Tecra R850 - screen is very low

My screen died last year just lost brightness. I replaced it with a new one, but still no light. If I hold the right way to the light, I can see the very small screen. What could be the problem?

I can't say for sure, but I think that there is a problem with 'background' - FL inverter.

  • Equium A60-181 screen is very low after reconnection of cable

    My satellite had been very slow lately and I was advised to remove the base and clean the dust fan (I'm quite a novice).

    When I replaced the screw, the screen would not work, but all the power lights were on. I reopened the base and found that a wire was disconnected and rested there. After that, the screen went very dark.

    Any ideas what it could be?

    Any help appreciated.

    Hello

    Uh, I think that it s is probably not a good idea to screw on your machine without having experience with mobile systems.

    Thus, for your problem, try to reconnect the cable but correctly. In the case of no success, it would be useful to bring your machine to a technician or at least to an authorized service partner to check your machine/connections. Maybe they can find the error.

  • Portege R600-11b - screen is very low

    Hello

    The screen on my Portege R600-11b disappeared suddenly extremely dim. There is no problem with him coming back to life after hibernation - but he remains coems back extremely dim. Light blinks until when I press the button in the upper right corner with a symbol of the Sun.

    I think I might need a FL inverter? Do you know how do I know which I need and instructions on how to fit it?

    Also I had problems with Windows 7 Professional turning very slowly. I'm assuming that the two problems are not related.

    Hope you can help, thanks.

    Hello

    I recommend connecting an external monitor.
    If the image on the external monitor would be perfect, then your internal screen or inverter maybe FL needs to be replaced.
    You ask how to check this?
    Well, I'm afraid of each part should be checked using another good part tested m.

    In your case I would ask a support specialist
    Guarantee is valid? If yes then I recommend to contact Toshiba service in your country.

  • The screen of very low brightness after a new installation of LED panels

    I recently changed my screen was cracked and paid for it as physical damage are not covered by the warranty of my SVE15136CN. A few days later, the new screen developed a black spot on the left which has increased significantly every day. So I gave him in the center of service again. The service man now says he has changed the screen, but that's a new problem. After the first start, the screen works normally. After a few hours, the brightness is extremely low and not back to normal even after handeling options brightness and power through windows or change the graphics driver. Nor did the change in brightness after plugging in the charger, as it shud be ideally. After three weeks, he suggests that my screen cable is defective not allowing not my screen to win enough power (then how to get enough power to start?) or even the motherboard needs to be repaired for damage. (how it works for the first start?). I feel that something is fishy in this regard. Tell me if it is possible everything that happens? How shud I proceed?

  • Re: Blue screen on Tecra R850-1HU install Win XP Recovery disk

    Hello

    I have a Tecra R850-1HU that comes with windows 7 pro

    I stopped the media recovery for win xp

    The installation is correctly with xp and when I reboot, I see the logo win xp for 1 second and then screen (0x0000007B) Blue

    I try safemode... nothing works

    I have load mini windows xp from a cd and I see all the files on the hard disk from the cd of recovery if it s installed

    I try to put the bios sata to ahci or compatible with the same problem

    I try many times with the same problem on a different machine with the same problem

    The laptop is returned to Toshiba (they have installed win xp from an original cd of microsoft, so I need activation, and I have to do this on 20 computers laptops and good course that no, the toshiba cd creator app, win the dvd...)

    I contact toshiba, I'm not sure that they understand what I want, I got a new dvd of restoration with the same problem

    Anyone has a solution I would be very happy

    Maybe something to change in the bios but I don't know what?

    Thanks for any help

    In General original Toshiba recovery image is tested and should work properly on certain model of laptop. If there is a problem with recovery original you should clarify this with Toshiba directly.
    As far as I know the BIOS should be set to default settings and nothing should be changed in the BIOS settings when you want to use the recovery image.

    All I can imagine is that there is something wrong in the image itself. In the past, I had a similar problem with old Portege 2000.

    Is done: If you want to use the original image you must clarify this with Toshiba. Toshiba must offer good job recovery image. If you want to use own WXP then you must purchase the license for this. Toshiba has nothing to do with the activation of the OS.
    (> I have to do this on 20 computers, laptops and of course not, the toshiba cd soft > creator, win the dvd...)
    How to understand this?

  • What can not run more than 2 screens on my Tecra R850?

    Despite claims that the R850 (with Radeon graphics card) will be 4 screens, the best I can manage is 2. I am trying to connect 2 external LCD screens and continue to use laptop as another screen (3 in total).

    I did a lot of research, and even if I can find a lot of people having the same problem, I can't find an answer. I tried to update the driver but that caused more problems than it solved. I use W7.

    Can someone tell me how to use more than 2 screens on a Tecra R850?

    Thank you.

    > I am trying to connect 2 external LCD screens and continue to use laptop as another screen (3 in total).

    In this case, you will need to use an external device, like the Dynadock

  • Tecra A3 has very low volume

    Hi all, I bought a used Tecra A3. With Win XP Professional, service pack 3. I have not all records with him.
    It was working well before a week or two ago. It has very low volume, I have all levels of volume and the maximum wave. The manual volume knob on the front has no effect, it used to work
    I think the problem started when I downloaded youtube FLV files, then I downloaded a program ('super' was the name of the program) to convert the FLV files into AVI files.
    I uninstalled the program of conversion, I failed to convert anything. I've uninstalled and reinstalled the driver of sound card - card his Realtech AC97. I uninstalled and reinstalled WMP11. None of this has helped.

    On this view, I saw how to do a system restore. I thought to perform the system recovery can solve the problem.
    My question is, if I perform the system recovery, to the GET to the elimination of the parameters of the box, it will clear the WIN XP operating system?

    Thanks for any assistance received, Darren.

    Hello Darren

    Please do not be angry on me, but make you it so complicated. Let's be clear on this:

    Saved on DVD of recovery recovery image contains the operating system, all necessary drivers, Toshiba tools and utilities and some additional applications such as a DVD player. So if you want to install the OS by using Toshiba recovery media will be deleted all content saved on the HDD, formatted partitions and lately OS will be installed. When all is finished you will have clean operating system preinstalled. It will be the same State as the first day after the default purchase.

    Then I don't understand what you mean now with the restore process. During the installation of recovery is complete you must not install or configure anything. Just boot OS, install your favorite software, install the Microsoft updates and be happy.

    If you have any other questions please post again, but please if you ask something to be clear and precise.

  • M40-285: very low contrast on the screen

    Hello;

    I have a new M40-285, and I found the screen with very little contrast. It always happens, even in the BIOS screen.

    On the lower side of the window, there is always a Flash of light, the background is never 'black', more like a gray.

    I got a M30X and the screen was crisp and Nice. That was the reason on the purchase of an M40.

    The laptop is brand new, I ask for a replacement, or something usual in this model? As I said, M30X screen was wonderful!

    Best regards.

    Hi Fran

    Satellite M40 is well-known for me because one of my friends has a. I can't really understand what exactly is going on with your laptop but try it please use the FN + F7 key combination to set the brightness of the screen up.

    If you are not satisfied, please contact your local dealer and check with him. M40 is a very nice unit with a fantastic design and I believe that there is no hardware problem, just a few bad display setting.

    Good bye
