  • Tecra A9 - LCD display very Dim

    Hi all!

    My Tecra A9 age of 4 years has recently developed a problem with the screen. While using it, I heard a zap and the cut screen. He has not worked since. I was able to plug it into an external to continue monitor to use it even if.

    But I found that the screen is not actually dead, its just very dim. If I look closely and shine a torch above, I can see what is on the screen. Which leads to believe me its something to do with the backlight of the LCD screen.

    Also, I checked, and this isn't a problem with the sensor thinks the lid is closed.

    In any case, I would like to know if anyone has an idea on what the problem is specifically? If so, is the kind of problem that I can fix myself or do I need someone from Toshiba to do for me?

    Thank you!

    Hi Matt89,

    I agree with Akuma. If an external monitor works, it looks like that the FL inverter is faulty. This inverter controls the backlight of the internal display and even it would be defective you can see the picture but very very dark.

    If think the best would contact an authorized service provider. Guys can order a FL original inverter which is compatible and replaces it for you because the screen itself must be dismantled, and that's not easy.

    If your laptop isn't under warranty gift more worry because FL inverter is not so expensive. :)

  • very brilliant screen - is no longer an option?

    I went on the order of lenovo site to recalculate a unit with the superbright screen option. I can't find this selection anywhere. The only choice is the multitouch or standard LED WXGA Panel.

    Lenovo puts is no longer very bright screens with the Tablet?

    It is likely that the outside views are rare and were fired from the site in order to minimize the suffering.

    you might find one pre-configured or TopSeller model with external display that meets your needs.   many dealers in the United States have them in stock and ready to ship.   Download the last leaves PSREF here, find the type of machine and model you want and search online for this issue.

  • N200 0769 - screen very Dim/Dark

    The screen on my N200 went very dark (it can do about a few details) when I turned it on today. I'm guessing that the backlight or inverter went. Looked at the maintenance manual to find the RUF, but there are three options for my model and I don't know which search or if they had all work in theory; SEY - 41R7701, TDK - 41W1392 and Sumida - 41R7702. Any advice on where to go, or what to try? Thanks in advance.

  • Equium P300-16 t - very dark screen

    Hello

    I have a Toshiba Equium P300-16 t, but the LCD is very low
    I see about the office, works fine on an external display.

    I tested the LCD on another laptop and works OK,
    I also replaced the inverter and flex cable but still no luck

    The GPU would have gone?

    > I see about the office, works fine on an external display.
    To me, it's proof that GPU must be OK.
    When you start your laptop is the faint display even when you see Toshiba welcome screen or enter the BIOS settings?

  • Satellite A200-1AX: Win7 has very limited screen resolution

    ?:| Can someone help me please?

    I have a SCREEN RESOLUTION (1280 x 800) after that I went to w7, before I can get about 1600 x 1280 when I was in very limited vista. I lost my vista recovery disk so I decided to go with w7, but after that I did some installations/updates to update for all my drivers again my screen resolution gives me the size 1280 x 800 maximum.
    Anyone? Please? I need your suggestions...

    -J' have a Satellite A200 1AX (recently moved from vista to w7)
    -Screen: 15.4 "
    -My graphics card is ATI Mobility Radeon HD2600.
    -I just downloaded the latest driver from ATI.

    Please tell me what I'll do.
    Thanks in advance guys...: D
    Jeje

    > Until I can get around 1600 x 1280 when I was in vista
    I can't believe that why?
    Because the screen internal 15.4 "WIDE XGA supports a maximum resolution of 1280 x 800.
    Max which is possible on the internal display, and as a result, you will not be able to choose a higher resolution on the internal display.

    The resolution of the external display may be higher but not the resolution of the screen internal.

  • The display is very Dim on the 4070CDS Satellite

    I have a Satellite 4070CDS running Windows 2000 prof, full battery, it worked very good alllways, and next day the brightness is very low, that I hardly see what is on display.
    How can I solve this problem?

    Hello

    First of all, I think you should check the settings with the brightness of the screen.
    Check if there is possibility to use the FN + F7 key combination to change the brightness of the screen.
    But if all the parameters set correctly then I guess there is something wrong with the inverter FL. In this case, you should ask the control from laptop service.

  • Satellite P10-304: very dark screen with negative colors

    I have a SP10-304.
    One day I swithched turn it on and the LCD display seems negative like a photographic negative.
    It is very dark, but the colors are there just upside? I connected to an external monitor to the rear exit and it worked well.

    The backlight of the screen seems to be bright enough so I guess that it may need a replacement LCD screen.

    If anyone can help...

    Concerning
    Paul

    Hello

    If you are a lucky man, you won't need to replace the LCD view screen but only the inverter FL. The screen is more expensive laptop parts and it would be very unfortunate if the LCD would malfunction.

    To me, it sounds like a fault of FL-inverter and this part is not very expensive.
    I guess to contact the technician to change this part if you have no experience.

  • Very dark screen of the Satellite L300-1FJ

    Hello

    I have a problem with LCD display on my Satellite L300-1FJ.
    It is very dark. At startup, I hardly see what is on the screen.

    I tried to increase the brightness, but it doesn't seem to work.

    Hello

    You mean you cannot increase the screen brightness by pressing FN + F7?

    Well, I think that the FL inverter is faulty.

    If the FL inverter starts to malfunction so everything on the screen will appear like behind a thick fog.
    In most cases, the FL inverter needs to be replaced.

    So contact the ASP technician in your country and ask for help!

    Good bye

  • Satellite L30 - very small screen

    I have a problem with my Satelltie L30.
    Tour now and very low on-screen display. I tried to make clear checked settings done system restore, but no luck.
    Plugged into the external monitor and I tried reinstalling of Windows Vista Basic recovery disk seems to work.
    The first screen of the time on external screen then nothing happens now. Does not start in safe mode as installation is not complete, but cannot complete cos no image on the laptop screen or external monitor.

    Very confused, any help appreciated

    Just read another thread that this could be a problem with the converter of FL. I was wondering if that could be the case.
    I've only had the laptop 16 months and is now out of warranty. I got bored so prob from the outset and would like to know what approximate cost of compensation would be.

    Thank you very much

    Hello

    This problem could be related to a faulty inverter of FL
    It is a very small part behind the screen
    If the replacement procedure is really delicate and must be performed by a technician for laptop.

    Here's what a real Council alone. You must contact the ASP in your country for assistance.
    Guys should check and if necessary should replace the defective part.

  • Very Fragile screen?

    I've had my Razr Maxx for 28 days. Yesterday morning, I woke up to find it on my bedside table where I left it, but he had 3 cracks inside. He was not charging, it was so that he got hot and the battery expanded and broke it. It does not fall, it wasn't the screen ridiculously easily broken minimal trauma causing him. I thought it was very strange, so I began to google for an answer and I found one forum very interesting with dozens and dozens of others claiming the same thing.

    http://www.relaxing-fun.com/Android/droid-RAZR-Maxx-broken-screen/1938

    I called Verizon and Motorola, who have both said that they have "no known issues" at the moment. How many complaints does take to make an issue of "known"? They told me that there is no option for free repair or replacement.

    I got the original razr flip, another I can't remember, devour<-- what="" a="" joke,="" droid="" pro=""><-- replaced="" 4="" times="" in="" as="" many="" months="" with="" technical="" problems,="" droid="" x2=""><-- awesome="" phone="" and="" now="" the="" razr="">

    This will be my last Motorola phone unless they make it right. I heard a lot about the iphone but always preferred the Android OS. But what does the software if the hardware jump? The Samsung is perhaps my next pick?

    Anyone else who has this problem or would like to send any suggestions or comments, I appreciate it.
