You have questions that are beyond the scope of this forum.

You have changed a systemboard and used the wrong part number. The motherboard you have used is for a computer laptop touchsmart dv8t, not a computer laptop dv8. This makes the troubleshooting your own question, because there are so many things that you have not made correctly.  If your laptop was not the touchsmart dv8t model, then there is a problem with the connector that connects the LCD screen and the motherboard. This is probably your biggest problem is.

What is the number of complete product or the name of the product from your laptop?

DV8 is a series of models which includes a portable, including version touchsmart allowed that you have installed.

    There may be something wrong with the screen of laptop computers.
    I guess that the graphics card is ok because the external screen works properly.

    But it s very interesting to know if you are using the graphics driver from Toshiba. If this isn't the case, please check if this problem also appears after installation of the graphics driver from the Toshiba driver page.

  • When I open Roxio it changes the screen resolution of 256 colors at a very low resolution b and the program will not work.

    My Roxio VHS TO DVD movie editing program has worked on my laptop Toshiba Windows 7 system before I reformatted.  Now when I open Roxio it changes the screen resolution of 256 colors at a very low resolution b and the program will not work.  When I close the program Roxio the resolution of the screen reverts back to 256 colors.  Control of program compatibility tells that it's incompatible, but the program worked on my system before I reformatted.

  • Windows 7 changes the screen resolution when video applications go full screen.

    When I have plenty of screen some video players, that the resolution of the screen on just the ordinary 1080 p 1080 p (native) that has a refresh rate of 60 hz. As soon as I exit full screen it activates again. Would be nice but when it switches the screen is no longer fits the screen and the user interface looks very grainy, the video actually looks very good. Windows Media Player 12 for this, while VLC does not, which leads me to believe its something to do with the way that Windows Media Player makes video (which I think it uses Direct x, which uses VLC OpenGL).  I have this problem on my computer and my brothers computer I customized built. The specifications are very similar, other that my computer has an Nvidia GTS 250, and has a Nvidia GTX 275.  Is there anyway to stop it from doing this?

    Intel Core i7 clocked at 2.66 Ghz

    Just in case people always have a problem with this problem, pls here's a solution that worked for me...

    I spent the last month trying to solve this problem, and "youemailme" (another thread here) had the correct solution for me! And so Simple!

    I noticed on Blogs that this problem has existed for at least Win98 is not your computer or your operating system.

    The question seems to be programs in your Menu has a different screen resolution to set startup, thereby causing the screen resolution change when you start your computer. This isn't a MicroSoft program error, but rather a question of "settings".

    With me, what worked were 2 things:

    (1) perform the 'clean boot process' as advised by many to determine which granted software was causing the problem... and then.

    (2) right click on the name of the program (as discovered in above) 'problem' in the Start Menu > properties > compatibility.  For some reason, there is an option to "run in 640 x 480 screen resolution", which has been verified.  This program was in the startup folder and the cause of the problem.  Then unchecked the resolution box. No problem.

    In my view, there are a large number of people dealing with this exact problem. I hope that this process of step 2 could solve their problems.

    (ps, just thinking about it now, you might not even bother with the 'clean boot process' but simply go through all your programs in your Start Menu and run the 2nd step explained above. Should work?)

    See you soon

    Could a right click on the PDF file > open with > choose program by default and select CD player as default PDF Viewer.

    You can do it from the control panel as well.

    This would make CD player as default PDF Viewer.

  • Portege M700 will not change the screen orientation

    I installed the driver for the webcam for the M700, and every time I install it, I get the same error message:

    "Open Webcam driver fail - please restart camera or computer."

    I reinstalled the drivers of many times, and it still does not work.

    Therefore, I tried the msconfig method, disabled all the startup process and then reactivated their.

    The webcam shows the same error message, and now the screen will not change orientation when I rotate the screen.

  • Change the screen resolution - do not show at the edge of the right hand of the document or the screen

    I do an online courses for NSW electoral office and I can't read the right side of the issues. I use Vista business and can not find the option to display, if that's what I have to edit to change the screen resolution. I have a Benq G monitor series 19-inch LCD. This happens sometimes when I go to a bank site or the Centrelink.

  • Why Event.ADDED run HGroup when you change the size of the element?


    I was wondering why my listeners Event.ADDED/REMOVED run when I change the size of an element in a HGroup... I can't understand. Both are running.

    I am writing a card game and I want to increase the size of a card in the HGroup on mouseOver. If I comment on changes in the width and height, the listener of Event.ADDED/REMOVED is not called. It runs only when I change the size of the map. The card is a custom BorderContainer component.

    Thank you


    The event.target must indicate what is to be added and removed.

    Depending on the content, I suppose it is possible that the graphics have to be recalculated to display new objects and that they be deleted and added.

  • When you change the date range, some data refresh some is not the case.

    In looking at some the report explore end-user (EU - FxM cartridge), I noticed that some data are updated based on the data and the time I selected. I noticed that the response time service level and measures processing time service level (metric in the green circle) doesn't refresh at all. I noticed the same behavior when you look at some different indicators in the report to explore end-user. Anyone encountered this?

    I think you are referring to this point of view, but I don't know how you got there from the browser of the end user:

    Looking at the Design tab in the right pane of Action and selecting the view "user end/FxM/Applications/Application Service level Layout" to inspect, it turns out that "jelly bean" service level indicators are configured to display:

    / responseTimeServiceLevel/value/latest/min

    / processingTimeServiceLevel/value/latest/min

    As the notes of Osama, the "last" value here will not change when the time interval of page is updated.

    Contrary to what he says, if this dashboard has been configured to display the "current" value, these indicators would show the last value not expired before the end of the time range of page.

    You can:

    -Open a session to demand that this configuration of the dashboard be changed in a future release, a matter of pension

    -change this system view (which will not survive an upgrade of the FxM cartridge)

    -(deep) to copy the view "User end/FxM/Applications/FxM information request" and change the copied view (which survive and upgrade). You must also change the type mapping "FxM Application result" in Applications/FxM/end user to point to your point of view, updated the.

    Kind regards
