I get very narrow Cyan vertical lines across the entire screen
I have a Toshiba Satellite P35-S6292 (a wide screen laptop) and this has been happening for a few months now. I get very narrow Cyan vertical lines across the entire screen. It comes and goes constantly. I thought it heat related but it does not appear to be.
It will come and go constantly. Tipping the laptop, twisting or otherwise pulling up on the screen. especially near the hinges will make it come and go, as will tapping anywhere on the keyboard surface of the case.
It would appear there is something loose somewhere, thought it does not appear to be due to broken hinges as the screen has no problem staying up.
I am frustrated beyond belief and cannot find anything else anywhere on the net.
Your lines look like in the example 2 here? Test the laptop with an external monitor. If the lines appear only on the internal LCD, most likely you have a bad LCD screen. By the way, you can find some disassembly instructions for Toshiba laptops here. There are no instructions for taking apart display assembly for a Satellite P35 notebook, but there are a lot of guides for other models, they all similar. I’ve added display disassembly instructions for this model.

My Toshiba 17 laptop has had some issues lately. I took it to best buy and the geek squad didnt fix it. What they did do was sold me $791 worth of stuff and now my laptop looks like its on life support. It crashed (shutting off) while I was in Second Life. Now it over heats alot and shuts off allthe time even in simple games. Since Geek squad had it, Jr, (the lap tops name) Jr, weghed close to 18lbs when I got him back it was like he was on a diet. His optic drive doesnt work the sound card sputters, and now I have cyan (first started) then came red and now green then royal blue and now white & yellow and darker green vertical lines are on my screen its like looking at things thru a jail cell. Aggrivated isnt half of the words I would like to use. Its been swept for malware & viruses, and its continually doing the same thing. And it is getting the better of me I am SO ready to fling Jr acorss to the wall like a frisbee. BUT I love him, and I am attached to him. HOw can I fix him without going back to best buy’s geeks and wring that %^&*()(*& hard drive for ruining Jr ? Thank you Laptop Freak in advance, I appreciate any help

I have the same problem “Cyan line(s) on the screen”, the Machine is Dell so its not only Toshiba with these problems…however its manufactured by LG. Will someone please post a solution to this problem and not necessary replace the screen…. that would be really helpful

Manos Var,
The only way I know is replacing the entire LCD screen.
Is it only 10 months old? Probably you still have warranty. LCD replacement should be covered.

I have a Toshiba Satellite M60, and the same problem with a lot of people, vertical lines 1pixel wide appearing on my screen. First it was just a line then 2 ,3 , you get the point! Now, after about 10 months of use, 45 lines and going!!! External monitor works fine.
Is there a way, besides replacing the lcd screen, to fix this?
P.S. This thing with the vertical lines is a really common problem. Shouldn’t Toshiba deal with it accordingly?
Thank you in advance!

I have a Dell, XPS M1210 laptop. Recently we had one or two very thin, horizontal lines appear at the bottom of the screen above the task bar. It seems to be spreading as we now have about 10 horizontal thin white lines at the bottom.
Any idea what this is and how we can fix it? I worry that soon it’s going to take over the entire screen.
Thanks!

Hp has been having some problems with their screens….does is work when open less than 85 degrees? Is your machine under warranty? Send me an email to sungraphics@aol.com and I can give you some other guidance on this matter. Chris

I have an HP Pavilion dv9500 17″ monitor. I have been having cyan horizontal lines and also some other things that are hard to describe. This happens when the screen is open more than 85 degrees. It just started and we are not sure if we should take it to get looked at or try something here ourself.

is there a way to be sure that lcd will work fine (eg replace this, this and this and it will work fine)
December 15th, 2007 at 4:24 am
hello again,
I’m on my 4th lcd
December 12th, 2007 at 2:10 am
regarding Christopher p35
I also have a p35. At 10 months the inverter had to be replaced. It overheats, the dvd usually fails to recognize new dvd for recording, the battery, fully charged, lasts for around 10 minutes, counting the orginal lcd, I’m on my 4th lcd and this one has also developed vertical lines. This current lcd is less than 1 and 1/2 months old. I’ve had it with this Satellite. If you hear of any class action suit, let me know….thanks

I had the same problem with my Qosmio G20 laptop which is now about a year and a half old.
About two months after I purchased it there were several black specks of dust in the monitor… I sent it back to Toshiba and they cleaned it but about a week later the dust reappeared. I couldn7t be bothered to send it back so lived with it.
About 4 weeks ago I noticed a thin blue cyan line on the right side of my monitor so I sent it back to Toshiba. they told me it was a result of the dust in the monitor (which was left there by them during the initial fix so repaired it at no charge.
Two days after getting the computer back the same line appeared again and with it another line on the left hand side. Quite irate and off to Toshiba for another week I just got it back this morning and seems to be working fine but given Toshiba’s track record so far I don’t know. I’m keeping my fingers crossed

also few things that might help the diagnostics…
randomness of appearance of that line is not connected with OS/s resolution of the screen etc… i am pretty sure that some hardware problem occurred – i am hope that there is the chance that monitor is fine but that there is some connection problems. when my lap is on for some time line does not show – at least for now.
October 21st, 2007 at 1:43 am
hello 2 all,
probably i am late…
most unfortunately yesterday the cyan vertical line appeared on my toshiba p30 laptop (about 2/3 of the screen from the left side)
that line is currently not on my screen but when i turn on the computer it appears and dissapears randomly
when line is not present on that vertical monitor works as usual – fine. and when line is present monitor also works perfectly except that line on the screen.
is there any chance for me to fix anything
thanx

Houston,
If you search here for “P105 screen” you can find one for about $165, I think it’s a good deal.
Sounds like a problem with the screen itself and it’s not related to the video card, connection or overheating. I would say this is the screen problem.
By the way, it might happen with any laptop not just Toshiba.

I have a Toshiba Satellite P105 with 17″ display. 13 months old and I guess 1 month out of warranty and a line has appeared today from top of display to bottom, about 4 inches from left edge and probably 1 pixel wide.
Looks like $420 for a new display including shipping, if I replace it myself (from http://www.screentekinc.com/). Any suggestions for alternatives appreciated.
I don’t know for sure at the moment if it is the display, or maybe a connector or graphics card. I’ve restarted after allowing 2 hours to cool down and still present, so not likely to be a thermal problem. Will try connecting an external display in work tomorrow, and I expect it will be fine.
major bummer. No more Toshiba for me. Dell appears to have best value for money and best support.

I have a Toshiba P30-135. Same problems. Every few days another vertical line appears. They aren’t all the same color. The line that appeared yesterday is green. It flashed on and off at 2 second intervals before becoming permanent today.
I had the heating problem too: shooting compressed air into the fans at the bottom and the grilles at the back seems to have solved that one. For the time being…
September 14th, 2007 at 9:54 pm
Another P35-S6292 owner, with overheating and vertical lines on the screen. I did manage to cure the overheating with canned, clean air.
What a hunk of junk. First and last Toshiba.

yes I know but where i live the screen costs about 300usd so its expensive and my warranty period has expired from may.before 2 days of this problem my screen was perfectly normal it was working really well but i decided to paint the front cover so i dissassembled the cover and finished the job, after i had painted it i put it back on, but, after five minutes the vertical line appeared,can there be something loose?like wires or cables.
Thanks for your help…

Ghassan,
Sounds like a problem with the LCD screen. I think you’ll have to replace the screen.
September 10th, 2007 at 12:10 pm

I think this is just a faulty screen. This problem could happen with any other laptop from any other manufacturer.
September 9th, 2007 at 12:04 am
My Toshiba laptop has the same fauly as that of Chris. All the right hand side is covered by lines. Do you think that this is a manufatured error of Toshiba?
September 5th, 2007 at 3:50 am
Just fixed mine!
Sorry, you’re all wrong. For future reference, this can’t be a virus; viruses are software, and bending the laptop is not an interface maneuver. The computer has NO idea you’re bending it, so a virus cannot detect such a thing as an “event”, so to speak (I bet tons of ubergeeks are flying in a roflcopter right now)
This is what’s happening. There’s a contact in the back of your LCD that is being made that shouldn’t be. Remove the rubber things on your screen, those will reveal some screws. Unscrew the thing, and then slowly snap off the front cover, exposing the LCD screen.
(If you’re not careful you’ll break the screen, but hell, who cares the screen sucks anyway–buy a new one and leave your comp disassembled in a safe place and you can just plop the new one in)
Now, if you’re an expert with hardware, you can somehow figure out a way to relieve the offending area without doing something stupid like I did. What I did is jam a few business cards I had handy into the offending area.
Keep in mind that if the colored lines come back, you’re gonna have to do some more adjusting. If you tell your technician specifically this solution they might be able to take care of the problem at a lower cost by squeezing out some sort of glue in between the offending contacts
It should be a part of the circuitboard in the same place as your offending area(s), but if not, just poke around with a pencil and see what it does. YES, you will have to do this plugged in and turned on! But don’t worry, it’s just a screen, see above if you somehow are crazy enough to fry the screen!!! When doing this, you should be looking for areas that make it WORSE when you do this–this is because the offending areas will get worse when further contact is made, so you gotta try and force that to happen. if you make it “permanently” worse, don’t worry, you can always jam some more business cards, or improvise, come up with your own solution
Now if someone could only tell me why my old Acer gives me direct read/write errors on whatever hard drive I throw in!
