Laptop screen flickering & horizontal lines in Inspiron 15r SE 7520

Q: Laptop screen flickering & horizontal lines in Inspiron 15r SE 7520

I've a Dell inspiron 15r se laptop which is 1.1years old( model - 7520). It was working fine until last couple of days. Last week it started giving a horizontal white dot line on the very top of screen( like this ............. in white) for the entire width of the screen. From yesterday or so a similar line started appearing at the bottom too. Both of these line will come and go every 2 or 3 sec. And screen will jump a bit (like say 5 pixel or so roughly) and it will also shake sometimes which makes letters difficult to read.
The problem exists everywhere, even in boot screen. In short when I press power button and screen start displaying something problem also starts.
Today I connected an external lcd monitor via vga cable and it works fine. No line and no flickering. So I guess GPU is ok?? What could be the problem?? Could it be just loose contact or something in laptop screen cable?
Another question: I had warranty including accidental damage protection and stuff for a year. But since I'm outside this period now, what should I do?
And since I'm outside the warranty period anyway is it okay if I open my laptop and try something?
Please help!!

I got back from vacation and plugged my laptop in to work on pictures when some vertical lines and a bunch of horizontal squiggly lines popped up.  I can't figure out what has caused them.
I've run CCleaner & Super Anti-virus to ensure it's not malware.
I've run the Dell PC Diagnostic full test (which said their was an error and could not provide the results).  So I ran individual tests on video card, video stress test, monitor, and they all came fine.  
I am now going to reboot in safe mode and see if I can run off a motherboard video system & see if it's the video card.
I don't really have any idea what I'm doing so any help would be great!

Hello,I just bought a new Pavilion dv6 (LW272UA#ABC) ten days ago and I've noticed that after the screen turns off due to inactivity, or because I close the lid to let the notebook sleep, two to three horizontal white lines flicker on and off  at the top of the screen every few seconds until I restart the computer. Should I be worried ? Should I ask for a replacement from the store tomorrow or should I wait to see if the problem becomes worse or until HP/NVIDIA release a driver update ?

A:Horizontal flickering lines on dv6 screen

I have had this same problem, I bought a pavilion dv6-6140us on Aug 4, 2011, it had the horizontal line issue. I exchanged that one on aug 17, 2011 to my local best buy for the same exact laptop. yesterday this new system starting doing the same thing. glad to know im not the only one, any help would be great. I dont believe the issue is with the graphics card because I have a raedon and constantin has a nvidia. however I have noticed that the problem is more severe when I have something in fullscreen. so maybe it is in the programming, but I feel like its a hardware issue. Thanks in advance ?

Since the issue would be intermittent , next time that it would happen to best take a picture of the image and likewise try to connect it with an external monitor to check if the same issue would appear.

So recently my computer has been experiencing some issues. Black horizontal lines have been showing up all over the screen. At first they were intermittent but now they seems to be happening more often and it's getting worse. Could this be an issue with the graphics card or the graphics driver? The lines do not show up in a screenshot if that says anything. I have a Lenovo yoga 11s with windows 10 and have only had it for 2 years. I would really like not to have to replace my computer because of this.

My system:
DELL XPS 15 Laptop 9530
Windows 8.1
About three weeks after I purchased this machine, flickering horizontal lines began appearing across the screen.  They are transparent, a little less than 1cm in height and traverse the whole width of the screen.  Each line is separated from the next by about a quarter of the screen height.  There are three of them currently and they always appear at the same height on the screen.  They are barely noticeable on a white background but can be prominent and annoying on dark backgrounds or photos etc. 
Have run all the diagnostic protocols on the DELL website – everything working perfectly. 
Not sure whether this is a hardware or software problem.
Any help appreciated.

Hi ,
Thank you for writing to the Dell Community Forum .
In this case do confirm if you have performed these steps and advise ,
*Have you checked the system's performance in safe mode ,because safe mode uses very minimal drivers and graphics if the issue is seen in safe mode then its a hardware issue.
*What happens when an external monitor is connected to the system ?If the lines are not seen on the external screen then the system board works fine  .
*Have you tried to initiate LCD BIST ( by restarting the system and pressing the D-Key on startup ,solid colours should be visible clearly if the test passes )
*May I know how were the diagnostics initiated on the system.
Hoping to hear from you soon with the service tag of the system (send it via private message only ) so that I can check the specifications of the system .
Kindest Regards ,

Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.(If the battery is internal, please just skip the remove/replace battery steps.)1. Turn the unit off2. Remove the battery and the Mains adapter3. Press and hold the front power button for 30 seconds4. Replace the battery and the Mains adapter5. Turn the unit on as normal

about five days ago my mom's laptop (acer aspire 7520) suddenly displayed a horizontally split screen, as follow up it also crashed and then failed to boot etc. causing me to spend the last two days getting it back to work.

the split screen is seperated by a thin white line across the monitor and both halfs display the same, including mouse movements. the whole desktop is visible on both halfs each and functions properly except being a bit blurry. also, the screens are both misplaced on the monitor, meaning they're left aligned.

the split screen appears at random, mostly already on the first screen after turning the laptop on, when MS-DOS is loading(?). while the laptop had no OS (I mean software..) on it the split screen appeared more frequently and a friend of mine suspects a hardware failure. oddly enough, the split screen did not occur for a while after the reinstallment of win7 x32 home premium.

I'm really puzzled about what is causing this problem.

about the laptop:

acer aspire 7520 (about 4 years old)
AMD Turion 64 X2 Mobile TL-60 (3.2 GHz)
3 GB DDR2 RAM
" Standard VGA-Grafikkarte" (Ati X1250 ? )
->NVIDIA GeForce 8400M G




I'm new to this so please bear with my lack of knowledge/ comprehension. :blush:

any help appreciated!

Hi all,
The screen of my Inspiron 3520 randomly becomes completely covered in white fuzzy lines; the entire screen.
There is no particular pattern for when this happens. It sometimes happens as soon as I log in and begin typing and/or clicking on the mouse pad, and on other occasions I can use the laptop for a good hour or two before it happens. Today, for example, I used the laptop for 5 minutes and it happened 4 times, with each occasion lasting about 20-30 seconds in duration. However, yesterday I used the laptop for over an hour and it didn't happen at all.
I imagine this is a hardware problem relating to a wire connecting the screen as it only happens when I'm actually using the laptop to type or surf the web etc (I can watch a film on the laptop for a straight 2 hours and it won't happen once, so long as I don't touch the machine). So I'm thinking that possibly the mild vibrations caused by me pressing the keys and/or mouse pad are causing a wire to disconnect or become lose. It doesn't matter if the laptop is 'hot' or 'cold: it's indiscriminate.
I have ran all the applicable tests on SupportAssist and no issue is found. I've also updated all drivers. About 6 months ago I upgraded from Windows 8.1 to 10 and the problem stopped for a short while, so I was hopeful it had been a software glitch. However it soon started again and now it's happening so frequently the laptop is basically useless, other than for watching films/c... Read more

If that's the cause, then the image should be ok on an external screen - that would be the first thing to check.  
If it's not, the problem is with the mainboard.

For quite some time now (Well over a couple of years) I've noticed small flickering black horizontal lines on my monitor usually coming out of the bottom-right hand side of the screen (Sometimes top-right). But they're not just lines. It's more like a graphical artifact. The line actually looks like dots, and it flickers until it starts getting shorter and vanishes (The movement of the line kind of reminds me of Snake). It doesn't always happen but often does happen on YouTube, seemingly exacerbated by scrolling.

I tried taking a screenshot of it, but it doesn't show up on screenshots.

The monitor is a Hanns-G LCD (28"). I wouldn't be overly surprised if the monitor is faulty as I've not been able to wake the monitor up from sleeping for years (I have to physically turn it off and then on).
 

A:Flickering Horizontal Lines

If the problem doesn't show up in a screen shot it is a problem with either the monitor or the video cable usually. Also having to manually wake the monitor up from sleep points to a monitor problem.

When I'm running any game and the camera starts to move decently fast, there are horizontal flickering lines (usually 2 or 3 visible, always in the upper half of the screen). Then when the movement stops, the lines disappear. I've tried troubleshooting and messing with the refresh rate, for I thought initially that the problem had to do with that, but to no avail.

I recently purchased a Dell Computer. Periodically and randomly, sepia-colored flickering horizontal lines appear on the screen. It looks like static for a few seconds then disappears. Sometimes it covers almost 100% of the screen. I called the Dell Cust. Service line. They confidently suggested it was because my cell phone was near the monitor. I moved the phone, but the problem continues. I have not called them back because they didn't seem very willing to suggest other potential causes/fixes.

I found info. on the Net suggesting to adjust the refresh rate -- which I did. I raised it from 75 to 85. It seemed to help for a little while but may have been just coincidental. The problem continues.

Any experiences, ideas or potential solutions would be very appreciated. Thank you.
 

A:Monitor Flickering Horizontal Lines

You give no details of the monitor type, which makes it difficult to help, but we could assume a CRT type monitor from the refresh rates I suppose..

Intermittent problems such as this are certainly not going to be related to the reresh rates.

It really does sound like cellular phone type interference, a cellphone "phones home" every few minutes (random) to let the network know it is alive. This interference can affect a CRT monitor from several metres away.

Also any mains type appliance will affect a CRT monitor if it is within range of the magnetic field produced, as will any radio frequency device (but that range can be very large).

I am completely baffled by this one. My AIO 700-27ISH (UHD resolution) has recently started showing flickering horizontal lines on the display. This has happended about a week after upgrading to Windows 10 2017 Fall Creators Update. In troubleshooting the problem, i first checked the Windows 10 Device Manager, and all was listed as working properly. Then I scanned for malware and found none. Then I updated all of my video card drivers (Intel HD 530 and NVIDIA 950A) and still no joy. I also did a Lenovo Solution Center hardware scan that came back with no issues. Then I unplugged the unit and then plugged it back in after 5 mins, and still saw horizontal flickering lines. Finally, I hooked up a UHD TV to the computer via the HDMI-Out port, and the display on the TV had no flickering or lines, while the computer display continued to show lines. This lead me to conclude that perhaps the display itself was faulty. However, I just did some online diagnostics on the Lenovo Support site, and there were no faults identified for the display. Since my computer is out of warranty, I'd like to do what I can before spending big bucks on chasing down and rectifying the problem. However, I'm out of thoughts on how to proceed next. The only driver I have not updated is the driver for the display itself. Windows says I have the most current driver and I can't find any others on the Lenovo Support site. Any suggestions? By the way, I've had the Lenovo Ideacentre Scalar Fonts Imp... Read more

I have a Toshiba Equium P200D-139 laptop and the screen stopped working. It lights up but the display consists of vertical lines, which slowly fade into a black screen.
I tried it on an external monitor and it worked fine, (so presumably cannot be a faulty graphics card/motherboard). So, I thought it was likely to be either be the inverter or the screen itself.
After trying a new inverter with no success, I bought another second hand screen. However, the new screen has the exact same problem with the ‘horizonal lines’ display. Just occassionally, I catch a glimpse of a partial Vista screensaver for a split second but then its back to black. I’m not a technophobe, so any info would be very much appreciated.

Hi all,

I just got a brand new Asus VH236H monitor from Newegg. Pulled it out of the box, set it up on my desk, plugged it in, connected it to my laptop (Acer Aspire 6920), and all was good. That was about 6 hours ago.

Now, I'm seeing horizontal flickering lines all over the screen. Some are thin lines, others are thick bands. They're constantly moving up and down the whole display. Did some research, and seems like when this happens, it happens on all inputs. But the funny thing is, for me the flickering lines are only visible when in VGA mode. When I switch to HDMI (my Playstation 3), all is well. No lines anywhere in sight. Unfortunately, I don't have any DVI devices to also check that input.

I've checked all the resolution/refresh rate options given to me, and they're set to the recommended Asus values (1920x1080, 60Hz).

Can anyone tell me if this is a defect with the monitor, or if I need to find some advanced setting somewhere, and change that.

Thanks

First thing, does this occur as soon as you turn the machine on or only when you log into Windows (assuming your running windows)?

Check all the external cabling first, make sure they are all securely connected etc. Also check internal cabling and remove and reseat the graphics card (if it is an add on card) and re-test.

I purchased a new Z27s monitor on Amazon 9 months ago.  One week ago, after a scan with Avast, the lower half of the screen started flickering and I have horozontal black lines across the entire display.  It clears up for a few minutes once in a while but overall, it's a banded, flickering mess.  I've used Avast since I purchased the monitor so I don't think it would suddenly cause problems, but I could be wrong. I've tried pluging it directly in the wall instead of a strip, using an outlet that's not on the same breaker, removing all phones, turning off nearby networking/wifi devices, hooking it up to a different computer to make sure it wasn't my GPU, using a different hdmi cable and using different hdmi ports.  Nothing helps.  Does anyone know what the problem might be?Also, when I checked out the HP warranty,  I found the product number is not associated with the serial number.  I'm wondering if that means I have counterfeit equipment.

My roommate turned his laptop on the other day and half the screen is messed up. It is horizontal lines in a rainbow of colors. You can still kind of see what should be there but it is pixelated and difficult. When i took a print screen image to post on here, the picture that it took was normal, without the ilnes. Can anyone help?
 

A:Half laptop screen has horizontal rainbow lines

That's pretty much common in laptops/notebooks, it's a hardware issue. Try to connect the laptop to an external monitor; if everything is displayed correctly on the external screen, then your room-mate's laptop has a faulty LCD screen and/or inventer.

Hello all.

I have a Dell Latitude D600 and at random times the display will flicker with horizontal lines. I can sometimes agitate it by gently twisting the LCD and it will flicker. I've done some research before and thought the problem would be the flex video cable, which I ordered and installed, but it still flickers. The LCD looks cosmetically perfect, as well as the inverter. The display backlight isn't flickering, rather there are white lines that flicker randomly, so I don't think it's the inverter.

I hooked it up via VGA to an external machine and only the laptop suffered the flicking so I believe that the graphics card is fine.

Here's a video on what I'm talking about.

Bump. I checked the flex cable connections to both the LCD and motherboard, and they're both fine.

The problem is a consistent one.  I get a teal colored shading (which is stable) over some parts of the screen and flickering narrow white horizontal lines on some images.  It doesn't matter what the medium is (video, image, desktop). The monitor tests fine.  The problem started without warning and I made no changes to the computer before it started. The only occurrences which might be responsible were a series of power outages we had while the computer was running.  I never really noticed if the problem started right after that or not. Since then I have replaced the CPU, the video card and the HDMI cable.  I also flashed the BIOS in case that got corrupted.  None of these fixed the problem. It's not overheating...CPU and GPU both running in the 40's Celsius.  The RAM passes all memory tests.  Is it possibly the power supply?  I've had them go out before but this wasn't what happened before they did.  Does anyone have an idea?

You did not say what OS or Dell Model.  Video artifacts like that are a sign of GPU overheating.

Hi all,

Found this site and was hoping for some help. A couple weeks ago, I turned on my ASUS G74SX-XR1 and the screen never came on. I took out the battery and discharged the static electricity and my computer started up fine. Well yesterday, after coming back from a vacation where I took my laptop with me and used it all weekend, my laptop screen wouldn't come on again. I tried the same method as before and it still didn't work. Troubleshooting it, I found that the backlight wasn't coming on. Graphics card OK. I saw with a flashlight that the computer was running, but it was running Startup Repair. This worried me. I let the computer set for a day and today it starts up fine, backlight and all. But, now my laptop connects to the router, but with no internet access both wireless and wired connections neither at home or at school. Also, some basic startup programs that I've never had a problem with, are now crashing on startup. Can these two problems be related? Or is it an inverter going out and corruption of files?

Hello,
I open and close the lid a lot and since a few minutes my laptop have a pink vertical lines on the whole display and they appear everywhere. On the start sceen, bios, windows etc. Also when I change the position of the lid most of the lines dissapear for a while. I have run the lcd bist test and the lines are not shown there. Does this means that the problem is in the lcd cable? Could it be the lcd display itself or the video? I am also using an external monitor and it working fine there.
Thank you.

It could very well be the wiring harness -- andd that would be the first thing to replace.  If you need a part reference, please supply the complete system model information (i.e., Inspiron 5521, etc. - NOT just Inspiron 15).

I just got a new HP laptop in October and a couple days ago as I'm online reading the screen randomly blacks out with a bunch of white and grayish horizontal lines probably like 6 rows of them all over the screen and itd flicker so the lines move randomly. Whenever it does that I cant see anything else but the black screen and lines. Its happened a few times since and happening more frequently. This is a new laptop that Ive barely used so I really hope I can get it fixed. I have McAfee protection and I've checked a few times and it says everythings good theres no virus.

I have a Dell Inspiron 15r 7520. Windows 10 home. Core i7 7th gen. I bought it from a guy on eBay a year ago. The screen will randomly start flickering/glitching with black lines(i can still see the stuff i was doing before its just distorted and moving) it also makes a errr sound that's ear grating. I have to shut down it with the power button because it doesn't respond to anything. I reboot and it will most of the time be just fine and not glitch for up to 3 days at the absolute most, but it always comes back. Sometimes it even wont boot up and will beep 4 times then pause and repeat(pretty annoying) I thought it was the graphics card (i have two the intel 4000 that's built in to the motherboard and a AMD Radeon graphics card) I did a dell diagnostic just on the graphics cards and it says they are fine. There were driver updates so i updated and i still have the problem. So I did the full diagnostic that takes 40 mins. It says that the hard drive and the battery have some issue. The test that the hard drive failed are Linear Read Test and SMART Short Self Test. The battery has always had an issue (really short life) that wasn't a surprise to me. I looked up hard drive failure and it just doesn't match with my issues. I also hear a click noise that happens once a day and dust blows out the side where the fan is. I thought it might be overheating on top of all this so i tried to open it to clean it out, but two of the screws are stuck so i cant even s... Read more

Hi Guys,

One of my first posts on this forum, as its my first DELL machine.
The workstation is:

DELL M3800 
CPU i7-4712HQ
GPU NVIDIA Quadro K1100M
W10 Pro

Over the last few months, the screen has developed two horizontal lines (Splitting the display into 3 segments) that appear to flicker when showing certain shades of colour. The flicker is completely invisible under white or black backgrounds, but becomes extremely noticeable under different shades of grey, and other darker colours. The lines appear to start approx .5 cm from the left edge with a sharp contrast, and fade away towards the right edge.
The flicker appears to be getting progressively worse over the past couple of weeks, but does go away sometimes altogether.

I have reinstalled my video and chipset drivers and am running out of ideas. 
Tried a HDMI connection to a TV, and the lines are not present, which seems to point towards the display being faulty? 

Any suggestions on what could be causing this would be greatly appreciated!

If you are also using the same HDMI to connect to your regular monitor that you connected to the TV, then, yes, the display is probably faulty.

Hi
My Laptop is 13 months old Dell I7 5558, i was facing this screen flicker issue previously ,where i got my Laptop Screen replaced by you ,but now I'm facing the same issue . 
Previously before replacing i used to have just few flicker,now flicker rate got increased even more & Screen Goes black which is really annoying.
Even at the logo Screen I 'm seeing Green & pink lines
Sometimes nothing appears on the screen just  flicker of Green & pink lines & black Screen After that.Where i should  to remove my battery  & place it ,to turn on my laptop in this case.
Problem is not related to software, if that was the case flicker should not be at dell logo screen.
But FYI my Graphic Card Drivers are already up to date.
I Guess the problem is at the hinges or with the monitor or maybe related to mother board itself.
when my laptop screen is less than 90 degree i can see few flicker,when it 90 degrees or more than that ,continuous flicker & black screen later as like monitor looses power nothing .

Any Other Information Required let me know.

Hi, I have recently updated my laptop with Win10 x64 Pro and all was working fine, I have the latest drivers, no other conflicts in Device Manager. This started recently may be 4 days back, in the middle of work, suddenly horizontal or vertical lines appear, it keeps flickering, when I restart, this is from very start, some times, it goes away on its own and sometimes I have to hit laptop body randomly anywhere and screen comes back. There is no set pattern or trigger, jus random, I have attached the screen image here. Any Advice would be appreciated.  Random lines in display?

A:My Z570 laptop screen flickering with lines random...

it looks like your hard drive has gone bad. i have a Y70 touch. i have upgraded to windows 10 3 times in the past year and each time the hard drive has gone bad shortly afterwards. although my screen flickers were not nearly as bad as yours, they were very annoying until the hard drive completely died the first 2 times. this last time i knew what was happening and was able to catch the problem before the hard drive completely failed. i had windows 10 installed without all the extra lenovo and other manufacturer programs that i didn't need and weren't compatible with windows 10. i never tried rolling back the system but i was told it wouldn't have helped at the point when the hard drives had failed.

I wasn't able to read what it says before the computer restarted.
Little back story, the computer had started running loudly which escalated to making a noise that almost sounded like grinding(or a piece of cardboard stuck in the fan). Couldn't figure it out so I gave up, last time I used it was January, but between last August and then it was only sporadic usage. A few weeks ago I turned it on again and there has been no abnormal noises, and out of no where I get the BSOD, computer still seems to be running fine.
Going to bed now, but will be on tomorrow afternoon to run any scans or give and needed info.
Thanks in advanced!
