My laptop screen has many white glitches blink all over the screen
I am writing to you in hopes that you might have a solution to my laptop problem. I have had my laptop for a little over 2 years and in the past it had a problem with a “defective dc in jack” while under warranty. But of course more problems conveniently arose after the warranty expired: it has shut down randomly before, so now I keep a fan behind it and it hasn’t shut down in a long time, but most recently my laptop screen has had many white glitches blink all over the screen. The first time it happened, after a few minutes of small white glitches, a big colorful glitch appeared and then my whole screen went black. So now I can use my computer for 45 minutes tops before the many white glitches blink all over my screen and I just turn off my computer before it goes black and turns off on its own. Do you know of any solutions to fix this? I am so disappointed and upset and don’t want the money I spent on this laptop to go down the drain. Thank You!
Most likely the laptop shut downs are related to a clogged heatsink and you would be able to fix the problem if you clean up the heatsink. You can blow off the heatsink using an air compressor or you can take the laptop apart (for people with laptop repair experiance) and remove the dust. I covered laptop overheating problem in more details here.
Now about white glitches on the screen. I think it might be a heat related issue because the white glitches appear after you run the laptop for some time (it’s getting hot). As you mentioned above, after that the laptop shuts down – it’s also an indication of overheating. Not sure though, it’s just a guess.
Connect an external monitor and start the laptop. Set the laptop to output video on both screens and wait for the white glitches to appear. Do you see the glitches on both screens or only on the laptop LCD? If both screens have glitches, then it might be a system board related problem.
If the glitches appear only on the internal LCD screen, then it’s not related to the heat and it might indicate the problem with the video cable or the screen itself.
One more thing. Access the BIOS setup screen and check if you are getting the white glitches even before Windows is loaded. If the laptop has normal video when you are in setup mode but malfunctions in Windows, then it might be just a software related issue. Let me know how it goes.

Hi I have a toshiba laptop and it’s been handled with care most of the time…the only time I dropped it was about a month ago but everything was fine. Just a couple days ago i moved the screen back a little to adjust to how i was sitting and these white horizontal lines sprang across the screen and when i moved it back to how it was it would be fine. so basically i tried not to move the screen. but lately it’s been getting a lot worse meaning that those white lines will come up if the laptop screen is even slighty moved from its original postition and the screen starts fading into a circuit city logo with purple clouds and some writing. I usually press ad hold the power button or restart it after having closed it and left it to be for a while. This laptop is only about 3 months old and I really cannoy afford a new one at the moment so it’s crucial for me to know if this is fixable…thanks!

I just replaced my Toshiba Satellite P-35 LCD Screen. When I boot up the display is fine, but sometimes after displaying the windows (XP)logo (at the sign in screen)start blinking. If I change the settings in the monitor (resolution) stops blinking. Also if I shotdown the laptop, take the battery off, wait for 1 minute, and restart again, everything is fine. Please help.

Hi,
Well my notebook is an HP Pavilion. I’ve been having similar problems with the screen glitch with white lines and black spaces in between almost resembling a channel not clear on a TV. When I took it to get fix… surprise, surprise, it wouldn’t do it for the technician but he suggested it was the cable which would cost me around 300 dollars to fix and told me it probably wasn’t worth it and to keep using my computer until the cable completely busted and use a monitor after. Up until today… I agreed with this. But today.. the screen when crazy. I adjusted the screen which didn’t help and when I went to restart my computer looking for a solution it stopped. The technician said there was no error logged on the computer pertaining to an internal error but why would restarting the computer fix the problem? Especially when I didn’t do anything to affect the cable only restarted?

I have an Acer TravelMate5720 the LCD Screen is cracked so its showing nothing trying to hook up a desktop external monitor it starts up but when it gets to the icon desktop screen it doesn’t show on the external monitor but if i put it in safe mode the icon desktop shows. My function and F5 keys to disable my laptop screen and enable my desktop monitor doesn’t work either. Why does it do this and what can I do to fix it?

I have a problem with my laptop, an IBM Thinkpad R50.
For the past couple of days, there’s this thin, dotted line that keeps running vertically through my desktop all the time. It keeps changing colours, usually varying between red, green, pink and white.
It starts even before windows is loaded.
Help!

Amit,
I’m pretty sure this is LCD related problem. You’ll have to replace the screen. Does it look like this screen?

Hello,
I have a toshiba p35 Satellite 17″ laptop.
As soon as i boot up the laptop, there is a one inch wide white bar running from top to bottom in the middle of the screen. It stays all over from the bootup till i switch off my laptop.
Please let me know how i need to proceed to get this problem resolved. Is it a problem with LCD or some video cable.
Thanks
Amit.

I have a Dell latitude laptop cs600, I also have an R/C helicopter equiped with a wireless camera. What I’d like to try and do is hookup a receiver with A/V jack’s for the wireless camera so my laptop can record the images the camera capture’s but I’m lost in how to go about doing it. I know it has an s-video but I’m not sure how to go about doing it if it’s even possible that way? Any type of advice or if you ned more of a better description please email me Hornet2180@yahoo.com thank’s again…

Griffin,
If the bar is transparent and you still can see desktop icons through the bar, then your problem is related to the LCD screen. You’ll have to replace the LCD or use the laptop as is.
May 5th, 2008 at 3:02 pm
It is transparent, but I have not plugged it in to another monitor.
If the bar doesn’t appear on my TV if I plug my laptop into it, though, it’ll make the job much more difficult-
I’ll have to pry open my laptop, see if there’s something wrong with the video card, pry open my screen,
probably have to buy a new screen, video card, etc.!
Although i’ll probably just adapt to enjoy the bar.
Also: It used to be tinted a light gray, but a couple days ago, I skipped a disc check and it turned
ugly yellow.
May 5th, 2008 at 1:34 pm
Griffin,
Did you test your laptop with an external monitor? Do you know if video on the external screen is fine or you see the same yellow bar?
Is the yellow bar transparent and you can see image through the bar?
May 4th, 2008 at 4:19 pm
I have an Acer laptop, and I have an ugly yellow bar at the side of my screen. Does anyone know a “cure” for this? I’m a computer expert myself, and I know nothing of this type of hideous bar.

My laptop works fine as long as I don’t move it. If I move it the least little bit the display freaks out and gets vertical lines in it. The first time it happened it looked like a giant bar code with black and white vertical lines, but it changes to vertical colored dotted lines or multi colored vertical lines. If I lift on one corner of the laptop the display changes from one kind of vertical line to another. If I hold the down the on / off button down for 10 seconds or so the laptop turns off. Most of the time it will turn back on and work properly until I move it again. Then the display freaks out again. I tried hooking up an external monitor to it and I get the same vertical lines as the laptop display. I also tried going to the CMOS mode before windows loads and it des the same thing. It will do it even if I don’t move it after it warms up. I might get it to run for about 10 minutes without touching it. I lifted the keypad off and used the eraser end of a pencil to gently press on the motherboard and components and the display freaks out. I believe it is a problem with the motherboard. It seems to react more when pressing on the IC chip directly under the modem. I think that may be the video controller. I am thinking it may be a cold solder joint or a crack or something in the motherboard. How can I go about getting this repaired? Is it repairable or time for a motherboard replacement?

I have a acer laptop and i ended up with a back door trojan virus. I used a spyware program to get rid of the trojan and it worked but now sometimes my screen goes white and I have to reboot it. Can it be fix? What can I do?

I have Acer Aspire 5002.The problem is that it shut down randomly at any moment.When I starts it, it starts nomally but while working it shut off randomly.The problem increases when I tried to install Windows XP on it and the condition is that I am not able to install the OS on it.
September 18th, 2007 at 10:44 pm
Osasa,
If the video chip is integrated into the motherboard, you cannot replace it. You’ll have to replace the whole motherboard.
If the video chip is located on a discrete video card, you’ll have to replace the video card.
There is no easy workaround for this problem.

Hi,
