Satellite M30-853 - vertical white lines or black spots on the screen

Hello

I have a laptop Toshiba Satellite M30 - 853 during nearly four years. A few days already, I'm having a problem that they come from the white lines vertical or black spots or screen is smear when I am trying to move a window from time to time. My wireless adapter is in use.

The vicinity of processor, video card and wireless network card are very hot. My cooling fan is starting and stopping, but I'm not sure of its effectiveness.

I disassembled the laptop to clean it if there is little to dust, but I found it in very good condition. Anyway, the problem persists and I am looking for decision. Someone told me that probably that's because of the defective video card memory. It's strange to me because the problem is not permanent it is often and if I try to cool the surface it disappears.

I'd appreciate any suggestions.

In my opinion, these issues must be verified correctly. This can be done using different diagnostic tools. It is important to know what the problem cases.
Of course, it has something to do with the temperature of material and graphics card. Sorry but I'm really skeptical, you can do something alone. Maybe you should seek professional help.

  • Satellite M65-S9063 - vertical white lines appearing at the bottom of the screen!

    Hi all - ideas...

    Model M65-S9063 about 3 weeks ago a white vertical line appeared to the bottom of the screen, it's around a mil thick.

    Then yesterday a second is appeared, a little thinner this time. They are still there even after a reboot! It does not appear that any video is displayed as they are always white. I was wondering maybe graphics card? Or maybe the LCD itself?

    Has anyone seen this before?

    Thank you very much

    Hello!

    You simply determine the reason for this question. Connect an external monitor to the laptop and see what happens.
    If you see the same error on the external display, it s a map or graphic display driver problem. If you don t have this problem on the external screen, you must go to an authorized service provider to swap the internal display.

    If you use a driver display Toshiba not you must remove it and test it with Toshiba drivers.

    I hope I could help a bit.

    Good bye

    Model: C70 - A - 16 L

    Yesterday I noticed a vertical white line on the right side of the screen, running from the top to the bottom, this morning there are 3 lines about 1 cm apart.

    This may be the cause?

    The lines are all located above the powerbutton on the screen that they do no when go further I move the screen.
    Laptop was purchased in April

    These lines are visible on the 2nd external monitor?
    If not, then the graphics card is OK and your internal monitor seems to be affected.

    I think that in this case that the display needs to be replaced.

    A jpg still print with white lines spaced, but I replaced the color cart. Please notify. Thanks in advance.

    Hello

    That's what I feared. This kind of banding appears in images when using normal paper for use with low quality settings. You can try to increase the quality of the prints or try using photo paper.

    A good document to make booklets with photos is the HP brochure and flyer. (C6818A)

    When it is over an unselected path or shape (as in, something that you can select if you click right here), it shows a black box. When you're not selected anchor, it shows a white box.

    The very low vertical lines are coming up on the screen in 4 or 5 places on my KDL-65HX925. Sony India assistance team is subscript, but to change the Panel also did not help.

    Now the expensive game is with the service center for over a week and they refuse to return the whole and execution of R & D with no idea. In India, it is better not to go for the set bonus from Sony because they are not able to provide support.

    But people do you have any idea what is the cause?

  • Black finger across the screen to the bottom only in locked mode - retina 2014

    Mine is a MacBook Pro (retina, 15 inches, mi 2014) 2.2 GHz with integrated display. When I opened the laptop this morning, I was welcomed by a screen locked and noticed a black spot on the lower part of the screen. My heart sank for a moment, but when I logged in, I did not notice the finger any longer.

    I see the black spot that looks like an ink spot (see photo) when I get back to screen locked again. What is an LCD failure or is there something else going on? If it's an LCD has failed, why not see the problem when it is unlocked? How to fix? Thanks for any help.

    Notice the black spot. The white point at the bottom left of the screen above is just the cursor hidden.

    No stain when unlocked can be exceeded.

    Could be a hardware failure.  If you bought AppleCare, you have 3 years warranty on the material and can diagnose the Genius Bar it repair free of charge - it is reproducible, so you can show them.

    How can I fix black spots on the camera in my iPhone 6 Plus? Please help me.

    You see the same locations if you take a picture out in the open?

    It's more like flares of the lens, because of the light coming from one side of the room and hit the lens at an angle. If so, it is an optical phenomenon and cannot be resolved.

  • Tecra M4 - black spots behind the display Tablet cover

    After an intense action of cleaning every month, I recognized a few black dots on the back side of the front glass of the tablet. I did some checking of finger on the screen to see if it's a pixel error. I can say with any doubt that he is not a pixel error.

    After a Google search I found people describing the same. It is assumed that it is the result of fan heavy work.

    Y at - it no support out there that can help me solve this problem?

    Hello

    I put t really understand the link between the black dots on the screen and the heavy work module cooling.
    For me this internet s nonsense provides a lot of information useful but also very stupid gossips, myths and stories

    Always it is that you have a few black pixels on the TFT display and it sounds like a hardware problem.
    So in this case, there is only one solution; This part is replaced or repaired I guess, it should be replaced

    For all replacements, you will need to contact the ASP in your country. Ask them to help and managing others.

    Good bye
