Tecra M3 dark display, checked the usual problems

Hello

My M3 went dark, it flickered on and off for about a week and then completely dark. I still work if I get the right angle and an external monitor is fine.

If haven't tried a new cable from the screen, no difference and a new inverter, also no difference.

Sometimes if I switch between views (Fn + F5) I can get the display works fine, but as soon as the screen is turned off for some reason it won't once again.

I also re-greased the heatsink on the NVidia chip.

And I checked the backlight by plugging a converter working on another laptop.

I have a M1 and there is a relay type sound when something has changed on the screen, I can't remember if the M3 never makes a similar sound, even if I used it for about 5 years.

I also saw that he suggested that he might think that the cover is closed, I don't know how the M3 detects that the lid is closed.

Any suggestion or help would be welcome.

> My M3 went dark, it flickered on and off for about a week and then completely dark. I still work if I get the right angle and an external monitor is fine.

This means that the graphics card chip was Ok, which means that it could be a display problem
I doubt that it ups s related question. If FL inverter would be defective, then you'd see everything on the screen, but everything would be visible behind a thick fog.

Of course, it s that my personal opinion and nobody would be able to tell what dysfunction part without running any hardware, test procedures
Then maybe you should ask a support technician

  • Tecra 9000 - no display on the LCD screen when you turn on

    I recently got a Tecra 9000 for cheap on eBay. I am experienced with the construction and repair of computers, but not so with laptops.

    The problem with this laptop, it's that do not display on the LCD screen when you turn on. It was just black, no backlight, nothing. I took the laptop all share, found no obvious problem. I had to turn it on and the screen lights up a few times trying to figure out the problem. Would it be a bad connection? Or something else?

    After getting it to start work, I'll try to start to put it back together and it stopped working again. I haven't not been able to reduce it to know if it's a bad connection or a card problem.

    Someone at - it suggestions? This is a problem for others here?

    As you describe the issue, I think it is somehow a bad connection or a damaged cable, because it does not work once you have disassembled the screen.
    Maybe you need to check all the cables, leading motherboard to the LCD and take a close look, maybe for a few scratches or strong curvature.

  • Tecra A10 - poor display through the port replicator

    I have an error with one of my clients, they have 3 x Tecra A10 is bought in the last three months, the last time being last week.

    I get a very poor screen through the port replicator, lines running through the screen almost like the lines of scanning, or RF interference. It happens on all three laptop configurations.
    We have new Phillips 19 "wide and 22" widescreen, I also tried a HP 19 "wide where else in the company. also having the same problem. These monitors are working 100% if hooked up to a computer or DIRECTLY into the laptop A10, as soon as you plug them into the cradle we get lines through the screen.

    I'm learning to communicate with the provider in order to replace it, because I have three already do the same thing, I'm pretty sure that I will receive a fourth with the same error.

    Someone else has the same problem?

  • Media Center cascade have not all photos - not the usual problems

    This isn't a matter of marking and refresh. I searched on the net for weeks and I have not found someone with a similar question. Basically the waterfall poster only a fixed number of album covers from A to somewhere through t. tried to add in music by alphabetical order, letter by letter and refresh the cache of art every time, and it always stops updating at the same point. I tried to add music in reverse order of Z back in the same way and I get the same result when I arrive about G.  I guess the cache album_art is limited, but I can't believe that no one else has had the same problem. My music collection is not that the large = about 70 GB / 1200 albums.

    Any help gratefully received.

  • Satellite Pro M10: Display of the strange problem

    I have a M10 Pro of the Satellite with 14 inch display is 6 weeks out of warranty.

    The other day, I got cold room and the display went funny - odd pixels, green and black with small points which then becomes more clear screen so that the entire screen is a mixture of points fluorescent which becomes white and then things come back.

    Then, the cycle repeats itself after a few seconds.

    I perform a restart and everything's going well for a while, and then it restarts. I move the laptop in a cold room and it's ok again. I can't understand that the issue occurs on Windows XP and SUSE 9.0 (although it just hangs). I have run SpyBot, have the latest virus checkers, the update of Windows (SP2) and NVidia drivers.

    Any ideas?

    Seemed to have solved the problem by dismantling the machine, could not do not get all the way and completely remove the top from the bottom as there seems to be a hidden screw. Everything is fine now, could have been the fact that some of the screws were loose.

    Also had a full SpyBot and Virus Check.

    I also had to re - save under a different name, since it is "Specific country" even if I thought that I had, I now have three profiles - two I created recently, and one I could not remember the username for, would be really better if password request tells you the user name to an e-mail address it is registered. It's really hard to keep track of them so I have a lot of connections as a computer scientist. Really really annoying and stupid system.

  • Satellite A660 - display problems, very dark display

    Hello

    I'm at the end of help please.

    I have a Toshiba Satellite A660 PSAW3A-07P00R.

    recently, it has been very, very dark display on the screen, almost impossible to see.
    I tried the following the problem solved.

    1. set the brightness to the MAX in the operating system, power management, etc.
    2 reset the BIOS to default settings.
    3. set the brightness to the MAX on the laptop brightness settings.
    4. check the external display via a VGA cable. tested ok.
    5. I bought a new LED 16 "screen but the new screen has the same problems. If I understand correctly, LED screens (1 data cable video on the bottom of the screen to connect to the motherboard) have the "inverter" built into the display, so appears not to be a problem of map display, brightness or graphics. I would be fair to assume that this is related to the data cable from the screen? If Yes, is a piece that can come from Toshiba? or something easily fixable?

    is there something easy, I missed, or something I have not tried?
    has anyone else experienced this problem and solved?

    Thank you in advance.

    > I would be fair to assume that this is related to the data cable from the screen? If Yes, is a piece that can come from Toshiba? or something easily fixable?

    As much as I know there is no FL inverter then, or you can override the display or the cable (LCD/FL)
    LVDS cable) with a new one and the test shows again.
    I found a compatible: K000103140 LVDS CABLE

    You can see the first color - pure red it seems correct and solid but second it - a small red varation there artifacts / protected by a kind of tasks.

    I learned that it is a problem of dithering that can be set in the BIOS.

    For the Satellite A100-237 the problem has been resolved by downgrading to an older version of bios, but what can I do with my laptop Tecra A7-112? :|

    Have you checked whether the BIOS most recent update has been published on the driver page?

I have looked for help on the local Apple Store and support too, but it did not help. I would like you help me solve this problem.

    Your machine is still under warranty, so you should take it to your local Apple store for repairs. Function late in January, you bought it, you still have phone without support. If you can't find any help on the Apple Store, then I don't know what you expect to find here. We have no way to check for problems you have described or any additional hardware, etc.

  • Tecra M4: Known issues with the display of graphical interfaces user written in Java?

    Hello

    I am developing software in Java which will run on the M4 model and have acquired a M4 to test the application.

    In fact, my GUI looks good when the monitor is in a normal "standing" position. However, when I fold the monitor down and transform all a TabletPC, I see the M4 is an empty JPanel.

    The GUI is written using the swing and consists of JPanels nested with GridBagLayouts.

    I tried to update the OS and my graphics drivers with no luck. First of all I would like to ask if anyone else has experienced similar problems and if so have any suggestions on how to fix?

    My M4 runs the same hardware/software that it came with Toshiba and I use jdk 1.5.

    Kind regards

  • Problems with the display after the update of Windows

    Hi guys,.

    I have not installed or updated all programs on my computer for at least a few weeks, with the exception of Windows Update, so part of MS updates, nothing has changed in recent weeks.

    A few days ago, my computer (HP dm1 laptop computer) screen acted funny - I took a screenshot of what happens and posted here:

    http://DL.dropbox.com/u/1076277/desktop_problem.jpg - basically, the display is all messed up with repetition of lines, etc.

    At first I thought it could be a driver problem, but the drivers are ok and were not being updated - in fact, in addition to the usual updates, the only new was the new update now live.

    I did a system restore (restore a week) and everything seemed normal again - this problem is intermittent, but very frequent, but within a few hours of use, there is no problems - until I run Windows Update, and it all started again...

    Any suggestions as to what might be the cause of the problem and a solution? I don't really have the time now to keep stable each item in the update...

    Thanks for the help.

    Hello

    If you want to study, it will take time but you can find the offending update.

    First update all updates (redundant, uh?).

    Make a note of all of the updates (KB numbers, etc.).

    Restore and install the updates one by one and not simultaneously.

    This way you can find the update 'wrong' and later come to conclusions based on what it is supposed to fix.
