Satellite L - LCD monitor flashing black after desktop management

My LCD monitor started flashing black at startup. It is not if I sign out and then sign back in, only at startup. Can I open a session, the office charge and everything seems normal, then after about 7 seconds, everything goes black, then quickly, the bar tasks appears then disappears and then the desktop becomes visible again momentarily but turns black again. He quickly repeated it two or three times then starts normally.

Everything seems to work fine otherwise. I disabled my antivirus, so it would not start but that did not help. I did a registry clean up lately so I've restored everything back to well before it began and that has not helped either. I did a lot of installation and uninstallation of software recent but is unable to identify anything that might have caused it. This computer is about 2 years old. I have Vista 32-bit, service pack 2.

Someone at - he never seen this before or have any ideas what might be the culprit? Appreciate very much all the advice.

Hello

I doubt that this problem has something to do with the software or some registry keys. I think that it s unwanted material.

It would be interesting to know if you notice the same problem on an external monitor. Thus, you can check if the problem is the graphics card or just the monitor internal, but in both cases, Exchange material would be needed.

Are you using the preinstalled Windows of Toshiba and what cell phone you have?

  • Why my monitor goes black after a minute?

    I have my standby power setting to turn off the monitor after 15 minutes when it is plugged.  But if I don't move the mouse or press a key for a minute, the screen goes black.  It's very embarrassing, especially if I watch a video.

    Is there another setting somewhere that says monitor going black after a minute of no activity?

    Thank you

    PAM

    Hi Pam,.

    Here's another setting worth it.

    Right-click on an empty area of the desktop and select Personalize.  Click the link to screensaver at the bottom right.  In the next window, adjust the time before the screensaver kicks in the drop "Wait" to a more acceptable value.  Click on apply, then Ok to save the change of the parameter.

    Kind regards

  • Satellite Pro A120 - wallpaper flashed black

    I have problems with my laptop. I have a toshiba satellite pro A120, but for the last two days, the bottom of my screen flashed black from time to time. Usually, it blinks for about a minute then works fine for a few minutes then flashes again etc.

    Hello

    I agree with the user above. First of all, please check this work around on cable, graphics card, etc.

    By the way: what display driver you have installed right now? Sometimes I read here in the forum that no Toshiba display drivers problems, so I recommend you to install the latest version of Toshiba directly.

    Last but not least with an external monitor, you can check where the problem is: either internal monitor or graphics card but I think that, in both cases, you need assistance from an authorized service provider to swap the part.

  • Satellite L500 - screen is completely black after stand-by

    I have a L500 and after that my computer is on standby, the tried to reactivate it. Now it will not display anything on the screen its completely black and have no idea of what should happen or do.

    Can anyone help?

    Hey,.

    You see something on a screen? The internal screen is probably defective, so you don t see anything.

    If an external monitor stays black I would try to remove the battery and unplug the AC adapter. Then wait at least one or all the night. Now connect the AC adapter and install the battery. Before you turn on the laptop, make sure that the battery is fully charged. Now, try to start your laptop and check what is happening.

    In the worst case it serious hardware malfunction and that means that you would need professional assistance service authorized in your country.

  • Satellite A200 PSAF3A - ccreen goes black after installing the graphics driver

    Hello.

    I have a Toshiba Satellite A200 which has the video adapter Mobile Intel (r) 965 Express Chipset Family (256 MB).

    I bought my computer in Australia and is the SATELLITE A200 (PSAF3A-08202D) with Windows XP.
    The computer began to be very slow, and since I had a lot of programs that I wanted more I restored it to the out of the box.

    The problem is that the screen went black after the windows logo. He worked only in safe mode. I deleted the drivers of graphics cards and it works but without a graphics card.

    Now, I can't play games or watch movies.
    Whenever I try to install the driver, no matter if its from the cd that came with the computer, the toshiba Web page or the Web site intel it still restarts black screen.

    I tried to disable the adapter instead of uninstall. When I enable it, she accepts and he will say his work but just with screen resolution of 640 x 480.

    If I try to put it above it is always black.
    Can someone help me?

    Thank you very much

    Hello

    First of all, you should visit this Australian page from Toshiba:
    http://www.ISD.Toshiba.com.au
    You will find all the drivers for this model of laptop.

    I checked and found that there is a BIOS v2.5.
    Check if the BIOS needs to be updated (if the older BIOS is installed)

    In addition, there is a display driver v14.29.1.4833 and chipset driver v8.2.0.1012
    Install it!

    Last but not least the Win XP should be updated to the latest state!

  • How to stop the monitor go black after no activity for a short time during the reading of a document?

    When I read an email or document without moving my mouse, the screen turns black after only about a minute and then proceeds to my screensaver.  I have to move the mouse constantly opening my active window.  I can't find out how to disable this "Energy Saving" so I can read the lengthy articles without being interrupted every other minute.  This was VERY irritating!

    Hello

    Open windows control panel, open personalization, click on the link to screensaver at the bottom right and in the next window, set the time in the area of 'Wait' for once you want before the screen saver appears, and click on apply. Or if you never get the logon screen, remove the check mark next to of "on resume, display the login page»  Click on apply to save the changes.

    Then open windows control panel again and click on Power Options, click Change plan settings next to your current power plan selected in the next window, set the time using the drop-down list next to "Turn wide Display" to a more acceptable level and then click on save changes.

    Note:  Set in the Options menu of food to be slightly longer than the time set in the Menu of the screen saver or you will never see your screen saver start.

  • Satellite E45-B4200 - screen flashes black

    Hello

    every now and then my laptop screen starts to blink several times.

    When he started a few weeks ago, it would be short, quick, a few blinks of black color.
    Now, the problem persists, whith the flashing more and more frequent and and blackouts are longer.

    My laptop is Satellite E45-B4200 on Win 8.1.

    Could you please help?

    The same symptoms are visible on the external screen?

    If not, the malfunctioning of the internal display would be responsible for the short and fast flashing.

    Otherwise, if the same is visible on the external monitor, the graphics card might be the troublemaker.

  • HP pavilion monitor go black after the splash screen

    When I start my pc, the splash screen appears on the monitor, but after that he's black. I can hit one of the f keys to take me to the start page or diagnosis, but when I change the path of startup and press on save, then enter it just go to the screen black I have also hit the f9 key to go to the diagnostics page and run the hp diagnostic tool edge who said past when I try to return to the screen black new go! at first I thought it was a graphics card problem so I replaced the former with a same something new, I also tried plugging three different locations on the graphics card, I started with the dvi connector with an adapter on my cable even not, it will display the start page, just go s strait to no signal , so I went on the VGA slot that has been, I can get to the start screen, finally I tried the hdmi port and again, I can get to the start screen, but then it GB Black I removed the ram and cleaned and was going to try to go to Detroit from the motherboard to the screen, but I got scared when I saw the black cap with the words DO NOT REMOVE this topic! I tried 2 different monitors just to eliminate this probability but now I am just confused ideas would be appreciated!

    Hi lostone64,

    The fact that you can see the splash screens makes me think that this isn't the video port or motherboard. My hunch is it could be a hard drive failure, operating system error, or problem of display settings. You never see a Windows screen until it goes black?

    Have you tested the hard drive or made sure it appears in the BIOS?

  • Satellite P200 - LCD is black but the external monitor is OK

    Hello

    I have a Toshiba P200 17.1 ", LCD has gone black,
    You can see the backlight in the background.
    It turns on sometimes.

    I checked with an ohmmeter lead LCD and it seems to be ok, is not sure that that is the problem.
    When I connect it to an external it follow the work ok, made his first appearance on the backlight.

    I suspect it is the LCD screen, but I would check with certainty before I part with my hard earned money.

    Question, I have a spare screen Latitude D600 14.1 ", with the same connector on the LCD (30pin)
    Could I use with inverter P200 to see if there is a signal / MoBo to the power connector.

    Thank you

    Spike

    Hello

    You must use the display 17.1.
    Your Latitude D600 screen is 14.1 "so it will not work.
