Preferred Solution: thin blue line on laptop screen

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hi Kerberg, Can you try the following troubleshooting steps to see if it's hardware/software issue: - Connect the notebook to an external monitor to see if the line appears on the external monitor. - Go into BIOS by tapping "F10" key during boot up and see if the line appears on your main display. If it doesn't occur in BIOS, the hardware is good. We will have to focus on video drivers- onboard and discrete card. If the line appears on the screen, please call 800-334-5144, say notebook and then zbook through the promot. Thank you, -Tenzin

I have an HP Pavilion N5425 laptop, 14.1" LCD TFT (Toshiba) that works fine but 1 complaint:

About 1/4 way across the screen (from left to right) there is a thin blue line running from top to bottom.

It started very faintly but grew continually worse and is now a "permanent" feature.

The screen and laptop are fine otherwise, and I've been able to check all internal connections and and component seating. But the this hasn't corrected the problem.

I can replace any peice, but what part is it? Screen? Cable? Video Card?

When I change resolutions, the line stays in the exact same place on the screen.

When I unplug the cable from back of the screen (leaving the invertor connected) the screen remains on and show a plain white field with no blue line.

Using the video-out from the laptop, the line does not appear when hooked to a TVs video-in. (I do not have a proper monitor to try this with.)

Gently moving the cable seems to have no effect. But there is a good length of it held still under the power-button pcb when the laptop is re-assembled enough to turn it on.

Anyone have any experience like this and have an idea as to which part to replace? Any more suggestions to try?

Random Blue Thin/Dotted Lines on My HP Laptop Screen

I was recently transfering files to my new laptop, and uninstalling programs on my old laptop when I suddenly got thin blue lines randomly on my old screen in dark or black areas (see images). It is not in the same location on the screen depending on what I am viewing.

I hooked an external monitor to my laptop and the image is perfect. Another odd thing is when I screen capture the bluelines and view the image file on another PC, they do not show.

Any ideas?

It could possibly be due to a faulty data cable and at worst the screen itself. Only solution would be to have it serviced by a Lenovo technician as it is most likely hardware related.

Had IBM Thinkpad 600E fixed under warranty for faulty screen (which had ceased to work) - problem turned out to be faulty motherboard, and motherboard was replaced.
Since getting the laptop back, there is a thin (about 4mm) vertical grey band down the entire screen which obliterates whatever is behind it. This line is about a cm in from the left hand side.
the band comes on from start up...ie through the black POST screen, and if operating in DOS - the same. The correct drivers and refresh rates, etc were already loaded. OS is Win98SE.
Wondering if it could be caused by something simple like a loose cable?
The reason I'm asking is that I'm in Sydney & have to send the laptop back to Melbourne to be fixed....if it is something that has happened in transit, there's no point sending it back to have the same thing happen again. Any ideas much appreciated.

A:Thin grey vertical band on laptop screen

That could be a physical flaw in the screen, but hopefully it's just a loosened connection in the wiring involved.

It probably did happen in transit, since the repair techs would have noticed and called you if they saw it.

You could have a local tech try to check the wiring first, but you'll probably have to send it to Melbourne again. If so, use a bigger box and ship it wrapped in something big and soft like a down-filled winter coat or quilt. You might also want to insure the parcel for the round trip if your postal system or courier company offers the option.

I hooked up an external monitor and i've confirmed that it is only on the laptop screen. Is this a common problem and is this something that Dell can resolve immediately with  replacement or is this something that will have to be sent in for repairs?

On my 3 year old laptop (HP dvEnvy7), a very thin line of black pixels has showed up. The first time it showed up was on the red background login screen, and I think tapping the monitor made it go away, but that might've been coincidence. I just noticed it again in the same place where the color of the screen is green. I was running an MBAM scan while that showed up and the line went away, again I don't know whether that was coincidence. I've read that this problem could be caused "by the traces going bad in the video cable going from the LCD the the main board" due to the laptop lid opening and closing. The lid is getting a bit loose. Is this the answer or could there be something more malicious, as my paranoia comes back to haunt me?

A:Thin black/dead vertical pixel line

If it's a single pixel width from edge to edge, it will almost certainly be a fault inside the LCD panel itself. Individual pixel drive signals are not carried on the LVDS cable connecting the panel to the mainboard, as that would require thousands of individual conductors. So a "hard fault" such as a complete black column or line is usually due to a bad connection in a heat bonded loom inside the panel, or an intermittent line or column driver IC which are also integrated into the bonded loom matrix inside the panel. Pressing or tapping the screen/frame can commonly make the symptom come and go in its early phases.
With that said, odd line-like faults can be a result of poor contact on the LVDS cable connector(s), and dismantling enough to gain access to this and cleaning the contacts with alcohol can solve it.

Hi there
If you are using an external TV type of monitor go into the menu of the Monitor -- usually via a remote controller etc. Somewhere in the Video / picture setups you should see an option like auto adjust picture / size or something like that -- then the image should fit the screen perfectly.

(Assuming of course that you have set the resolution (in the PC settings) of the monitor to one it can handle).

Hello...I have a thin blue line on the bottom of my lcd monitor. Not all the time though. It's only when the desk top, itunes and firefox / I.E. are up.. Maybe a millimeter wide. It's doen't go through the green "windows start" button when it is up or when the media player screen is on. So I don't think there is anything physically wrong with it. Is there any adjustment for this? It's not a big deal, it's just that knowing it's there is kinda aggravating.

Any help would be great

I have a solid thin red line running down my computer screen. It runs from the top edge to the bottom and is about 3 inches from the right edge.

It happened after I watched a film I streamed to my laptop. I connected my laptop to my Flat screen TV and used the TV as a secondary monitor. I noticed it after I finished watching the film.

The thing is my Laptop screen was still running while I watched the film on the TV. It was just on my Desktop background and at one point it was on the My Computer screen.

At first I though it could be image burn as the image on my laptop screen was still for a long period of time. However nothing on my Desktop background or the My Computer screen has a line that runs in unison to this line?

Any ideas what might have caused it and does any one know how to fix this?

I have restarted the computer many times and even opened up the computer to check the connectors on the screen but the line is still there.

Do I need to get a new screen or laptop? Please help

Hello all,

I have a question about my laptop which I was hoping someone can solve for me please?

I have a 3" (approx) black line running down the right hand side of my screen and a 1" (approx) black line running across the bottom of my screen and am not sure what this means!?

It's not dead pixels as I can see everything as normal (e.g the clock in the right hand corner) but it just looks like someone has comressed the screen into a smaller space and I cannot move the mouse into these black areas. It is also the same when I go to the BIOS. Not sure if this is a regular problem with Acers (mine's an Aspire 3690) but I cannot find anything on the internet about it? I restored the system to factory settings but was still the same.

Sometimes goes back to a full screen (however hasn't done it for a while though) and I have linked it to a monitor and the screen is full and does not have any black lines.

I am stuck on what to do so if someone could help I would really appreciate it. I have attached a picture to show what it currently looks like.

Okay so I just got my chinese-made laptop back from being fixed for the fourth time in a row (i live in north america...they are in australia... damn long time) and now i discover there is a 1-pixel wide vertical purple line on my 15.4" TFT Widescreen monitor. is this a stuck pixel? a dead pixel? or another problem completely?

another thing is that the line doesnt stay purple. on black screens and desktop it is purple, but on IE it is yellow, along with many other programs for some reason

i really need help on this guys... ive tried the method on wikihow and ive been trying the JScreenCleaner (stuck pixel sweeping program) but no luck so far...


edit: forgot to say that i know that this isnt a video card issue cuz i plugged it in another monitor and it didnt have that problem. i just really need to know if this isnt something that needs factory repairs cuz my warranty is worn out

A:Purple line on my laptop screen

Attach an external monitor to your PC. If the problem continues there, it's your graphics card.
If the problem disappears, you have stuck/dead pixels.
You could try a very gentle rubbing of the pixel(s) concerned, but it looks like you might need a new LCD-panel.

My laptops are made in China as well, but they are extremely sturdy (IBM, now Lenovo).
