• HP probook 450 G2: flickering horizontal lines on the screen while watching the video after water damage

  Hello

  My father accidentally threw a glass of cola on my computer, on my keyboard. I was able to turn my laptop upside down very quickly and went out of the battery. I then let dry for 24 hours. At first glance the damage seemed limited to my keyboard that I already replaced. Everything else seems to work very well (sound, touchpad, usb ports, hdmi, dvd drive port) until I watched a video. Flickering horizontal lines appeared in the background, which are only slightly visible. Lines do not appear when I'm surfing the internet, playing games, or when I do no matter what other casual stuff. I also don't see any flickering lines when I connect to my laptop to an external display.

  Does anyone have an idea on what the problem might be and what parts can I replace to fix this?

  The unit to boot BIOS and check if you get all the lines. If you don't get all the lines in the BIOS screen,

  then update the BIOS and chipset. But if the problem persists then you must send it to the service.

• HP 15 laptop: flickering horizontal line at the top of the screen

  Hi, I bought this laptop 10 months ago and its been great until about a month ago. A month ago the hard drive doesn't work faster (Super slow r/w) and is noisy. 2 days ago a horizontal line at the top of the screen started flashing when I started the PC. Then I rebooted a few times and nothing. I finally found it flashes only when the pc is unplugged. I loaded 100% and it continues to blink. Update my display drivers did not help either.

  Video: https://www.youtube.com/watch?v=7zJioGvs2Bg

  In the video you can see lines flicker. When he started there was only one, but it has gradually increased to 4 sound at this time. Also, the line crosses the screen completely but is no longer visible to these 4 points.

• Display a flickering horizontal lines. Impossible to do anything.

  When I start my computer I have no way to tell where I am on it.  The computer is running and all of the programs, but the monitor just keeps changing colors and shows nothing.  I have a dell xps 1530 with the nividia graphics card I am connected to my TV right now typing this.  Is this a driver problem?  Update something?

  If its ok with a screen to reactivate that may tend to indicate a problem of monitor, so its unlikely to be a driver or an update

• Dv6 7246us horizontal line on the screen

  Hi all

  I have a DESIRE DV6-7246us, just updated to upgrade to 8.1 WIndows, yesterday, display fell asleep and trampled, I now have a flickering horizontal line at the top of page 1/3 of the screen. It is a single horizontal line that appears to wrap the text what ever he is going through, around the other side of the screen.  windows 8.1 upgrade was completed Monday, and the line began yesterday.  The computer is stock, with a genuine copy of Windows.  Please help I have runa small business, and this computer is invoked daily.

  Thank you

  Hello again,

  I could solve the problem with an updated graphics AMD HD SP60282 driver.  The only horizontal line has disappeared since I updated the driver.  Previously, it did not matter if I rebooted or the monitor kept awake, it never disappeared.  Now everything works as it should.  The driver can be found by searching SP60282 on the HP site.

  Thank you!

• Computer laptop screen flickering and horizontal lines in Inspiron 15r SE 7520

  I have a laptop Dell inspiron 15r is who is 1.1years old (model - 7520). It worked well up to that of a few days. Last week, he began giving a horizontal line of white point at the top of the screen (like that... in white) for the entire width of the screen. Since yesterday, or a similar line began to appear at the bottom too. Two of these online come and go every 2-3 sec. And the screen will jump a little (like 5 pixels or larger) and it will also sometimes shake which makes it difficult to read letters.

  The problem exists everywhere, even in the start screen. In short, when I press power button / stop and screen start showing something problem also begins.

  Today, I plugged an external lcd display via a vga cable and it works fine. No line and no flickering. So I guess that the GPU is ok? What could be the problem? Would be - this contact that loose or something cable laptop computer screen?

  Another question: I got the security, including the protection against accidental damage and stuff for a year. But since I was outside this period, now, what do I do?

  And since I am outside the warranty period anyway is it OK if I open my laptop and try something?

  Help, please!

  If you have found the solution please share with me.

• 15 "MacBook Pro early 2011 screen and use failure, horizontal lines, edges off the coast of the center of the screen

  Hi there-

  recently worked when all of a sudden my screen turned to a variety of 'snow '. After about 2 seconds, he stopped, but the screen was seriously messed up. Horizontal lines apart a few millimeters, but the lines look as if they were moving a little. In addition, the edge of the screen is now near the Center, rather than on the edge of the physical screen. So, there is a black bar halfway in the screen which cut into 2.

  It froze the computer as well, if I pressed the power to restart. It loaded very well through the screen of apple, but as soon as he hit the login screen, he returned to no usable lines. Cannot get back in.

  Anyone that prior experience, or know what I can do to get out of trouble? Looks different from most other 'horizontal' issues I found in searching.

  Photo attached.

  Thanks and best,

  Curt

• Screen flashing horizontal lines after replacing the RAM

  Hello world

  Today, I replaced the original 2 2 GB RAM each with 2 other 4 GB each (Kingston) for better performance.

  I have a Macbook Pro end 2011 15 ", IOS 9.3.1.

  I opened the computer it vacuum cleaner very carefully, with the lowest power and then I removed the two RAM.

  I'm not new, the machine worked perfectly for 20 minutes, then the screen went black (electricity was running in it, I could see some lights on the bottom), I did close it with the button, turn it on and horizontal lines appeared.

  I turn again and nothing has changed. I replaced the new memory with the 'old' and I still have horizontal lines that cross the monitor (white, grey, black).

  Any idea of what is happening and how to fix it?

  Thank you in advance!

  That could be the problem:

  Hello

  I fear that the problem is related to a hardware problem m.
  The internal display is affected or the graphics chip on the motherboard is faulty.
  In both cases the hardware must be replaced
  Therefore, you should get in touch with a partner service is available in your country for this problem
  I hope that your warranty is valid

  Good luck

  Hello

  Connect the external monitor and check if the same lines would be visible on 2nd screen.
  If these lines are not visible, then it means that the internal display may be defective.
  Otherwise, it might be a graphics card problem if line would appear on two screens.

• Satellite P200D-139 screen with horizontal lines

  I have a laptop Toshiba Satellite P200D-139 and the screen no longer works.
  It turns on but the screen is made up of vertical lines, which slowly fade into a black screen.

  I tried on an external monitor and it worked fine, (so probably cannot be a defective/motherboard graphics card). So, I thought that it was likely to be the inverter or the screen itself.
  After trying a new inverter without success, I bought another second hand screen.

  However, the new screen is exactly the same problem with horizontal lines display.
  Sometimes, I catch a partial glimpse of a Vista screensaver for a fraction of a second, but then back to black. I m not a technophobe, so any info would be much appreciated.

  Please help, as he leads me into the wall!

  > I tried on an external monitor and it worked fine, (so probably cannot be a defective/motherboard graphics card). So, I thought that it was likely to be the inverter or the screen itself.

  Right. I think that the problem is related to the display

  > However, the new screen has exactly the same problem with horizontal lines display.
  Well, it might be possible that the second screen is faulty, too that if you bought this as part of the second hand then it might be possible that you bought a screen that is not working properly.

  What to say; It of difficult to say what you should do next. Buy a new screen and check it again? Well, I think that I would visit the next computer repair store and ask for verification of the display.
  I think it's the best solution in your case

• HP Envy 15: Horizontal lines flickering

  Hi,-that someone fell on having a flicker of the horizontal lines on LCD laptop, occupies half of my laptop screen. His travel and see through... in the color purple and green. I'm just watching movies when it started. Someone says the culprit could be the flex cable/Ribbon between the keyboard and display... Thank you

  Hello

  Most likley the problem is going to be caused by either the display was loose or broken, the behind the screen or Backlight Inverter cable.

  The only way to really tell is to take the laptop goes to see. If your warranty and I recommend go back you to HP for repair, otherwise it take a local IT repair shop.

  Thank you very much

• Satellite L830 - horizontal line across the screen

  All new Satellite L830 has a horizontal line across the screen.

  What can be the cause and how can be fixed?

  If the laptop is brand new it back as soon as possible and ask for replacement.
  On this virtual path, it is not easy to say what the problem is here, but it may be related to faulty display, especially if you can see from the first moments when the laptop is turned on.

  Don't try anything. Request a new one. If you can not new, contact the nearest Toshiba service provider and ask for help. They need to exchange the defective part.
