A vertical row of pixels appeared on the LCD screen. Cable, inverter or LCD?
Couple of months ago, a vertical row of pixels was shown in yellow, and 2 weeks ago, a 4cm row of pixels on the right side of the LCD was blurred and after couple of days, it went completely white. Same this is now happening in the left side, and i’m afraid it will shortly turn into white as well.
Can this be caused by the graphic cable or by the inverter, or is this the LCD dying on me…?
By the way, it’s a Toshiba Satellite P105-S6084.
This problem is not caused by the inverter board because you still can see the image on the screen. The backlight still works, so it’s not the inverter.
Also, it’s not related to the LCD cable. A bad faulty LCD cable affects image on the whole LCD screen, not just on a part of the LCD. I don’t think that your problem is related to the cable.
Apparently your LCD screen is dying and you’ll have to replace it soon.
Just in case, test the laptop with an external monitor attached to the VGA port on the side of the laptop. Most likely the external video will be fine. Let me know if the external video output also has vertical rows of pixels. Because if it does (I really doubt it), there could be a problem with the video card.

Matt,
Did it happen just once or you experience this problem every day?
This problem could be related to the LCD screen or video card. In order to narrow down the problem, you’ll have to test your laptop with an external monitor attached. If you are getting the same problem on the external screen, most likely it’s related to the video card. Let me know.

Anil,
That could be memory related problem. Try reconnecting memory modules maybe it’s just bad connection. Test your laptop with each memory module separately. If one of the memory modules is bad, your laptop should start when the second module installed.

a vertical row of pixels appeared on my lcd too, my lap is toshiba satellite m30x, but it’s all, it is only one row, but it rarely mixes on all over the screen, looks like there were only vertical rows of pixels of one color each, and it moves when i move the mouse, sometimes it’s just a second and sometimes i have to reboot my lap top (it happens when i used to play counter strike, like 2 months ago) and then fixes
it happens once in a while, but other else works fine
thanks in advance

I have a sony vaio sz series notebook, a black line appears on my monitor that splits it in half, it started with a small amount of black dots, then it grew to this line! while i’m working on the notebook (i still can see everything from behind the line and around it), the black line become pixels of different color (green, black, blue and red pixels), instead of only black. Also sometimes if I work for like 4 hours or more the line becomes thinner than when I turned on the laptop.
One more important thing, I can see that there is a black line when the laptop is turned off! Does this mean that my monitor is cracked and I need a replacement?
Please don’t say yes, it costs over $700 USD, and I definitely don’t need to go spending money now for a monitor or a new laptop!

Hi,
I have seen many solutions on your page so hopefully this problem makes sense to you. My Toshiba Satellite A200 will not display anything on the laptop screen except for vertical lines.
History: It was suddenly freezing with some screen garbling after movement. I connected it via the VGA and it worked fine that way, sometimes even without the monitor hooked-up.
I ran the recovery disks in case it was software and set-up vista home premium stock. No problems while using the monitor.
Then the next day suddenly the laptop screen showed vertical lines right from power-on. It wouldn’t even show the toshiba screen with set-up entry keys. Just shifting colors of black/ grey with vertical lines. No picture is displayed. I can hear Vista boot because of the “vista song”.
If I hook-up the monitor, I can boot in safe mode and get a display on the monitor only, with lines on the laptop screen.
In normal mode, with the monitor hooked-up, it loads normally on the monitor (showing vertical lines on the laptop while monitor is fine). Then after the little windows bar with moving lines, the monitor shuts off and the laptop display remains black with vertical lines. Windows vista song can be heard then. No screen change.
It only displays perfectly in safe mode now on the monitor.
P.S. It has had some rough treatment. The plastic at the bottom of the screen is cracked (but not the screen itself)
What do you think?

I have a Compaq Presario r4000 that was dropped. Since then, the right side of the screen has a band of vertical stripes, about 4 inches wide and running from the top to the bottom. The band is always about the same size, but changes color. It is not affected by pressing on the screen. I plugged it into my desktop monitor and the picture looked fine, so I figured the screen had to be replaced. I got a new screen with a new video cable and inverter board and installed. I just turned it on to see the same thing happening. What can I do?

Omar (#7), I’m having the same problem I think. I have a Dell M1330 that I bought 18 months ago, I’m getting two changing-width line-like clusters of what look like dead pixels vertically up my screen near the centre.
I think only some colour-parts are not working tho, because when i put different colours behind the lines, some go away, like you say. Also, when i power-off the laptop i can still see the affected pixels when i shine a light on the screen, they relfect differently to the rest of the screen.
I would go with physical damage as you say, but in my case I was using the laptop with no trouble last night, turned it off (hibernated) and left it with lid still open over night. This morning I came to turn it on, and the lines immediately were visible even in bios. And i hadnt even closed the lid or moved the computer overnight. Very weird.
LaptopFreak, any ideas would be greatly appreciated!

A couple of days ago my Toshiba Satellite A205-S5841 was handled incorrectly by someone. They closed the lid and had their hands on the screen and the pressure caused it. You can touch the screen with your finger tip and move the lines, etc around. Now I have a few long thin lines of colors black, grey, white, light/dark blue, brown, and a lime green. The lines are only appearing on the right side of the screen. The middle on the screen has a few ink looking blobs and a spider looking crack at the top of the middle. The top left side of my screen shows my desktop normal for that area like it did before this happened. I have a transvideo cable hooked to it and use my TV for a monitor meanwhile. It works great on my TV. Also the outside glass of the screen is not damaged at all. With everything I have researched on this topic could a cable be loose or do you think the screen will need to be replaced? Thanks so much!

RE: Dell Latitude C640 14.1″ XGA Display
I recently acquired a used Dell C640 off of eBay. The display does not work but the laptop drives an external display just fine.
When I disassembled the display assy, I found that the inverter plug had been separated from the ribbon cable … the seller fessed up to the botch when I asked specifically.
I just received & installed a used replacement flex cable. I put it all back together just enough to mount it, loose, on the laptop chassis and cranked it up.
The display works … to some degree.
The right ~25% of the display is black because the desktop is compressed towards the left. Vertically, the bottom ~third of the desktop ghostwraps around the top, images still in proper orientation (upright), btw … and all visual components on the desktop sport ghosts just below them, including the mouse pointer.
Can anyone here explain the possible cause(s) of this so that I may take steps to correct it?
BTW, I have tested this laptop with another Dell 14.1″ XGA display assy and that one works as it should, so the cause(s) is isolated to the actual partially-assembled display assy.
Thanks!

Kim,
Did you test this LCD with your new video cable? I’m thinking maybe the video cable is defective or not compatible with your original LCD screen.
August 13th, 2009 at 4:03 am
No, the other display assy is a complete, drop-/plug-in, unit.
My initial thoughts on this mirror yours, that this ribbon cable is either defective or not the duplicate that it is supposed to be.
Thanks, LF … I will contact the Seller.
August 17th, 2009 at 1:37 pm
Unfortunately, it was not the cable.
With a brand-new-never-installed cable I get the same results …
I even tried it on a different laptop … No Joy …
August 17th, 2009 at 10:12 pm
Kim,
So, it’s not a connection related problem. It’s not a cable related problem. The laptop works with another LCD screen.
I guess the LCD screen that came with your laptop is bad or cables you are getting are not compatible with the original LCD.
August 18th, 2009 at 4:30 am
Ayup … and since the ribbon cables bear the same part & revision numbers I have to assume that the fault is with the panel electronics.
I have sourced a replacement and it is inbound.
Thanks for you kind assistance!

Hi everyone,
I have a Del Inspiron 9400 laptop and a few months ago two very thin (one-pixel-wide) vertical lines appeared to the very left of my 17 inch screen, one green, one yellow. Since it was a minor nuisance I ignored it. Week by week, one or two more would appear gradually more and more to the right. then yesterday night after watching a moview and when the black screen at the end came up with all the credits rolling I closed the moview window and suddenly a huge white band about two inches wide appeared in the very middle of the screen.
I plugged in my laptop to an external monitor to see if my video card had died, but the image was fortunately/or unfortunately clear/normal. Is there a way to fix his? or do I have to buy a new monitor? If so, where can I find a cheap monitor to install it myself, it is very easy, I’ve done it before. I tried ebay, but there is nothing. I called Dell, but they only sell sch parts with a technician who must come to my house, or I must ship my laptop, both of which are out of the question for me, the first due to paying an unnecessary price, the second because they always mess up my files or erase my drives every time I’ve shipped my laptop, be that to install a new cd/dvd driv, or change my RAM, no matter how many times I told them not to touch my data.
Right now i am using only the very right side of the screen, but I fear it won’t be long until it dies too. I opened the laptop and checked the connection to the screen and the cables, and there was no change…

dmppdks,
You have a failed LCD screen. This problem cannot be fixed. You have to replace it with a new LCD screen.
You can replace the screen yourself, here are instructions for you.
How to replace faulty LCD screen in Dell Inspiron 9400.
Did’d find a new LCD on eBay? That’s strange. There are tons of them.
You’ll find a link to new LCDs in the same guide I mentioned above.
Good luck!

i connect my laptop from tv and find screen on tv but on tv it is very dull,no colors ,no sound.How will i get it?
May 17th, 2010 at 3:09 pm
my laptop screen is showing a bunch of horrizontal lines of white. its every second or third line of pixels it seems. is this my screen dying or is it something that i can fix. it is not a virus, i have done multiple scans, and my laptop is working fine other than this.
September 29th, 2010 at 3:57 am
Hi there… I’m pretty sure that my laptop needs a new LCD thanks to your guide. Thankyou.
I’ve had this set of horizontal lines accross the bottom of my Dell XPS, slowly consuming more and more of the screen (especially after dropping the laptop once). THe colours also change in these lines as the with the general colour display of the rest of the screen…
