wire is properly attached. As long as the display is good or the display and laptop base were not subjected to a static shock it's just going to be your connectors.

The data connector is the plug that pushed into the connector. They can look like they are in right but not be quite right. The ground wire will just be a lug terminal and a screw that has to go to the right place as well as making good contact. Those would be the two things that will do this. So you have to take it apart again and double check everything. Annoying but won't take long and you should be running.

You should see the display do something as soon as you hit the power button. Should show the hp logo or some form of boot display. No need to wait for windows to get started.

    Ok I see that you did get a display in safe mode but not in normal. That makes a bit of difference. Sorry I must have missed that before.



    Boot into safe mode and open control panel-system-hardware-displays. Delete any entries under display. Reboot. It should now detect the display and install drivers and work.



    I think the ZD8000 actually uses the same display as a Toshiba model (can't recall which one) so windows may not be recognizing it properlly. You may have to delete the video card entry as well as the display again if that doesn't work. You just need to find out which one isn't working and windows will detect and install the new drivers when you reboot and you should be back up and running. You probably will have to delete these in safe mode then allow it to reboot into normal to make this work.



    Let me know if that gets you running.

    Dave King Jul 21, 2009

    I'm having a bit (lots) of trouble seeing comments and replies. I just noticed the broken hing or attach point. Can you check to make sure the lid switch is working? Either close the lid and look around the display to see if it goes off or if you can manually press the switch. This can be another issue that is causing the problem.



    If you are getting a display in safe mode you did your fix right. Give yourself a pat on the back as I know a lot of so called techies that can't do that ;-] So your problem is just windows acting up a bit.

    We just need to narrow down what is still wrong and you should be fine.

  • Dave King
    Dave King Jul 22, 2009

    When you use an external monitor usually the laptop detects when it is connected automatically. You can also force the display to show only one. This normally will revert back to the laptop display when you reboot.



    You can try switching it using the function key for it. Hold down the key marked "FN" and then tap "F4" That will change the display mode. There are 5 modes for your laptop. So press the function key at least 5 times to cycle through the modes. Hopefully one of them will wake up your display and you are back in business.

Dear lotaman, I have searched the world to find an exact guide for your monitor but it is impossible. Neveretheless I have found the following guides and they should be more than enough to complete the task in hand anytime.

TIP: The ZV5000 looks and is very similar to the HP DV1000 screen so I would start from there. All guides are very nicely explained.

Please remember to remove the battery before you do any work with the laptop.
