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 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.

Re: Lines on 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)

Tryconnecting an external monitor to the laptop. You may have to select the videooutput to display on the external monitor by holding down the blue key and pressing the blue CRT/LCD (located on one of the keys, likeF8,F9, etc..). If the problem occurs on the external monitor with the batteryor AC power, then you have a problem with either the video card or motherboardin the laptop. If the problem does not happen using the external monitor thenyou laptop's LCD display is going bad.
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.
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.

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.
