Problem with matrix/screen in Qosmio F55-Q502

Hello

For a few weeks, I have a strange problem with matrix/screen of my laptop.
The matrix flickers very often - no matter if the power cable is plugged in or not.
The screen is full intensity and all of a sudden it starts flashing - it gets darker, lighter, usually for a few / dozen seconds. It does when no one touches or when I'm working on it.
This very annoying and making eyes tired - he does it very fast and there is few levels of screen brightness.

In addition, sometimes the screen turns off - you can see what is on the desktop but the screen is very very dark (but not empty or completely off). No reason - sometimes just in the workplace, sometimes for example when I touch (not pull) the power cable between the laptop and the power supply.
Then, the only way to return to normal brightness of screen id to close the lid just for half a second and open it
-matrix comes on normally, but can 'turns off' moment later and I have to do it once more - sometimes even several times...
After 'action' with cover screens it seems that nothing ever happens...

Anyone an idea what is the cause of such behavior or how to diagnose in details?
Or maybe solve this problem?

Best regards

Sounds like the backlight or inverter fails, or there is a bad connection.

Is the unit under warranty? Send it to an ASP for repair.

You should avoid to repair yourself, the backlight is very high voltage!

  • Qosmio F55-Q502 - charging icon says: plugged in, not charging

    I recently had my Qosmio F55-Q502 repaired by Toshiba.
    Two issues have been addressed, and one is fixed.

    However, the second attempted to decide without success.

    When I try to play multimedia games such as call of duty IV, even if the system is completely loaded, a few minutes the system will begin flashing the "Backlight" and then when I see the loading icon, he says: "plugged in, not charging.»

    This really worries me because I read online many similar questions, but none of the solutions seem to work.
    Having to reboot every time that happens and your in the middle of a game, really STINKS!
    I even had what is happening with SimCity4 which is an old game.

    Any suggestions on this good?
    Did they replace the battery when it was sent to which seems to be what most needs to be done.

    Hello

    If your Qosmio laptop was being repaired, I think that you should not discuss any issue on the forums, but put a pressure on the service and specify every single problem with your laptop.
    Please do because the warranty is still valid and it is now time to clarify everything.

    I am not an expert in hardware, but it sounds to me like some electronic power supply question but I can't say for sure. Speak with the service. Try to clarify this with them. Be nice, be cool and all will be ok.

    > Is it possible to buy the internal bluetooth module for it (for example, Q503 model) and if so what is the model number of this module and where I can buy it?
    The laptop was equipped with Wlan 802.11 b/g/n and integrated GPS. Seems the BT is not available and you cannot insert an internal BT module. I think that external amn BT USB stick would be ok too.

    I don t think so.

    > Is there any modem HSPA (on PCI Express Mini) compatible with this laptop?
    I put t found all ports on this laptop modem so it seems that there is a modem installed and there is no possibility for any update.

  • AMD Radeon 7570-devices is not compatible with Windows 10 - you're going to have problems with your screen

    Microsoft will come out with Windows 10, as an upgrade of the free operating system next month, July 29, 2015. They came out with an app, 'Get Windows 10', which is intended to help the operating system upgrade process. In this app, it checks for compatibility issues that may exist between your computer and their new Windows 10.  I get results for two of compatibility issues when I run this app. The one that concerns me, it is with the video card that came with my computer, AMD Radeon HD 7570.

    The app tells me: "these devices are not completely compatible with Windows 10" and he adds "you will encounter problems with your screen."

    Is there any driver updates that resolve this problem?

    The driver, I installed on my pc is Advanced Micro Devices, Inc. version 8.960.11.2000

    Windows says that the driver is up-to-date.

    If no driver is available to correct this problem will be I need to replace the video card in my computer and if so with what?

    I currently use two screens, a LG 22EA53 (analog) and an Acer S230HL without any problems with Windows 7, Home Premium, Service Pack 1.

    Malygris1,

    Well, son of a gun... looks that microsoft has made changes in their updates.

    Now when you run the "'get 10 app Windows, check your PC ' it reads in devices..." "0 problems found."

    Looks like Microsoft do with last-minute changes, as you indicated, and others have mentioned about being patient on this matter, that they may (?) have addressed this problem.  Probably won't suddenly course up until the update is done.

    Guess for now, I have to score this as accept as a Solution.

  • Satellite Pro L20-someone ' one can tell me if I have a problem with the screen?

    Hello

    I have a Pro L20 - PSL25E and I recently had problems with the screen, it was intermittently flickering/lose color and whiting almost (when the color fades white vertical lines begin to appear).
    This seemed to worsen after that I dropped it (only from about 2 feet off the ground, not a big drop).

    I thought that the sceen can go, but the performance of the laptop seems to be affected when this happens, the laptop started to run very slow (tracks mouse slowly, programs I clicked take ages to run and it freezes sometimes to stop flashing) that had me thinking that it might be a virus or performance problem.

    My screen, drivers are updated, I did a full scan with McAfee, ran a clear-up system and a Defrag.

    I was wondering if anyone knew if it seemed to be a problem with the connections of the screen and would need replacement or if it could be repaired or if it were a performance problem?

    Any help would be great thank you appreciate!
    Rebecca.

    Looks like the graphics chip has a problem, which I think is a motherboard replacement.

    You can get a quote for repair to an authorized service provider. There is a list of ASP on the Toshiba site.

    Since I have the card nvidia geforce 9700 m gts first, I downloaded the nVidia drivers on the download of Toshiba page extracted all for the office and ran the setup.exe but I got this error:

    After that happened, I decided to try the 64-bit intel display drivers to see if it worked but I got this error:

  • Problem with switching screens

    Hello, I have a problem with switching screens. Here is my code (both screens extends screen):

    SerializableAttribute public class Main extends UiApplication {}

    Private TrainLinkScreen trainLinkScreen;
    Private WorkingScreen workingScreen;
    private string;

    Public Shared Sub main (String [] args) {}
    new hand (.enterEventDispatcher ());
    }

    public Main() {}
    workingScreen = new WorkingScreen();
    pushScreen (workingScreen);

    try {}
    trainLinkScreen = new TrainLinkScreen();
    } catch (GpsException ex) {}
    message = ex.getMessage ();
    } catch (FileException ex) {}
    message = ex.getMessage ();
    }
    If (message! = null &! message.equals("")) {}
    invokeLater (new Runnable() {}

    public void run() {}
    Dialog.Alert (message);
    System.Exit (1);
    }
    });
    } else {}
    popScreen (workingScreen);
    pushScreen (trainLinkScreen);
    }
    }
    }

    The problem is that the workingScreen is not displayed. The download takes a little time, so I wanted to put here a screen like "I work, please wait...". ", but he appears, the unit freezes for a few seconds and then the trainLinkScreen appears. Could someone please write where is the problem? I tried invokeLater on the first screen, but it ends with the crash on popScreen (trainLinkScreen). I tried invokeLater on trycatch also block, but it does not work either. Help, please.

    Thank you. I already have the solution (I hope that ), I put to device gps location in a separate method (it's a small part of the code that does not have too much time to finish), she called before initialization and initialization in method invokeLater as a thread (the large part, too download from the internet). The display works perfectly in this way (in the first place, the "Download" screen appears and then comes the rest of the code) Although some other things seems to not work properly now

  • IPhone update (but an old having problems with the screen Activate iPhone and Apple ID)

    I have an iPhone 5 that, by chance (Pocket escaped), is stuck on the screen of the iPhone 'Find your phone' Activate.  The iPhone does not accept my Apple ID.  He is looking for an address icloud.com.  I can't honestly remember a set up, and I tried a number of variations on the icloud.com address (using the 'index' system provides) and passwords with no luck.  Do not have any problems with my Apple ID - I can see my phone & details on my screen of the user, when I connect my account (via the office).  Subject to my cellular service provider, I tried to force a restore on the phone via iTunes, but after that he asked me a few questions of initial Setup, I'm just at the "Activate iPhone" screen

    To be honest, I was going to pick up a new phone this week anyway.  My concern is now that I don't want to not suddenly faced with the same problem.  This lock, I meet - is - this quite specific for the phone itself? If I get a 6 plus and use this Apple ID to activate it, I ask in trouble? I admit that I am a twit when it comes to activation codes, the Apple ID, SIM cards and others.

    It was my first smartphone (+ 3 years now) and the installer was made by my employer, so strange things could happen at the beginning.

    Thank you all for any help

    If the implementation was made by your employer, they can put in something different from your Apple ID to find my iPhone. It also seems that if something was damaged in the fall. Who can contribute to the problem.

    If, when you receive your new phone, you make sure you use your Apple ID to find my iPhone, you should have no problem.

  • Qosmio G20: Problems with tuner TV and Qosmio player on Linux

    Hello!

    I would like to install a Debian's Linux distribution based on my machine... But it looks like there could be some problems with a TV tuner and the qosmio player.
    Is there someone who could help me with a viable solution for this?

    Lasse

    Hello

    Well, you need a TV tuner driver, but the problem is the LINUX operating system.
    There is no drivers for Linux. Toshiba doesn't supports Linux. In addition, you will not find also all the drivers.
    All you can do is to use the Windows operating system. The Knoppix and Kanonix are very nice Linux distributions. You can run these Linux from the live CD. You n t need to install anything.

  • ThinkPad X 230 Windows 7-64: problems with the screen after updates

    Hi all

    I have a problem with the Thinkpad X 230. After a recent update of Windows 7 (64-bit), the screen resolution is set to 800 x 600 and brightness to the minimum. FN + F8/F9 does not work. The brightness is uncontrolled. I had to restore the system before the update.

    How to solve the problem, do anyone know?

    Thank you!

    Isosik

    Hi Isosik,

    Welcome to Lenovo Community!

    According to the request, we understand that you are facing problem with the display resolution on your ThinkPad X 230.

    If you have updated the drivers from Windows update, sometimes this kind of problem occurs with windows generic drivers for cause of driver incompatibility, suggest always update drivers only via the ThinkVantage System Update utility. Update only the application of Microsoft Windows Update.

    You can also manually download the drivers from the Lenovo support site.

    Lenovo support site.

    I hope this helps.

  • I'm having a problem with the screen resolution cannot be superior to 800 x 600 pixels

    All this began after I plug an i9 phone to my pc to load

    later, to this day, when I turned on my pc screen resolution would not stay how I put it

    He wants to just go to 800 x 600 pixels.

    I ran microsoft security scan it found and deleted a virus java exploit cve 2010-4452

    but still having trouble with the screen resolution

    If the problem occurred after you plugged into your phone. I suggest to perform a restore of the system automatically, put it on a date 2 days before you had the problem. If this isn't the case, you can check the video card driver:

    Start > run > devmgmt.msc
    Check your video card driver or see if there are any missing drivers
    If its lack, then update or install the driver of your video card.
    I hope this helps you! Good luck.
  • BlackBerry Smartphones having HUGE problem with the screen

    Please help me people... My flipberry went completely crazy...
    I ' l try to explain the problem with as much detail as I can remember...
    Since last week or both internal as external screen my phone acted crazy...
    for the start of a few days, the problem started with the internal display will red sometimes, or show the half of the screen with stripes of colors... I thought it was a passing phase...
    but after a few days, the screen went completely black... both screens external and internal... until this time, as I ran the firmware 4.6.0.222
    so that day I sat down and wiped my phone completely and loaded the latest firmware 4.6.0.236... in order to completely black screens are returned to the way they were... sometimes ok, sometimes showing abstract things and weird colors...

    and even today both screens went completely black... so I'm currently trying to get back to the 4.6.0.180 version as recommended by t-mobile...

    and I have not dropped my phone once again since I bought it 4 months ago... need help

    usually the phone will come with a free warranty of one year.  The best thing I can suggest is to return to the top of any data you left phone and bring it back for a replacement or sent it to be repaired because it seems to me that your phone is defective.

  • Problems with the screen resolution, Cloud based software and Photoshop after the last round of updates Windows 8.1.

    Original title: screen resolution problems.

    Since the last series of Windows 8.1 update the resolution of my monitors has been changed for the worse. I use an AOC 2367 M (resolution 1920 x 1080) as my first monitor and a 42 inch Sony Bravia (resolution 1920 x 1080) as my 2nd monitor. The changes are more noticeable on the Sony Bravia and any adjustment I make to the resolution only make worse it.

    I also have problems with some software clouds as I load using citrix and when I try and navigate once opened software, I can't because the pointer selects a point about 50 mm on the side of the where he is hovering. In fact it is very difficult to open and close as anything and I resorted to the laptop to get concrete results.

    Photoshop now also comes up with a message when I open it up to inform me that the monitor profile seems to be defective.

    Any suggestions would be helpful as I thought initially an another upgrade must follow to correct the ills of windows 8, but appears not to have happened.
