There are a lot of reasons why there are horizontal or vertical lines on the computer screen display in Windows 10. To solve the horizontal or vertical lines across your desktop or laptop screen issue, you may need to find out what cause the problem.

The horizontal or vertical lines on the computer screen may be caused by various issues, ranging from outdated graphics card drivers, incorrect video cable connections to defective ribbon cables. You could enter the BIOS settings to determine whether it is a software-related or hardware-related problem.

Since BIOS is not a part of the Windows 10 operating system, if you still see horizontal or vertical lines on the computer screen, it indicates that it is software-related. If you see no horizontal or vertical lines on your computer display in Windows 10, it tells that it is related to the hardware.

There are six recommended methods to fix horizontal or vertical lines on the computer screen in Windows 10, applied to any screen like Dell, Samsung, HP, Lenovo, LG, Acer, etc..

If you notice horizontal or vertical lines on the computer screen in Windows 10, it may be caused by the incorrect video cable connection. You can try to reconnect the video cable to the screen and then check whether the horizontal or vertical lines are gone.

If your ribbon cable is defective, the horizontal or vertical lines will show on the computer screen in Windows 10. You could replace the ribbon cable with a new one of the same connection type to check whether the horizontal or vertical lines still exist on your computer screen.

Once it is proved that the horizontal or vertical lines on the computer screen in Windows 10 are software-related, the most possible culprit is the outdated graphics card driver. You shall upgrade it to the latest version to solve the driver compatibility problem. To do this, you can update the Display driver from Device Manager manually and check if it helps, which will take a long period of time.

Incorrect screen resolution settings can also result in the horizontal or vertical lines on the computer screen in Windows 10. To get rid of the horizontal or vertical lines across your display, you need to adjust the screen resolution settings. Follow these steps:

Step 4. A lot of screen resolutions will be available to you. Set the resolution drop-down menu to the setting that has the (Recommended) text next to it and click OK.

For any other Windows 10-related issues, such asblack screen, no Wi-Fi available, stuck in a reboot loop and more, welcome to check out the Windows 10 Issues and Fix section.

The appearance of static or flickering horizontal lines on a computer screen can be frustrating and inconvenient, but there are many steps you can take to try to fix your problem. This guide will walk you through various checks and fixes you can perform on your computer and its monitor to find out why the lines are appearing and what to do to make them disappear.

Horizontal lines on a computer monitor can be caused by overheating or physical damage to the monitor and connecting cables. Conflicts between the screen and selected screen resolution and refresh rate settings can also cause line problems, as can out-of-date device drivers and operating systems.

Try a different monitor. If possible, try connecting to a different monitor or screen. It can help you determine if the lines are caused by your computer’s screen or the computer itself.

Check your monitor while it’s disconnected. Keep your monitor powered on, unplug it from your computer, and look for any flickering or lines on its screen while it’s disconnected. If you see any kind of distortion, this means that your monitor is damaged.

Close and reopen your laptop. Close your laptop’s screen, wait a few seconds, and reopen it again slowly. Look to see when the lines begin to appear on the screen as you open the laptop. If the lines only occur at a certain angle, the cause is likely damaged wiring.

Check the monitor connection. Ensure all of the cables are securely connected, and watch for any improvements in screen image quality while you’re inspecting the cables. If you notice the image improves or worsens while touching the connecting cable, it may need replacement.

Remove magnets and electronics. If you have other electronics or magnetic devices near your computer, screen, or the connecting cables, move them somewhere else as they may interfere with the connection and cause the lines.

Reset your monitor to its factory settings. If you’re using an external monitor or screen, use its built-in settings, not your computer’s settings, to reset it to its factory settings. You can usually access these settings via a physical Settings or Menu button on the computer monitor itself.

To fix coloration and distortion on a computer screen, power the monitor on and off, restart the computer, and make sure the cable between the monitor and computer is connected securely. If you"re using a CRT screen, try degaussing the monitor. You can also try adjusting your video card"s quality settings and experimenting with your monitor"s adjustment buttons.

To fix screen burn on a monitor, also called "ghosting," try turning off your display, ideally for at least 48 hours. Also, try setting your screensaver to an all-white image and letting it run for a few hours. You can also try using the JScreenFix tool, which fixes stuck pixels.

In a laptop, the screen is connected using an LVDS or eDP interface, and these just transfer a series of pixel for the screen over and over again, not caring about lines.

Artifacts like bright colored horizontal or vertical lines appear when either the flex cable from the LCD screen IC gets bad connection to the LCD glass or when the glass is chipped or cracked outside the visible area. Then the IC can no longer drive specific column and row conductors to the pixels and the pixels remain either lit or dark.

Another possibility is that the power supply powering the LCD module, including the LCD IC is not providing stable enough power due to deteriorated capacitors. This could explain some horizontal lines, but these lines wouldn"t be solid and would be changing depending on the screen content.

This problem occurs because of a hardware limitation that is known as "tearing." Tearing is a video artifact in which the top portion of the screen shows a different frame of video than the bottom portion. This is more noticeable during scenes that contain fast motion. There may be a noticeable horizontal line at the point where the two frames meet.

If you experience noticeable cut lines or tearing, and not only when you play a DVD movie, the display may be configured to a refresh rate that one of your monitors does not support. If this is the case, you can resolve the issue by configuring the display to a refresh rate that is supported by all monitors.

Multiple factors can attribute to horizontal lines on laptop screen. This post will explore the possible causes for monitor horizontal lines on computer and then provide you the guide on how to fix horizontal lines on laptop screen. MiniTool offers you the details in this guide.

Elements like outdated graphics driver, wrong video cable connection, improper screen resolution, and other factors can cause the horizontal lines on laptop screen. Well, you can fix the issue with the following methods.

The horizontal lines on laptop screen might be associated with the incorrect video cable connection. So, you should try reconnecting the video cable to the monitor to resolve the horizontal lines on laptop HP issue after it appears.

Wrong screen resolution is responsible for the vertical or horizontal lines on laptop screen HP issue. Hence, you can try changing screen resolution to troubleshoot the error. Here is the guide for you.

Outdated drivers can result in various errors like Graphics Device Driver Error Code 43, Esc key not working, MHW graphics device crashed, and so forth. It is possible that the horizontal lines on laptop screen issue is also triggered by outdated driver.

Step 3: In the next window, choose a driver update method based on your demand. You can update the graphics driver either automatically or manually. Then follow the on-screen instruction to finish the process.

The Windows built-in program – Display Quality Troubleshooter, is also helpful for fixing monitor horizontal lines. You can run it by following the steps below.

If you still see horizontal line on laptop after trying the above methods, perform a clean boot. If monitor works properly in clean boot, it indicates that something interferes with displays. Then you should remove it manually.

Step 5: Click on OK in the System Configuration window and then reboot your computer. If your computer displays normally, enable the programs that you’ve disabled one by one until you see the horizontal line on laptop screen again. Then remove that program manually.

It starts off as just a little grey fade, but as i use the computer for several hours, it gets pitch black and grows in size, reaching about 6-7 mm in “thickness” along the vertical of the display. Needless to say it stretches entirely horizontally. If i leave the computer in idle or off for a few hours or overnight the line goes away, only to come back progressively after a couple of hours of use the next morning.

The line is just like the other reports, it doesn’t “hide the cursor”, it still kind of sort of shows content and it goes back to normal as the computer cools down, so I don’t think it’s dead pixels. As the hours passes it gets to “weird colours and text retention”, for example the address bar of Safari stays in the black area for a bit even if I switch to another app. Luckily (knocking on wood) the “damage” doesn’t seem to be spreading, or it’s doing so very very slowly. I now use the notebook’s own display the less time i can, relying mainly on my primary HDMI monitor, but still, my workflow needs multiple hours of dual-screen action each day.

Side question for you all: i also wanted to replace my thermal paste (actually came on iFixit to look for a “don’t mix up the screws” guide and found this thread in the process) to improve temps a bit, since we all know Apple loves to put crappy rock hard thermal compound in its thousands dollar machines…my warranty as said has already expired, last and only time the computer was opened was July 2019 for a warranty-covered battery and keyboard replacement (luckily that was a recall). Do you think that by opening it up myself i risk "upsetting” Apple even more when i’ll bring it in to try and get the screen replaced, and I’d better do it afterwards? Or since the machine is out of warranty anyway i shouldn’t care? Since i already know they’ll try to negate any responsibility for the screen defect, I don’t wanna give them the easy excuse of “someone else opened it and broke it”.

Computer screen, like any component of a computer, may fail to work. Today in this post from MiniTool, the topic – vertical lines on monitor will be discussed. What causes vertical lines on computer monitor? How to troubleshoot this issue? You can get the answers after reading this article.

When using your computer, you may find the monitor or computer screen isn’t working properly, for example, monitor not displaying a full screen that has been talked about in our previous post. Additionally, you may encounter another issue: your computer screen has lines running through it in Windows 10/8/7.

What causes vertical lines on computer monitor? Lines on computer screen can be triggered by various issues including outdated graphics card driver, defective ribbon cables, incorrect video cable connections, damage of the screen, etc.

The main reason for computer vertical lines may be the outdated or incompatible graphics card driver. To fix this issue, it is quite easy and you only need to update the driver.

Incorrect screen resolution setting may result in vertical lines on computer screen in Windows 7/8/10. So you can try adjusting the setting to get rid of the trouble.

You can try turning your PC off and unplug all peripherals. If you are using a laptop, you can flip it upside down and slide the battery release latch to take the battery out. Then, clear all residual power by pressing and holding the power button for 15 or 20 seconds.

As mentioned above, the vertical lines on monitor can be related to the incorrect video cable connection. To fix this issue, you can reconnect the video cable to the screen and check if the lines are gone.

Sometimes lines on monitor may be related to the ribbon cable that connects your laptop’s screen to its motherboard. The cable may be worn out and even crack over time.

Are there vertical lines on monitor in Windows 10/8/7? This post has shown you how to fix the problem. Just try these methods above to troubleshoot it if you are bothered by computer screen lines.

Word can automatically count the lines in a document and display the appropriate number beside each line of text. This is useful when you need to refer to specific lines in a document, such as a script or a legal contract.

I’ve owned a Toshiba M55-S3294 since October, 2005. I’ve seen your first example on my own laptop only once and it went away when I rebooted the machine and has never appeared again but it’s nice to know replacing the LCD isn’t to hard after reading around your site.

I do have another question about the same laptop. Can the lid over (mine is copper) be removed without taking the LCD out? I’ve read you can change the color, so before I go looking for one on eBay, I wanted to know what I was getting myself into.

I have a Satellite P30 and today a vertical strip approximately 1 inch wide down the left hand side of the screen turned white. I can move my mouse cursor over to where the “Start” button is in Windows, and activate the “Start” button, however, I can’t see the button or the mouse cursor. Any ideas what might be the cause and solution to this problem?

Most likely it’s the LCD screen problem. Just in case try to connect an external monitor and check out the video output. If you see the same vertical strip (very unlikely), then it’s onboard video problem – the motherboard problem. If the external video is fine, then I would suspect the LCD screen itself. Try to twist the screen, apply some tension to it. Does the vertical strip changes location, color or width?

my screen is dim, it flickers but no lines like in these exampes. the external monitor works fine. i have a m35x-s111 sometimes i can make out whats on the screen but most of the time its to dim. please help. great site

i have a prob that i don’t see discussed yet…..i’m in dire need of help….my toshiba a70 has a prob..it only displays about 11 inches of video on the screen…the right side 3 or 4 inches are black…it works well on an external monitor…no luck updating drivers… also it does the same thing in safe mode…..please gimme a holla on where to go and what to do.i heard you were the best out there

Turn on the laptop and go into BIOS setup. I believe you’ll have to hit ESC key on start up for this laptop to enter the setup. Do you see the same lines when you are in BIOS? If not, then I would say that’s software issue and re-imaging the drive will fix the problem. If the lines are still there, even when you are in BIOS, then it would be a hardware related problem, most likely a bad screen.

I have a Pro-Star 8790. Everything was running fine until a couple months ago. My video distorts at random and forces me to restart my laptop. But I’ve noticed that it only does it when the laptop is plugged in. I listened and heard a quiet clicking noise coming from my power supply (like small sparks) and decided that that was the problem. Now, I’ve bought a brand new AC adapter and it didn’t solve the problem at all. My screen still distorts forcing a restart. I know it’s not a driver problem either. My video card is integrated into my system. I now think it is a video card problem. Does this mean my video card/laptop is fried?

Have you tried to connect an external monitor to the laptop? What about external video, is it bad too? If both screens – internal LCD and external monitor display the same distorted video, then I would suspect the system board. Let me know how it goes with the external video output.

hi, there i have slight problem with my lcd unfortunately the top 8 cm of my screen are gray and do not work, i assume it is completely broken a therefore wish to replace it however my warranty has run out. so i plan on doing it myself, i have two questions relating to this and would really appreciate if you could help me answer them. First of all the laptop in question is a fujitsu-siemens Amilo m7400 and i was wondering if i could replace my lcd with my friends Amilo m7405, in terms of resolution and size they seem identical, however i would appreciate if you could tell me whether or not i am barking up the right tree, my thoughts were that since they were the same model basically that fujitsu would probably have used the same lcd. secondly could you possibly tell me were i could get hold of some sort of manual or instructions. thanks.

It has gotten progressively worse over time. If you apply some pressure to the screen frame, the display will return to normal and the small vertical line will go away. I would assume that this is a loose connection? I intend to remove the frame and re-seat the inverter, LCD cable and do some cleaning. Does this seem like a failing LCD screen? The computer is slightly over a year old.

I would try removing the LCD and putting it back and hope for a miracle. Last month it helped me to “fix” a bad LCD on IBM ThinkPad. The screen was bad, it had some horizontal lines on it. Reseating cables and replacing the video cable didn’t help. But, after I removed the screen and put it back I got a perfect video. I think that when I put all screws on sides back in place, they stretched the screen somehow and made it work fine. I’ve never seen the customer again. I don’t know if it’s going to help you, but I think it worth trying.

I forgot to mention that the screen goes dim every couple of minutes as well. If you give the back of the screen a light tap, it will return to normal. Can you give me any ideas of where to look for a replacement LCD if that is the problem?

With backlight it could be a loose connection problem, try reseating cables on the inverter board. To find a replacement screen, you’ll have to search by the part number. You can find the part number on the back of the LCD screen and it looks like: A000002050 (you might have different part number). Try searching through Google or on eBay. LCD screens are very expensive and very often it doesn’t make any sense to replace the screen, it’s better to buy a new laptop.

If you cannot find the part number for the LCD, give me more info about your laptop: model number and part number from the bottom and I’ll look up a part number for you.

just an update, but disassembling the LCD and re-seating the connections as well as the inverter seems to have fixed the problem. Thanks for your advice.

hello sir, i have a compaq armada M700 laptop…since yesterday i am getting a horizontal line exactly at the middle of the screen. every thing is working absolutely fine. the line is about half a milimitre thick. what should i do…take it to a techician or can i repair it myself

I woke up this morning, turn on my Dell Inspiron 6000 and theres a vertical line. Reboot, Reboot in safe mode and line still there and everything runs fine. After reading the great info on this site it seems a my screen has gone bad. Below is a link to my screen while XP is booting. I need a new screen right? Just wanted to get some feedback before I go spending on one. Thanks in advance.

It looks like a bad screen. From my experience, this kind of failure (thin vertical line across the screen) is not related to a failed video cable, bad connection or bad video card.

I have blue and purple vertical lines along the bottom 40% of my laptop screen and absolutely no image (entirely lines). The top 60% of the screen works great! I tried contacting Gateway but they won’t even answer me as to what it could possibly be without me paying them $3 per minute for cusomter support! Argh! Any advice on why only part of the screen is on the fritz? Thank you.

Start laptop troubleshooting with connecting an external monitor. That’s the first thing to do when you have a bad image on the LCD screen. If the same blue and purple vertical lines occur on the external monitor, then it’s the motherboard (video card) problem. If the external video is fine, then I would say that you might have a bad LCD screen.

Hi I have a Satellite p35-s605,which has developed a red horizontal line on the display,when connected to an ext monitor there is no line,guess Lcd problem also have reinstaled the os and drivers,

I have a gateway m500 that fell off a desk and crack the LCD. I couldnt use the external monitor so we sent it in for warranty to use the external display. I bought another lcd, put it in, replaced the cables,and now I get color with vertical lines but no picture. Now that I have replaced all of this, my external monitor no longer works. Do you have any ideas on what needs to be replaced next? please let me know. Thank you

I have a Gateway 400SD4. When you first turn on the laptop you can see data on the screen but just for s second then the screen goes white, quite brite too! You cannot see any data on the screen. The external monitor looks great. Any ideas? Thanks!

Have you tested if the laptop works fine with an external screen before you replaced the internal LCD? Disconnect the internal video cable from the motherboard and test it again with an external screen. If you still get the same lines on the external video, even when internal LCD is disconnected, then I would say that’s a bad motherboard (video card if it’s a separate module).

If the external monitor works fine after you disconnect the video cable from the motherboard, connect the cable back and test it again. It might be just a loose connection. If you still have the same bad video, then you might have a bad screen.

It’s hard to guess. First of all, I would check if the video cable on the back of the LCD screen makes a good connection with the screen. I’m not sure if it’s going to help you, but I know that on some Toshiba laptop the same white screen appears when the video cable is not seated properly.

If reseating cables doesn’t help, then it could be either the motherboard or the screen problem. I would say most likely it’s a bad screen but I’m not 100% confident.

Thanks for your response. I took the laptop apart and checked every wire in the cable going to the display and could not find any problems with the cable. Even found there is a fuse on the circuit board but that was OK. I put the unit back together and now it’s working! I think you were right, probably just a loose cable as the connection to the LCD itself does not feel that secure.

I was a laptop technician in a company that only uses Dell, IBM and Compaq. I just recently started my own business in a Flea Market and have come across Toshiba laptops that recently needed screen replacements due to accidents and dc-inline jacks that need to be replaced. Your website is a life saver for a tech that is new to the Toshiba brand. I will continue to contribute what I can as I use your website.

I have a dell 9400 with a wuxga true life display. Recently the video card was changed and then the lcd had a blueish tint and no blacks whatsoever. When plugged into a crt all the colors are fine and the video card works good as well. Dell is sending someone out to replace the motherboard and video card, i was wondering if you have ever run into this problem and the cause…Before the lcd was replaced it was wavy and the windows logo during start up was shadowing.. along with distortions to the color. The wavy ness is pretty much gone but no blacks color distortion and a blue tint remaiins… any ideas? why would they change the motherboard?

I haven’t seen a laptop screen with bluish tint yet, but I’ve seen a reddish tint many times. In most cases, if the reddish tint appears on both screens – internal LCD and external monitor, it’s the system board/video card problem. If the reddish screen appears only on the internal LCD screen but not on the external monitor, then I would suspect the screen itself first. I guess the same would apply to a bluish tint.

I think they are replacing the motherboard just as a precaution. Please, let us know what parts Dell technician will replace and if it fixes the problem.

you problem could possibly be the vga cable, or connection of the vga cable. when you check this problem please make sure that your laptop in completely turn off the battery is removed, whit screen is signe of fauly cable or disconnected cable, that is the case if the laptop works on external monitor, else check you video memory. this sort of problem could also couse by dry joint, at mother board chip, or cable connection area.

Thank you for providing all of the laptop lcd tips. I have 2 laptops with pretty much the same issue with a very dim screen or no backlight. Both laptops are fine on external monitor.

The first laptop is an Acer Aspire 3000 that is dim throughout the boot process but a Toshiba M45 has a good screen for about 10 seconds, flickers and then goes dim. I am suspecting both laptops to have a bad FL inverter that needs replacing. Do you have any other suggestions to try? Thanks.

I’ve posted some laptop video troubleshooting tips in this post. Most likely it’s just a failed FL inverter board on both laptops. If Acer Aspire 3000 has a regular lid close switch (not a magnetic one), make sure it’s not stuck and moves freely.

I have reseated cable hardness from lcd to mothe board so many time. My question is…is it the inverter i have ordered and replaced is bad. I think the invert board is to convert small dc voltage into high RMS voltage to ignite the backligh and control

I recently purchased a toshiba satellite p35-s609 from ebay, my problem is similar to bernie’s in which when booting up there will be a couple red lines on the left side of the screen, while installing windows xp I noticed that there is a reddish hue and diminished color (the white sunburst gradient cirles on the background of the windows turn into reddish circles), this problem is not duplicated on an external monitor. I found that if I tilt the laptop a little will reset the color and brightness to its normal display and stay like that as long as it is kept in that position (which is a little awkward at times). Could this hopefully just be a loose connection from the LCD to the motherboard? I have yet to open it up and wondering what my current options are.

I’ve never seen that FL inverter causes such a problem. You a right, the inverter convert voltage for the backlight bulb, but from my knowledge it cannot affect colors on the screen. I guess you might have a failed video cable, but most likely it’s a bad screen.

BTW, look inside the video connector on the motherboard and video connector on the back of the LCD screen. Check if there are any bent pins. Last week I had to repair Toshiba Satellite P30 with a backlight problem. After 15 minutes of testing I discovered that couple pins inside the connector on the motherboard were bent and the video cable didn’t seat properly. The problem was fixed after I carefully straightened the pins.

In the top navigation bar there is a tab “Laptop Parts”. In there I listed 2-3 companies who sell LCD screens for Toshiba. We worked with Spare Parts Warehouse and AG Parts (used to be ID parts) and don’t have any complaints. Man, screens are expensive.

What does work though is if I leave the lcd screen connected but remove it from the case (so it’s not touching the laptop) the lines go away. Is this a grounding issue. It seems like I am close to fixing it but can’t figure it out…

Hi! I just got a new laptop: the HP Pavilion DV8333EA and I’m already facing problems! It’s not a major issue but there seems to be a strong pink tint between text on my lcd screen; particularly between vertical characters such as ‘t’, ‘l’ and ‘i’. It’s quite distracting and I didn’t expect such from a brand new laptop. How can I resolve this?

Is your laptop still under warranty? It could be a major issue with the LCD screen or with the video card. A new computer shouldn’t have any pink tint between characters.

Connect an external monitor and turn on the laptop. If you can see the same pink tint on the external monitor, then it could be related to the motherboard (video card). If the external monitor displays characters fine and the problem appears only on the internal LCD screen, then it could be the screen problem.

Test the laptop with an external monitor attached. If the external video as bad as the internal, then it could be the motherboard (or video card) failure. If the external video is fine, and you have a problem only with the internal LCD, then I would check if the video cable got loose. Probably you’ll have to reseat both connections – one on the motherboard and one on the back of the LCD screen. If reseating the cable will not help, probably it’s a hardware issue.

How about this one. Toshiba A105-S2716 Laptop and everything is working fine. Then the screen goes grey with a few white lines running horizontal across it. The external monitor is working fine, and if I cycle through the Fn-F5 key, the LCD starts working again for awhile. Also, if I reboot it starts to work again for awhile. The time it takes to go to the grey screen is intermittent though. It could be 2 minutes or 20. I’m not sure which component may be bad. Thanks for a great site.

Yeah that’s a weird one. I’ve seen a few Satellite 105 laptops with a problem like that. It works fine for 10-15 minutes and then the screen goes gray with a few horizontal white lines.

When I got a Satellite A105 laptop with this problem for the first time it took me just 10 minutes to troubleshoot it. I connected an external monitor and set the video output on both screens. After 10-15 minutes the internal LCD screen failed but the external video was fine. I just ordered a new screen and video cable (as a precaution) because it looked like 100% LCD issue. BUT replacing the screen with video cable DIDN’T fix the problem. The same gray screen appeared after about 10 minutes. Reflashing the BIOS didn’t help either. After that I ordered a new system board and the problem was fixed.

I don’t want you to encourage buying a new system board right away, because in your case it could be just a bad screen. That’s would be nice if you can find a spare LCD screen and test it for a while. But from my experience this kind of failure on Satellite A105 laptops is caused by faulty system board. As I said before, that’s a wired one.

Hi, i have a prob similar to the 1st one that has been discussed. There r lot of horizontal lines that appear on the lcd and the whole display looks inverted and out of focus. Is the problem very common with M55s?

Hi there. I’ve recently inherited an Inspiron 8000 which works perfectly apart from one thing. When the display resolution is set to the lowest setting the windows desktop is off centre, to the bottom right of the screen.When the resolution is set to the highest setting the right and bottom 3 inches of the desktop are off the screen! I have updated bios,drivers,reformatted the hard drive and re-installed windows. Any help would be much appreciated.

I have installed the latest nvidia driver for the graphics card to no avail. The screen is offset in any resolution. I should mention that the bios and bios splash screen are also off centre. When the laptop is connected to an external monitor everything is fine. I have checked that the graphics card and connectors are all seated correctly.Any other thoughts would be gratefully received.

So it’s not software failure at all, because the screen is off center even before the operating system starts loading. You’ve already updated the BIOS, so it’s not the BIOS issue.

I afraid that it could be either the video card failure or the LCD failure. I cannot narrow it down without test LCD. I don’t think that the video cable can cause such problem.

My notebook’s screen has blue background colour even then it should be black, for example at startup or in DOS command prompt window, so the colours of the screen are distorted. I can send photo to email. External monitor working absolutely OK, even then I replaced the LCD panel the problem persisted. What do you recommend to check?

So you’ve replaced the LCD screen and still have the same problem? Man, that’s was an expensive one, but at least you know that’s not the screen problem.

Before you buy any parts, I would try reflashing/upgrading the laptop BIOS. It’s not likely that the BIOS is corrupted, but it’s possible. I’ve seen some few strange problems with video that was fixed by reflashing the BIOS.

If you experience a problem with the video output on the laptop LCD screen but not on the external monitor, then in most cases it would indicate a display related issue. If onboard video card is bad, the same video problem usually appears on both screens, internal and external. It’s not a rule, but from my experience it’s correct most of the time. I think that you have a problem with the LCD screen but after you mentioned this:

Hey thanks for your reply. It’s got me stumped. I changed the inverter and cable and no difference. The diagnostics clearly say that LCD, inverter, cable are all fine. Problem with adaptor…go figure. The most annoying thing is that it was only 1 year and 9 months old when it had this problem. The laptop is absolutely mint condition, I have used it as a ‘desktop’, not even taken it out more than 5 ocassions! If I need a laptop I’m gonna use my girlfriend’s Intel Macbook. Gonna build my own desktop, that way I can fix it easily.

I have an old 5105-S901 which, within a few minutes of running, shows an increasing amount of random pixel trash on the screen – similar to some of your screenshots (both on LCD and external monitor; shows as corrupted ASCII characters during boot-up). In 640×480 (safe mode) it works relatively stable for a while, but it crashes with ‘unknown hardware failure’ within minutes if it’s running in higher resolutions. After spending countless hours of testing, cleaning, replacing memory and experimenting, I found out that it’s a temperature issue with the video card. The Nvidia chip is getting extremely hot (burnt my finger twice) and if I spray liquid ice on it, the pixel trash immediately goes away. The video card has no active cooling, so I guess it became defective from permanent overheating over the years. I’m not quite sure what to do now – I can’t leave the laptop open all the time and spray stuff on it every 5 minutes. A new video card is ridiculously expensive ($350 – Walmart has a complete laptop for that price) and I wonder if and for how long it would solve the problem. I already force the CPU fan to run permantently at 100%, but that doesn’t help the video card. Is there a way to improve the video card’s cooling in my laptop model ? Have others experienced similar problems?

I have a used ThinkPad T40. I’ve noticed that if direct sunlight hits the back of the screen (the cover), the screen gets multi-colored lines all over. The couple of times that my roommate left the computer in the sun, the lines would disappear after we’d let it cool down. I can only blame myself for this, but the other day I left the laptop near the window, and the sun attacked it once again. Now it’s been two days and many reboots, and I only get picture (on the top half of the screen) when I first turn the laptop on, then it goes to colored or grey lines. I haven’t found any info on the net about screens overheating in sunlight – but is this possible? Is something permanently fried, or can it be tweaked?

I’ve never ever seen or heard about laptop screen overheating in sunlight. Probably I should sacrifice one of my laptops and leave it in the sun to see if I can reproduce the problem.
