Question about Dell Inspiron 8600 Notebook

Lines on screen

I have a Dell Inspiron 8600. Just a week ago, I noticed a random purple line going vertically down the screen, it appears over everything (browsers and so on). I didn't think much of it, until a yellow line showed up. Now there are six lines, from purple to yellow. They're thin lines, so I can still see what I'm doing, but I'm afraid that they will eventually fill the screen. How can I fix this?

    I have a Dell Inspiron 9600 notebook. Same thing, colored vertical lines on the screen. Dell and other websites say its an LCD problem and has to be replaced. It can be as much as $500 bucks! I don't know why this doesn't get the press that bad batteries and bad chips get.

    I also have a Dell Inspiron 8600, and I have a single blue, green and red vertical line running down the middle of the screen. I hope someone has a solution, because the computer works fine otherwise. I thought it may be a software problem, or a connection problem. Any help would be appreciated.

    Mty dell 9300 developed a single blue line about a month ago. It's pretty old now (3/12 years) and has seen a lot of action, so I wasn't all that worried. Since then, however, another blue line and now a green one have appeared. Reading the forums on the issue, it seems it's only a matter of time before they multiply enough to block the screen.

    Have a Dell Inspiron 9300, same multi-colored lines. Five of them appeared over the hinges. One disappeared on its own, then was followed several days later by a new one- dead center on screen. I do not agree that this problem is caused by any software as I have added a second monitor and it remains free of lines. This is clearly a defective monitor, and Dell has acknowleged that defective monitors were prevalent from one particular supplier several years ago. It may be too late, however, to ask for a replacement.

I realise that this fix may not work for everyone, but it seemed to do the job for me...
Every time one of these glowing vertical running lines appear, I pinch the LCD surface gently to the plastic backing of the lid and then as gently lift it up and outwards... I apologise if the directions are not all that clear... How better can I describe it? Ahh, I jiggle the LCD within its plastic frame.
Whatever the reasons (contact points, loose cabling) this always fixes the problem, and I don't see it again for days / weeks.
Give it a shot!

My inspiron 9200 had black lines going down the screen the summer of 2007. eventually the lines got thicker and started to block my ability to read anything.

luckily I extended the warranty and the result was that the whole screen was swapped out in October of 2007. the bad news is it happened again -- just today, a little blue line just appeared. here we go again, not even a year with this new screen.

This is a fault with the TFT display controller, Unfortunately this kind of fault is not User Serviceable, If this item is within manufacturer's warranty send it back and they should fix it for you, (REMEMBER TO BACK UP YOUR DATA as they may choose just to replace the whole thing)

Vertical lines on my lcd laptop screen

It's the connector problems.
If you know what to do, I can guide you:

First, remove the screw all over the LCD case, then you can see the connector, and flexible cables.
Second, remove the keyboard unit(by removing all screw on the unit), after removed, find the edge of the LCD cables, then you can see the connector.

The solution:
1.Try clean this two connector with soft brushes ( paint brush is good ), by removing the cable first,then clean the flexible connector using wet tissue ( use the alcohol ).

2. If still exist, you need to replace the flexible with new ones.

Vertical lines in my laptop screen

Try connecting an external monitor to the Dell Inspiron 9300 and see if the vertical line is also present on the monitor. If the monitor display is fine, then your laptop’s LCD display panel is defective. If the monitor also displays the vertical line, then your problem is with either the video card or motherboard located inside your laptop.
Not sure if the Compaq Presario has an external monitor plug, but if it does the above procedure can be applied to that one as well.

Vertical lines in my laptop screen

Many times over years of use the thin canle that connects motherboard to monitor becomes loose very slightly but enough to create these type effects on screen.First easy test would simply be hooking up another monitor to rule out video card.Next would be looking up how to disassemble the plastic trim to expose the lcd cable then carefully disconnecting it then reseating it.If problem still exists wiggle the lcd cable see if it affects lines on lcd display if so then you probably need new cable if not then most likely an lcd screen.
Screens can usually be replaced in about 45 minutes by avg.person.
