Lines on screen Qosmio G20

Hello

I hope that someone help me with this, there are (different colors) lines from the top to the bottom of my screen. It started with one and the number of these lines started appearing day after day, I have about 25 of these lines at my last count.

Test it with external monitor. If the lines are there again, it may be because of the faulty graphics card. If this is not the case, then is probably the screen the reason why this happens.

    Hello, Fabian

    I'm very sorry to hear that you have a problem with your Qosmio. I have too many Qosmio G20 and I really like this camera. I know it is expensive (I bought an opportunity), but it's really a very powerful and noble device.

    Right now my works well but when I read something like your ad that I'm a little worried mine too. I have gift? t know how long warranty period is in your country, but especially about 2 years ago. Try to contact the Service partner in your country and speak with them. Maybe is it possible to fix it.

    Good luck!

  • Vertical lines on screen - Qosmio F10

    I need assistance with vertical lines on my screen.
    It began before the period of one month, and I don't know what to do.
    Now, I work in SafeMode because Windows XP used to operate normally.

    The service where I bought it, they say I have to buy the new motherboard because the graphics card is integrated on the motherboard and graphics card loses contact with the motherboard.

    Now I should spend about 900 to buy the new card mother and graphics card, but it is stupid because I bought new Toshiba before 2 years for 2,000 and now does not work normally.
    Does anyone has a good idea how to fix it or some pages where I can find parts for my Qosmio? It is easier to say that someone to spend 900 to fix.
    Where are now best Toshiba notebook that everyone talks about.

    Help, please.

    Kind regards

    Hello

    I can really understand you and of course it s very stupid situation, but I guess that the guys of ASP are right and this problem really looks like a graphics card problem.
    The vertical lines on the screen are very typical for a malfunction of the graphics card.

    So I see really no other possibility as to replace the motherboard.
    Maybe you can buy one second hand and it could be a little cheaper.

    PS: I bought an extended warranty with my new laptop and I recommend to all this extension because a hardware malfunction can always happen.

  • Green lines on screen - Qosmio G15

    Someone has put in place if there is a serious problem with the motherboards in the Qosmios? I have now experienced the second failure of motherboard in my G15. The first was in December 05 which was replaced by Toshiba. Now it happened again 6 months later.

    I love the computer, but I am very concerned by the machine

    Hello Richard

    I found a few topics on this forum with similar theme. One of them that you can see on http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=9337&messageID=34323

    Try to connect the external monitor and see if it happens again. If so there must be a problem with the graphics chip and the main Board. I don't know but I read somewhere that this is known issue and service partners have a new Board of Directors main graphics chip with more recent. This means that you will get much better graphics card but it produces more heat and the cooling fan runs very often and for longer. The second problem is that power consumption is a little higher and the battery life is not as long as before.

    Sorry, but you need to talk again with service partners; Ask them about this info with the main Board and the new graphics chip. There are also guaranteed for new pieces of equipment.

    Talk with them. Good luck!

  • Qosmio G20 screen of text or symbols on startup

    Qosmio G20 139, at the start of the Qosmio laptop appears and then it immediately goes into a screen of text or symbols. Is continuous to load see the Windows XP screen then displays vertical blue dotted, then goes to an error page showing the nonpaged page error error 0 x 00000050. Then restarts and goes around and does the same thing.

    I used the recovery disk and it worked fine for a few days the have reappeared.
    I checked the ram and hard drive and there seems to be some errors.

    Now reinstall drive does not load correctly.
    If a page comes up saying installation is not complete.

    > I checked the ram and hard drive and there seems to be some errors.

    How did you check that?
    Have you used a new test strips of memory and the new HARD drive?

    To be honest, I don t think that your HARD drive is affected. The vertical dotted lines, could be more related question of graphics card in terms of the HARD drive.
    RAM question could also be possible, but I think that its GPU.

    By the way: you are able to access the BIOS?
    Turn on the computer and press F2. Then leave the laptop in BIOS for a few hours to check if some problems arise.
    Would be interesting to know how the unit would be

  • Vertical pink line on Qosmio G20 LCD

    Hello all,.

    The screen of my Qosmio G20 was displaying a pink vertical line (exactly 1 pixel width) whenever it returns a long out-of-State (i.e. at startup, wake up from hibernation, etc...). The line persists for only a few seconds to gradually disappear the transition by means of green (and maybe white) before to do so. It is also worth noting that the pink line does not appear on his return from a short off the coast of the State.

    Unfortunately I do not have external screens on hand to test if it's a hardware or software problem, so I was wondering if anyone out there has experienced this before or pink line if there is a clear diagnosis for her (I suspect material myself but...).

    Kinder,.
    Lee.

    Hello

    Seems your equipment malfunctions but it s, not easy to say what's wrong without a detailed test.
    Everything is there, we can provide suggestions only.
    Of course, it s might be the graphics chip to malfunction, but I wouldn't say that this s REALLY a graphics card failure.

    The connection to an external monitor would be useful to provide some additional suggestions...

    However, you will definitely need assistance service guys because I don t what you'll be able to fix it yourself.

  • Qosmio g20 - best replacement screen?

    Hello

    My lcd screen has lines running down it (different colors) and is wide right vertically blurred 2inches in the middle.

    Now I'd like replace the LCD 17 inches but theres more than 1 part number to pass.
    I have reference numbers

    LG Philips LP171WP3
    N170C1-L02

    both are WXGA + 1440 X 900 display, SUPER HIGHBRIGHT (BRILLIANT) XBRIGHT.

    So which one to buy?

    Thank you

    Well, the replacement of the screen is a costly affair!
    The LCD is one of the more expensive parts of portable (apart from the motherboard) then maybe you should make a choice between a party of second hand and the new screen. If you wanted to buy a new screen and then you would have a new warranty but it s more expensive. On the other hand; no little cheaper warranty

    A new LCD can be ordered from the ASP in your country. I also found this site useful:

    Thank you guys

    Of
    Sweet

    Hello

    I think display of the G20 should be compatible with the Qosmio G10 display.
    I searched a bit and found that the Qosmio G10-100 PQG10E was fitted with the 17 "WIDE XGA LCD.
    The Qosmio G20-101 PQG20E supports the same 17 "WIDE XGA display.

    Therefore, it seems that both units use the same screen.

  • Qosmio G20: How to get rid of the large green volume screen?

    Hello

    I have a Qosmio G20 I bought at the Japan last year and have since changed drivers and English operating system. However one thing ive noticed, distinguished by the Japanese put in place, it is that whenever I adjust the Volume level by using the wheel on the right side of the laptop, a large green level Volume display appears on the screen. I want to get rid of this cos it takes place close to half of the screen. The Japanese version had this problem.

    I checked all the settings in the Panel and the various sections of both properties but couldn't find anything.

    Suggestions how to remove it? Qosmio users have this on their screen?

    Thank you.

  • Gray glittering color screen on Qosmio G20-120

    Hello
    I have a problem very confusing with my new Qosmio G20 - 120.
    I can see vague and wink on my screen when the brightness is set to 2 or 3 levels under the maximum, and the background of the display is set to dark grey (or other color non-black)
    This effect disappears when the brightness of the display is set up, but you know, I can't work with the maximum brightness all the time, because my eyes get tired very quickly in this case, especially in the evening.
    I saw the other G - Series 17 "notebooks and noticed the same problem.
    Is it possible hardware problem or this is common for Qosmio 17 "poster?

    Hello

    I never heard the show. The fact is that you can change the brightness of the screen on many laptops Toshiba, but I've never heard or seen of wave or nod to the screen. I m not sure if it s only your vision or it s a really a display error (FL-UPS).
    If you are not sure of the fault, then take the unit to your local dealer or contact the service of Toshiba.

  • Screen is blank when Qosmio G20 starts up

    When I turn on my Qosmio G20-110 I hear the usual chimes and on my LCD backlight lights up but nothing else on the screen.

    Any ideas?

    Hello

    Have you plugged an external monitor to the laptop? Maybe it s something wrong with the display internal and so you can see anything on this subject. It s worth a try because you can check this in a few minutes.

    But I guess that it s a hardware problem with the display internal and/or mainboard or something other than your laptop must be verified in professional people, they can disassemble the laptop and exchanging parts of equipment.

    On the Toshiba site, you can search the nearest service provider authorized good luck!

  • Qosmio G20 beep a screen much and dimming - why?

    Sometimes my Qosmio G20 begins beeping very much and reduce the brightness on the screen.
    This happens while it is running on the current and with the option of putting to the highest level.
    Simoultanesly there is some blue lights above the keyboard that will start to blink.
    The only way to stop this behavior is to press the button under the flashing blue light and then go into a control panel handle power settings. To do that I have to change the brightness, press on apply, restore the brightness and press on apply again. After that, it can work for a long time before the next incident.
    I have the latest Windows updates, I have an anti virus installed, and I remove spyware installed, so I don't think that those who are to be suspected.

    This happens usually when the PC play a film, but occasionally, sometimes while I play a game or when I use it for work.

    Any help will be appreciated.

    Hello

    I recommend checking out Toshiba's energy saver.
    Select your power mode and check the action of setting parameters.
    Please check the settings of the alarm level.
    You should take a look also on the basic settings. There, you can control the brightness of the screen.
    Please keep in mind that the device uses patterns of Toshiba power saver in the Windows power options properties.

  • Qosmio G10-133: the blue lines on screen

    To all those who can help you:

    I turned on my Qosmio yesterday to find a series of unwanted blue lines, distorting the Qosmio logo. Lines and distortion continued until the operating system came at the opening of my office. At this point the whole system locked and the screen went completely blank.

    The Qosmio player suffers from the same problem. The boot system, but crashes when the display is asked to do something.

    I can open the operating system in safe mode, but the lines still appear to a lesser extent on the screen.

    I have run all the tests and has been through the manual troubleshooting section. I tried to reinstall the drives and roll back to the previous facility. But, for all that I try, nothing will change.

    Qosmio my friend did exactly the same thing a month or two it is a. Solution from Toshiba was to replace the motherboard.

    My Qosmio is still under warranty, and I am very happy to send it because Toshiba has one of the best customer service I've had to face.

    But, I was wondering if anyone had any ideas?

    Thank you very much.

    Hello

    I also very pleased with the customer support service Toshiba m.
    I think that the simplest and the best way to resolve this weird display problem is to bring the unit to the ASP. Laptop you is guaranteed to be protected and a replacement is free.

  • Qosmio G20 - could not get the video to display on the LCD screen

    I have a laptop Toshiba Qosmio G20, running Windows XP MCE.

    The DVD player on board isn't sounds very well so I thought I would plug an external DVD drive to expand its use. After a lot of internet research, I finally found how to do this. Here's my setup.

    Using the monitor port I used the adapter 3 RCA jacks. (There is no S-video on the DVD drive and an adapter did not work). I finally discovered that in order to get the image on the screen, I have to use Fn + 4. Now, here's where I'm having the problem. I can't get the video to display on my external LCD. FN + 5 didn't do. The monitor is an I - inc AH191D and is connected by VGA cable. There is no driver other than the one for the VISTA operating system... That is why it is not anywhere in the Device Manager.
    Here are the settings I use in order to have all that shows on my desk, shows on the monitor.

    In Control Panel open to the screen. Properties
    Number chosen 1 - multiple monitors GeForce Go6600 video card...
    Advanced under
    the GeForce G06600 tab,
    nViewDisplay Mode: clone 1 a 1 b
    The main screen: digital flat screen
    Secondary display: AH191

    I also tried using the properties of controls on Toshiba. He says under TV output TV output but gives options of the program, but I don't know what I would use. Any ideas out there?

    Wait I'm confused, if you try to send the output of your external DVD drive in the laptop, and then display the image on an external monitor attached to laptop?

    If you use the DVD player on your laptop, it will be good quality S-video as a signal of low resolution.

    Is there something wrong with the DVD player?

    If it's just the DVD software you don't like, you can download other DVD players. PowerDVD is excellent, its better than WinDVD and other players in my opinion.
