Satellite M40 - JM8 - black screen sometimes

A month ago, I got a problem with the screen, one day it's black screen and I could barely icons on the desktop, so I replaced inverter and everything was going well for 2 weeks.
After that it's the same thing (black screen). If I connect the monitor, it works.

Does anyone know what could be a problem, the motherboard or the screen...

Thank you.

You have the same problem with an external monitor?
Check it!

In addition, you should check from Toshiba Web site for a pilot to display and update the BIOS.

  • Satellite A105-S4114 - black screen, maybe the heating problem?

    Hey all

    I'm new to the Board and I really hope that someone can help me with my computer problems.
    I have a Toshiba Satellite A105-S4114. In the last week or so, it started to get a black screen. If I m in the middle of watching a video, the sound would just go to a repetitive tone (very annoying sound) and the screen freezes completely.

    He sometimes goes to a black screen. The screen is not black as if the CPU is off but it's dark and nothing is displayed. This occurs when the computer has been for a little. I have had it over 2 hours now, and if this problem persists, it will happen more frequently. I've updated all the software and windows xp. Some people tell me that my motherboard is dying and I can't do anything, but some people say maybe it's an overheating problem.

    The vent on the left hand does not always give off light, but the laptop gets hot enough. Is it possible that my fan is dying? In the case of this "black screen", the computer is not power down and for this reason, I ve people had told me that he is not an overheating problem.

    Any ideas?

    Help, please. I sprayed the CPU down to the dust, and it has gotten a little better. I hold hope that I don't need to buy a replacement right away. I've had this for about 3 years.

    Thank you, Danny.

    Hey mate,

    I think that for the moment no one can really say what the reason, but I also think it might be an overheating problem and you should start cleaning your laptop first. The point is that if the laptop is overheated (e. g. graphics card), you might get a black screen, freezes or your laptop stops immediately. So if please try to clean and follow these instructions: http://aps2.toshiba-tro.de/kb0/HTD7A01ZZ000AR01.htm

    Of course it could also be a motherboard problem but the laptop cleaning is cheaper and quicker ;)

    If it doesn t work you can access a service provider authorized professional assistance.

  • Satellite A200-1CR - black screen and no boot

    Model:
    Toshiba Satellite A200-1CR

    Question:
    By pressing the power button to power on the computer for a full boot, the power LED lights up but still black screen (not even of lighting). The logo led 'Satellite' in the lower left corner of the chassis remains off while the HARD drive has made a unique quick snap; DVD activity led (the device) always remains on even without any CD inserted, by pressing the eject button do nothing (status bar is locked) and no sounds of activity.
    No logo screen of boot (show stays), not of beeps dark and wide, no DVD or HARD disk activity, keyboard seems does not (all combinations that should light up an led, capslock, numlock, etc, does nothing), the fan works.

    I have already (without success) tried:
    -Unlock the tray, insert the rescue CD and power on
    -Remove the main battery and power on with AC adapter only
    -Insert a bootable USB stick/external HARD drive

    The computer worked as expected the day before and there has not been any kind of shock. Described is the situation I faced when I turned on the next time (only 24 hours later).

    What could be wrong?
    Thank you.

    > By pressing the power button to power on the computer for a full boot, the power led turns on but screen stays black

    Well, looks like hardware problem; Maybe the memory problem or something serious with the mother or the CPU. It of really difficult to say what could cause this.
    You can try to check the RAM modules.
    Trying to start using a maybe only module, it is useful in the case otherwise I fear, you will need assistance from technicians Toshiba ASP m

  • Satellite Pro A200 - black screen with a blinking cursor

    Hello

    I'm new to the forum and have a big problem.
    So, any help is welcome and appreciated.

    My Satellite Pro A200 turns black after the BIOS screen and a black screen with a blinking cursor.
    Also just as the screen goes black a beep can be heard which shows windows boot.

    I can access the toshiba Setup screen but not the installation of security mode.

    Kind regards

    Hello

    Please go into the BIOS settings and check if the HARD drive is listed there.
    The blinking cursor is a typical sign of a malfunction of the HARD drive.
    Eventually the HARD drive is dead and you need to replace it and reinstall the operating system.

    Good luck

    Hello

    You wrote that you can access the BIOS, but have you checked if the HARD drive is recognized properly? Perhaps because the computer cannot start HDD isn't recognized then you should check this.

    If the HARD drive is recognized, I would try a Toshiba Recovery disk recovery facility. It seems that Windows isn't able to start and if you reinstall the whole system should help get rid me of this. Go to the start menu and select the CD/DVD drive as a boot device.

  • Satellite Pro U200-> black screen after startup

    Hello

    It happens from time to time when I try to start my PLUA1E Satellite Pro U200-02802QS4, then I get a black screen even from the BIOS.
    What is wrong and how to fix this?

    BTW, I already have this BIOS version: P0044v370.exe installed.

    Hello

    This happens from time to time?
    This means that you can not reproduce this problem?

    Hmm that's not easy to say what the issue might be.
    Maybe the BIOS update will help you at the moment you can find BIOS 3, 7 victory on the European driver Toshiba page.
    If you have a lower BIOS version installed, then I recommend an update.

    It is also possible that this problem is related to some of the material; motherboard, screen, etc.
    In this case the part should be replaced but first of all it of necessary to know what part is affected and I think that the technician of the ASP for this

    What do you think???

  • Satellite C660D 15F - black screen after startup

    Satellite C660D 15F

    Hi guys,.

    I have a big problem with my laptop. When I started to-go from sleep - two days ago I heard the computer starts normally but the screen remains black. No mater how many times I tried to restart, the screen shows nothing, no message no picture. The normal operation of the side light remains on but the keyboard lights stay offshore. I can hear the computer normally (the fan etc..).

    I tried to hit SHIFT F8 start buttom on the first night, and the image was on the first attempt when I started the machine and everything seemed normal again! The next few days, I got a black screen once more and the case never worked again, no matter how many times I tried.

    Can someone help me please get out of this mess? Has anyone had a similar problem? How do solve you?

    My machine is now exactly four years.

    Thank you very much for your ideas! I really need to access some files on there!

    Hello

    Disconnect the power and remove the battery. After doing this press the power for 30 seconds about and try to reset your machine. Leave it for a while and try to start with power current only.

  • Satellite M100-150 blank screen sometimes on start/alarm clock

    My friend and I both have the same model of notebook M100-150. Windows XP is installed on two laptops. And it's very stange, but it is true that we have the same problem. Sometimes, when the os specifications, it no longer responds and white - black screen.

    If I power down/up for laptop, it loads normally. The BIOS on my laptop version is last 2.80 (updated 3 days without help). I think that there is something common in both cases.
    And one thing I can Imaging is the BIOS.

    Something wrong with it.

    Hi mate,

    almost the same discussion is here:

    If after reading this, I suggest the following before contacting an authorized partner
    (which can be found through this link: http://eu.computers.toshiba-europe.com/cgi-bin/ToshibaCSG/generic_content.jsp?service=EU&ID=ASP_SUPPORT)

    do a check of the system with "SuperPi" to check if the RAM and the processor are well and try to do a restore complete. Check for a new bios, regardless if you've ever watched.

    And then if after recovery and update all your drivers/tools/bios that did not really help, click on the link above and contact and ASP for more proceedment. (Maybe for a checkup of material and/or repair).

  • Satellite C660D (PSC1YE) black screen after BIOS update

    I tried to update my Bios on my Satellite C660D portable (psc1YE) last week (big mistake).

    Something went wrong during the update and now when I power on I just get a black screen (LEDS and fan).

    After reviewing, the conclusion is that I damaged the BIOS that must now be blind flashed.
    So I got the hand on a 512MB memory stick, formatted using FAT through windows XP and used Wincris to create a startup disk after you have added the file bios.rom (renamed Bios.wph) which I extracted the last update of the BIOS on the Toshiba site.

    My memory stick has three visible files on it, Phlash16.exe, bios.wph and minidos.
    I plug laptop with battery, DVD player and power disconnected to stick, and hold Fn + B re-connection cable cable, turn it on.

    The fan whirs at full speed, and the USB lights up and flashes then for a minute, as if being read. No matter how long I let on, the fan will continue whirring and the USB is on and when I unplug and put in still works a black screen.

    I tried different sticks, (up to 4 GB with FAT32 format), programs of different startup (for example, the HP utility) drive but still no luck.

    Can someone tell me what I do wrong? I tried to look for a newer version of Phlash16 just in case that was the problem, but can not find one any where (mine is version 2008)

    All advice would be greatly appreciated even if it's just to tell me that I'm wasting my time because the pc is not repairable.

    I can't tell you if you waste your time or not because I n know if the motherboard ROM module is OK or not

    In most cases, it should be possible to reflash the ROM module using the BIOS crisis disk but this disc is available to authorized Toshiba service technicians and as much as I know reflash this methods is not always the same

    However, in some cases it might be possible that the mobo could not be fixed by disk crisis, it would be the worst case

    I recommend you to contact a certified maintainer Toshiba to check guys would be able to use the crisis disk and could test whether its possible to reflash the module ROM
    Is it not would be not possible well in this case you would need new motherboard :(
    But lets hope do ' t you need...

  • After logging on my Satellite Pro only black screen and the cursor are visible

    I have a windows vista pro (PSAASE-00G004GR) satellite after turn on and typing the password for windows vista, the screen goes black but I see that the cursor moves & because it seems that the hard drive also works in th background, but I can't see anything except the mouse cursor , I tried to boor with other options (LAST WORK safe MODE KNOWN FEATURES... etc) but it's still the same only black screen and the cursor...

    I do not prefer the product cause of my data recovery on this subject, any ideas?
    thnx

    Hello

    You have the Satellite Pro A100 PSAAS hmm if you want to save your personal data, I recommend to remove the portable computer HARD drive and try connecting it to another computer via an external USB HDD controller. These cases of 2.5 HARD disk are not expensive and you can buy it in every store of the computer.

    Then you could try to recover the laptop delivered together with the Toshiba Recovery CD.
    But wait; have you tried to connect the laptop to the external display?
    Check it!
    Maybe you could see something on the second screen.

    I think that this procedure could be useful to clarify what s wrong.
    To me this question looks like a small little dysfunction of the FL inverter.
    In this case the installation of the new operating system will help you not to solve this problem.

    But who knows the verification is necessary to find what could be wrong.

    Good luck and bye ;)

  • Satellite L300D-13s - black screen and nothing appears

    Hi, I have Toshiba Satellite L300D-13 s (pslc8e-02p013en).

    I turned off my laptop as usual and when trying to turn it back on yesterday, I have NO screen. I can here it whirring and all my lights are on, my battery is showing green (paying), but all I have is a black screen, no markers, imprecateurs, whatever it is?
    Have I somehow turned off the screen?

    I was in battery saving mode if it has nothing to do with it at all?

    PLEASE HELP - I DON'T KNOW WHAT TO TRY

    Thank you

    Hey,.

    Normally the battery saving mode (stand-by) has nothing to it. On my Satellite L300, it works correctly and I often use this mode.

    In any case, it would be interesting to know if you can see an image on an external monitor. The internal monitor FL inverter is may be defective and so it does not show an image... Who knows? ?:|

  • Satellite L350D - 11K: black screen after downloading the Tempro updates

    Hi Forum,

    yesterday, I admitted Tempro download several updates on my satellite L350D - 11K.
    During the last update, it was an update of the firmware, the system crashed, and it no longer starts.

    After removing the battery, the system starts up, but now it has a black screen and I don't know what to do.
    Pressing any key F doesn't show any results and I have no recovery CD.

    Does anyone have an idea what to do?

    Thxxx in advance

    Hello

    I don't know why it happened, but if the short workaround solution posted by boarder will not help, so I see good opportunities to contact the ASP in your country for assistance.

    > During the last update, it was an update of the firmware, the system crashed, and it no longer starts.
    You're talking about the firmware update
    Maybe it was a BIOS update which failed and so the laptop will not start again
    As already said in this case that only the ASP technician could help you.
