Satellite L450D-13U - screen will not come

I have a laptop Toshiba Satellite L450D-13U with 2 GB of RAM and no hard drive.
My problem is that the display does not illuminate. I tried all the well known stuff and stuff like taking the battery, power down etc button but nothing seems to work.

Can't even connect to an external monitor. Is there a part that I could change what can help this problem?

Thank you very much

Without any serious diagnosis, it is not easy to say what the problem is. Perhaps is faulty display.
By the way: what happening exactly when you press button walk / stop?

  • Satellite P300-156 - screen will not come

    Hello

    When I turn on the laptop, all the LEDs come on as usual, including the band of touchpad and media buttons, but the screen is totally blank. I hear the disk hard being accessible and see its LED twinkle according to a normal start, but the screen is totally empty through the full boot and lights never.

    It doesn't seem to be consistent with the problem. It's twice its arrived now in 2 days, and it took me about half an hour on two occasions to finally get the screen to come to life by making many power on / power offs (holding down the power button), removal/reinsert the battery.

    Has anyone encountered this problem before? Any ideas on a solution?
    I guess it's a ribbon cable problem maybe.

    Thank you very much

  • Satellite L555-10N screen will not shut down after 10 minutes of non-use

    Hello

    I recently acquired a laptop Satellite L555-10N, which so far has proved to be a good choice.
    I have a little problem, however:

    In the preferences of my energy, I put the time during which the screen should turn off, 10 minutes, if the laptop is not in use.
    Although this worked well for the last few days and weeks, the display now will be not closed at all.
    I did not change the BIOS or driver or whatever.

    I remember to change some preferences in the configuration ecoUtility to enable.
    At that time, I received a message that preferences should be modified to enable the functionality and I agreed.

    I could not notice any changes have been made, but from there, the screen off more.
    I would appreciate your help!

    Thank you!

    Hello

    What operating system you are using?
    For Vista and Windows 7, I founded a good article on Windows power management settings:
    http://APS2.toshiba-tro.de/KB0/HTD84026Q0000R01.htm

    In addition, you can change the settings for each profile. This means that you should choose turn it off the display function for this power profile that you use or all profiles, if I used all of them.

  • I updated adobe and now windows vista will not come to the top!

    I was doing something that requires adobe 9 or higher, so I updated to 10. Now my main screen will not come to the top. I can't do all the suggestions for troubleshooting because I can't get to my computer at all.  I validated and it says windows Pascal more send activationsetc. and I can't update because I can't.

    Try to start in safe mode (press F8 immediately and repeatedly after Power Up Self Test and before Windows starts) and uninstall Adobe Reader X.  Then try to restart normally.

  • My Dell is power saving mode and will not come out

    My Dell is power saving mode and will not come out? Any suggestions? I can't get anything else than a screen that says it is in power save mode and press a key or move the mouse. No one who does nothing. Don't disconnect.

    Hi Ma32206,

    Monitors Dell will automatically mode energy saving after a predetermined time amount when the computer is idle. The Dell monitor will go completely black, rather than display a screen saver. This allows your monitor to essentially turn off until it takes again.

    A. Press any key on the keyboard or move the mouse. Either will automatically turn off the power saving mode. Alternatively, you can press the power button on your Dell computer tower or laptop.

    B. press one button a second time if the monitor goes power saving in standby mode. Standby mode allows the screen saver appears.

  • Windows 7 splash screen will not change after the vista update

    After updating vista 32 bit to windows 7 32 bits, the splash screen will not change and he showed the vista boot. I read a lot of forum and the web page, but this solution:

    «.. . the dummies and bad start screen for Windows 7 is due to the locale entry in the startup folder, which could not be set when editing or rebuilding the BCD. When the locale is not found, Windows boot loader doesn't know what local startup folder to look for the animated bootscreen. Thus, in order to fix the boot screen so that the splash screen can be re-established, restored or reset to original animated Windows 7 boot screen, just run one of the following commands at the prompt with administrator rights:

    bcdedit/set {current} settings regional en-US

    or

    BCDboot % WinDir % / l en

    Change the US to the language version of Windows 7 installed, as ja - JP, en - us, es - ARE, pt - BR, zh - CN, zh - TW, fr - FR, fi - FI and etc.

    Restart the computer after running the command to see the new boot UI (user interface) be used again. To check if the locale has been entered properly, just run the bceedit command in the command prompt that is running as an administrator... »

    not solved my problem and also know for many users... after updating vista in windows 7 splash screen stay the same...

    OK, here it is incase anyone ever have this problem. I changed all the instance names as theCall and theName to variables. For this change in the area titled var: sort of in the lower right corner of the properties. I also changed the shape of the POST method and made my form a clip called sendWork

    Well here are the scripts.
    I'm still having a problem with my if statements. They stopped working after I changed everything to variables. He would still put me to the error screen that I put in place even when I had all of the information entered.

    I know it's because they are implemented by using the instance names (see above the script), but when I say that everything will work smooth, if all goes well

    Stop();

    Each time Firefox opened

    Hello Darryl.

    It is possible that you have a problem with some Add on Firefox which is an obstacle to the normal behavior of your Firefox. Have you tried to disable all add-ons (just to see) to see if Firefox goes back to normal?

    Whenever you have a problem with Firefox, whatever it is, you must make sure that it is not caused by one (or more) of your installed modules, whether an extension, a theme or a plugin. To do this easily and cleanly, start Firefox in safe mode (remember to select disable all add-ons when you start safe mode). If the problem goes away, you know that it's an add-on. Disable them all in normal mode and allow them one by one until you find the source of the problem. See this article for more information on troubleshooting extensions and theme and this one for plugins.

    If you need help with one of your modules, you will need to contact the author.

  • Satellite A100-225 screen does not load

    I have a toshiba A100-225 and whenever I start the laptop the screen will not load or show anything. Does anyone know what the problem with him?

    Hi Michael,

    The screen itself may be defective or the FL inverter has failed. Try to connect an external monitor to your laptop and see if you can get a good view. If the external monitor does not work then it is probably a problem with your graphics chip.

    Kind regards
