Satellite C50D-A-138 backlight does not

Hi, I have a major problem with my laptop. The backlight of the display will not work. I can see only vaguely the image. I tried to adjust BRIGHTNESS, no joy. It displays very well to a monitor. I tried to replace the screen and Ribbon connection, but the question always arises. Does anyone have any ideas? I am at a loss.

Hello

Connect the external monitor if the same display problem appears on the external display and check.
Where everything seems properly on the external monitor, the problem must be the internal display panel.

The laptop display panel seems to use a backlight LED as the light source.
So probably the backlight of the screen does not work correctly. In this case, the display board must be replaced.

You must ensure that you use the Panel compatible because many laptop displays different support technology (TFT panels without backlight and display supporting the backlight as the construction of a C50D-a)

  • Satellite C50D-A-138 - can't access Internet through IE

    Hello world!

    I'm not too IT literate so need to pick up some brains!

    My partner has just bought a new laptop, Toshiba Satellite C50D-A-138.
    Everything worked very well, the kids have been on it more than him!

    A day has started up as usual, tried to access internet through Explorer with no luck.
    Wireless is on, the connection is our broadband.
    The address is *http:toshiba13.msn.com/?=TEJB*
    I tried to change on google and various other site with no luck.

    I am totally baffled by this one so any help would be welcome.

    Thanks in advance!

    Hello

    The address you mentioned leads to the page of msn.
    I guess you are trying to connect to the internet using the WiFi connection.
    What happens if you connect the laptop to the router using the LAN cable?

    Do you have problems using other browsers such as Chrome or Firefox?

  • Portege R600 - Windows 7 switch backlight does not

    I have a new Portege R600, comes with Windows 7 32 bit and the switch on / off for the backlight does not work.
    I installed the new VFR package, until I uninstalled the old. Also the latest version of the Bios.

    Use the support Toshiba button and placed in the file backlight.exe, still does not work. If I tap the backlight.exe file manually, it works.
    It is not a problem of material, as told in the hard drive of my old R600 with XP Professional and works of button.

    What can I do?
    Toshiba support is not able to help, to talk about the new facility, but is the original unchanged.
    Maybe in the button holder, I put in an option in the empty file?

    > Switch on / off the backlight does not work.
    AFAIK some BIOS versions contains the additional option to enable and disable the lighting.
    Please check if the lighting is not disabled in the BIOS.

    I also searched this forum for some tips and found this thread:

    Hello

    > This problem start after a storm in my area some time ago.

    Because other devices don't work properly and because procedure didn t get it back help you solve this problem, I think that the problem is related to the hardware malfunction possibly that the motherboard was hit by lightning, which would explain the problems

    I think you should ask the maintainer authorized Toshiba in your country to check the motherboard.

    But in my opinion, that the warranty does not cover the issues of environmental impact maybe your household insurance could help you

  • Tecra A4: Display backlight does not work

    Hi all

    Thank you for taking the time to read this. I came across a dilemma. My sister laptop screen broke (baby) and it was far from always being in warranty and we had not assured him. So I bought a new screen for it and it mounted fine. When I turn on the laptop, I can hardly do anything on the screen as if the backlight does not work.

    I see that it is there, it's just very very dark. I thought this would be a problem with the inverter. So I bought a new one of those too, but alas, it still does not. I can do all things beautiful to display on an external monitor via the VGA port.

    Someone at - it ideas?

    Thank you once again

    Hello

    I understand you want to save money, but especially help the technician is most recommended as repair by yourself.
    In any case, as mentioned, you should be sure that the cable has been connected in the right way.
    You must connect the LCD/FL cable to connector LCD/FLand connect the cable to connector HV HT. Place the module LCD, the FL inverter board in the correct position.

    Good luck!

  • Backlight does not turn on more Satellite M70 147

    Hello outhere.

    The backlight on my M70-147 M-series lights no more.
    First of all, I noticed that when the awakening of the laptop from the standby or hibernation mode.

    At first I thought that the screen did no more work, but when I looked closely I could still do believe the icons on the desktop remotely. So, initially, I rebooted the laptop and then most of the time the backlight will light and stay on.

    But now he did not do more, not even when I close the screen (to force the standby mode) and then open it again, the backlight won't turn on.

    I also looked at other forums and topics, what the cause could be a faulty inverter or a broken rear window.

    So can anyone with the symptoms described tell me what could be the cause?
    I am sure that everything goes well with the graphics card because when I hung on my laptop to my LCD of dads he just showed the Office from my laptop on the LCD display. Also the first time I did it after pressing Fn + F5 several times the screen of my laptop would come on a few times. But now it does not more.

    So can anyone with the symptoms described tell me what could be the cause?

    Thank you very much.

    > Can then anyone with the symptoms described tell me what could be the cause?

    For me, it looks like a faulty FL inverter.
    The FL inverter is a small part behind the frame of the screen and it controls the backlight.

    Usually the external monitor should work fine because the FL inverter affects the internal display only...
    However, the problem can be solved by the replacement of this part.

    I recommend you contact the Toshiba ASP in your country to get this part replaced

  • Satellite L500 1QK - output HDMI does not work with a Toshiba DVD player?

    Hello

    Why Toshiba DVD player does not work when I plug the HDMI out on my other bigger screen...

    While he plays well the DVD on the computer and, if I can get the signal HDMI OUT with VLC playing other video formats...

    I hope there is a way to unlock this, because I prefer to play DVDs on my computer (for his problem because I have the ear is not good)

    Thank you in advance for your help, if you can.

    Kind regards.

    Hello

    To be honest I n don't know 100% what your problem is.
    If you want to watch DVD movies on your computer with the help of a reader DVD Toshiba but the captain must be indicated on the external screen follow these steps:

    When you have connected the HDMI cable (other) outside on the screen, use FN + F5 and switch to the external display only. When you see the desktop on the beginning of the display external Toshiba DVD player and I think that everything should be OK.
