Screen is dead!

Hello!

Changed Reecntly lcd on my xperia m4 aqua!

Worked well for 2 minutes. When I was unlocking patters screen went black, imagined perhaps locked itself. tried to unlock it! I could feel the vibrations and sounds as I type my code, but the screen is black. Thought that perhaps the display is dead. Opened again. Put on the former and the same problem. Phone works but the screen. Tried to reinstall android. Did not work.

What could be the problem and what could be the cause?

    At startup. I go as far as the login screen (showing the four accounts). But this screen is dead: there is no response to finger taps or gestures. only by pressing the power button gets a response (immediate panic stop)

    There is a story backward. Yesterday, at the start, I received a popup saying "message wants to use the login keychain, enter the password".

    You have no pre-test question slide or you branch to the current activated in the Quiz settings?  Which will disable the playback bar.

  • Satellite R830 screen problem - dead pixel

    Hello

    I have a Satellite R830, I haven't used the laptop a lot since the purchase 2 years ago but I have several white spots on the monitor (8 + areas). I suspect that these may be hot spots of pixel, but I've tried all kinds of software and even slight pressure repair but nothing seems to work.

    Someone at - it Advisor on methods to try to resolve this problem or am I resolved to try to get this repaired?

    Thank you

    Hello

    You can not fix it
    In this case the display must be replaced.
    But I guess that the guarantee is no longer valid, so you pay for the replacement.
    I think that it is not worth.

    I also found information on the technology screen and tolerance fault pixel of the LCD poster

  • Satellite L850-1JH - dead, screen too dark

    Hi all.

    I had a problem with this laptop for the last four weeks.

    One day worked, it normally stops and the next day when I power the screen was dead.

    The fan stands up and lights, caps and numlock function, but not picture.

    There are also 3 days ago, I noticed that if the screen is tilted I can actually see the Toshiba logo at boot and then a few icons on windows 8.

    For what I found online that this laptop doesn't have a UPS because she is LED which requires current DC which is quite a new thing on laptops, I think.

    One thing which I use to to check if there was any kind of output image has been to connect the laptop to the tv, but for some reason, that no picture is via vga or hdmi port.

    That being said I'm reluctant about the fault being the monitor. One thing I'm positive, I can certainly see very dark and with the monitor image tilted slightly.

    Someone had a same or similar problem?

    See you soon.

    Albert

    I ve never been faced with this problem on my Toshi and cannot say for sure what the problem is here, but my opinion is that you should contact the nearest Toshiba service provider and ask for help.
    I assume that the warranty is still valid for repair, if necessary, will be free of charge.

  • Satellite A300-16W - now blue screen on system

    I have Satellite A300-16W 21 months and so far my cooler was also changed HDD, screen was dead (had to be changed to), was to motherboard, then I had the problem with the battery charging and which had to be fixed too. Now, the whole system cracked, blue etc screen. So far, this computer was nearly 160 days for services and I'm really disappointed with toshiba, because this is the worst computer I've ever had. I lost very important data twice because this computer.

    What to do now? I think it would be fair for toshiba to give me a computer of the same price I paid for this one because it is obvious that it has and it will be a lot of major problems and failures.

    Hello

    I can understand you, Milosh. It seems that you don t luck with your Satellite A300 but I think that if an individual case. I've ever read in the forum about these problems on the Satellite A300 and friend of me has also the same laptop but without any problem.

    You know that nobody is perfect and laptop use a lot of electrical parts and no one can say how long they life.

    If you are not satisfied, you can buy a laptop. That is your choice but don t forget these things can happen with other laptops too. Of course that's not normal, but theoretically it can happen with other mobile / manufactured too.

    About your important data, I can only say, make a backup from time to time!
    Which is the most important thing you need to do. Use a good backup software Acronis True Image. Installation and configuration of such tools to take just a few minutes, but if you use them, you are on the safe side! :)

  • Re: Satellite L735-158 - black screen in BIOS update

    Hi all

    I have not found a solution to my problem anywhere, so I'll try here.
    I was going to update the Bios on a Satellite L735-158.
    I went to the Toshiba´s website, downloaded and follow the instructions... but the app. 15 seconds after double-clicking on the file of orders... some sort of sign of error came.

    The computer "locked" and then the screen is dead.
    When I turn on and off with the switch, I can clearly hear the computer works (although strangely), but the screen is dead.

    Can anyone here help?

    Thank you
    G

    Of course the EPROM module where the BIOS is stored was not flashed properly.
    Something went wrong during the update of the BIOS and the module is bad.
    I suppose that the update procedure using the special crisis disk BIOS help you solve the problem.

    But in most cases this procedure must be done by Toshiba ASP.

    Alternatively, you can search the forum for a few similar discussions on the crisis disk BIOS here.
    Some users where it is able to solve this problem by using some 3rd party disk but it doesn't always work.

    So is probably that you last chance to repair the ASP from Toshiba

  • Satellite L350, mette, black screen, no BIOS, no splash screen

    Hello

    I am a professional (DHL Aviation)
    I support a user that I advised to buy the Toshiba because of my great experience with it.
    Laptop is about 3 years - W7 Ultimate.

    Problem: computer laptop is not starting at all, screen remains dead, only powerlight and fan says he works. No BIOS screen options, no Toshiba welcome screen, nothing...

    Laptop MOBO power. Power light is on when on the current power of light work light Central (illegible icon) is orange, no other active lighting.

    Low start and keeps running fan.

    Measures taken so far:
    (1) remove all power and press the power button / stop for 30 seconds then restart
    (2) memory reinstall
    (3) replaced HARD disk
    (4) blew fans (the user is a smoker - now STINKS like HELL)
    (5) tried to start a liveDVD Fedora & Fuduntu, begins to turn, but then stops turning. No OS seems to be loaded into memory.

    No change

    Any help would be appreciated - thanks in advance.

    > Problem: computer laptop is not starting at all, screen remains dead, only powerlight and fan says he works.

    No BIOS screen options, no Toshiba welcome screen, nothing...
    Sounds like motherboard problem if the Toshiba start screen does not appear, it means thet POST (power self test) may not the product, which means that it is a junk motherboard

    I think you need to replace the mobo ;(

  • Installation of the HP 550 display driver > black screen; restart: black screen.

    It seems my HP 550 (Celeron 1.73 GHz, 2 GB ram, x 3100, graphics etc.) does not accept the display driver which is available at the hp driver download page.

    I also tried an of intel directly, with exactly the same results on W2k SP4 and Windows XP SP2 home edition.

    During the installation of the driver, at some point after the copy, the system goes to a command prompt-looking on the back with a cursor blinking for a few seconds, it looks like its running a batch in full screen or similar file.

    After that, I guess, try to use a new display mode - without guest - and breaks down (screen becomes quite dead).

    I have to turn the system and then turn if I want to do something with it.

    Windows seems to start, but after the logo "xp" screen gets dead/black again.

    On a normal pc I start in safe mode and change the display settings, but I can't do with this laptop for some reason any:

    After starting in safe mode, I can't change the resolution or color settings, and also I can not change the settings for the "monitor".

    (The monitor settings are just disabled, the color and resolution can be changed, but apply new settings just does not do anything).

    IM at a loss, and, since I have no experience with laptops, I came here

    Here is the link for the driver, I just at the exit of the site to intel:

    http://Downloadcenter.Intel.com/Detail_Desc.aspx?AGR=Y & ProductID = 2800 & DwnldID = 17353 & strOSs = 44 & OSFullName = Windows * % 20XP % 20Professional & lang = fra

    hp driver I've tried is 'sp39798 '.

    Thanks in advance for any ideas...

    I wanted to just report, I just formatted the entire hard drive and reinstalled from scratch with a different win xp cd (sp3 and sata drivers included), now the gfx drivers work as they should and display works fine.

    Good bye

    Hi Robert,.

    You will need to contact your Service partner allowed the closest to get a breakdown of the cost to repair your laptop.

    It is very likely that you can claim the cost of repair against your house insurance content (I did when my A30 fell on the ground and broke the optical drive).

  • Satellite P300 - HD 3650 watch the screen when active

    Hello. Thanks to anyone with additional ideas on how to solve this problem.

    When the HD3650 graphics card is enabled on my new (bought yesterday) satellite screen is dead. As in, no power at all. Even when I plug in an external monitor. It works in safe mode with VGA however.

    I took the following measures:

    1. reboot with no battery as it is said in the FAQ.
    2. set power-> CPU options minimum power in the form of 5% to 100%
    3 disable the adapter 3650 in safe mode so that I can start the computer normally. Applied BIOS update 3.4, Chipset and GFX all drivers updated. No effect.

    So apart from the usual lack of updates of software and the driver I can't seem to get the GFX card to work.

    Are there other config adjustments or updates that I should try?

    Thanks again.

    Hello!

    For me, this looks like a hardware malfunction.

    In your case I bring the laptop to the computer dealer and request a new. Or contact you nearest authorized service provider. Technicians can check your laptop and fix it.

    I assume you are using the settings of factory and you don t have your own version of Windows or a display driver that is not Toshiba?

    Good bye

  • Satellite 2410-303-help with replacing the LCD screen

    Hello
    My screen is dead and must be replaced. Can someone tell me where I can get a replacement and at what price? I live in Mauritius and cannot get spare here.
    Thank you mnay
    Jawa

    Hi Jawa

    In my opinion there is not a lot of options. You can order parts by authorized service partners or order it from some independent PC shop. Check if you can find a partner in your countries, or maybe someone else (they can send you everything you need to). Another way Google a little bit and I'm sure you'll find someone who can send you a new LCD screen for your laptop.

    On the price I can't tell you much because we walked free and the price is different from one country to the other.

  • Satellite P100 will not feed or has white screen

    So, I have this laptop I missed about 4 months ago. Not feed the most. I can press the Start button and it looks like his work, but there is nothing on the screen. I can hear the fan from time to time, then a beep after about 1 min after 'start-up', but screen seems dead. Nothing appears on the screen at all.

    I tried with and without battery power.

    My laptop can become very hot and freeze that I remember.

    I replaced my Toshiba with another laptop but if my Satellite is not going to work again is a way I can get the files out there still?

    Thanks for your help.

    Hello

    > I replaced my Toshiba with another laptop but if my Satellite is not going to work again is a way I can get the files out there still?
    You need the data and files from the internal HARD drive?

    You can access the connection data the P100 HDD external USB HDD to the other computer.
    You could remove the HARD the P100 drive and could insert into an external USB enclosure
    I think that the HARD disk supports the SATA interface, so you have to get a SATA USB caddies

    With regard to the question P100;
    Well, it seems to be a hardware problem, we can only speculate about the type of dysfunction, but for me, it looks like a serious problem
    The best is to contact a technician for laptop and check the single parts

    Good luck

  • Help! W500 dead. Is update system, restarted itself, makes 3 loud beeps and thats all!

    I just changed my hard drive, stuck in a windows 7 cd, successfully installed. Chrome, dropbox and update system installed. Ran Lenovo update system and at one point the computer restarted itself, made three loud beeps (long followed by two short) and that's it.

    The bluetooth led is on, as it is powered, battery and charger lamps. The screen is dead.

    That's happened? What are these three beeps? What should I do?

    It turns out that my new HDD is loose. Something must be done to ensure that it does not move.

    It was a scary time.
