Question about Dell Computers & Internet
I suddenly found how pink color vertical lines on dell laptop. On call dell service centre, they say i need to replace the screen. Laptop is only 1 and half years old. Could it be repaired instead of replacing the screen?
You can try to update your video driver from dell at "support.dell.com".
You will need to enter the service tag number of your laptop and follow the instructions to download the driver.

There could be three different possibilities why you would get a line on your lcd display.
First, it could be a missing signal from the controller IC to LCD driver IC
Second it could be a defective LCD driver IC itself
Third it could be a dry contact in the tape carrier package ( TCP).
Attach an external monitor to your laptop and make it your primary display unit to see if you are still getting the lines if not its you TCP if you still get lines it will need to have either the LCD IC or the controller IC checked and possibly replaced.

I know not everyone has this ability, but if you can, go to a friend's
house and hook up an external monitor to your laptop. You may need to
use the function keys to switch from LCD to external, but if the lines
go away on the external, you have a bad LCD. If the line shows up
still on the external, then your problem is either:
a) video driver (free, easy fix)
b) bad inverter (video 'outputter') ...approximately $10-50/varies + labor costs to replace
c) bad video card/motherboard ...usually between $200-$400 + labor to replace
Hope this helps - please be sure to rate my answer :)

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.

Had the same problem. Fixed it though. Here's how:
You'll notice that the screen comes back to life if you press down on the very top of the green line. This is because a controller circuit board behind the LCD screen (at the top) is pressure fit flat-surface-to-flat surface to the contacts on the back of the LCD. Eventually, the sticky substance that holds this circuit board in place wears thin, collects dust, etc.. and the connection between the circuit board and the lcd contact is lost. The line appears where this break in contact has occured.
So, the solution is to increase the pressure at that point to reestablish the connection. I wasn't able to remove the circuit board to clean beneath it as it seemed too likely to cause damage. Nor would I have had the right adhesive to connect it back, so I simply removed the LCD and put a bunch of tape at that point so that it would "push" with a little more pressure when screwed back into place. Worked great.
To remove the LCD, pull off the 6 feet around the screen. Remove the screws behind them. Carefully pry off bezel with a small flathead screwdriver working your way around it. Once removed there are simply 4 screws on the left and 4 more on the right of the LCD to remove. Pull out screen carefully and start stacking bits of tape on the spot where pressure seems to work best. Put it back in and see if you've made any difference. I did this with the computer on so I could verify my results. Just be careful not to short out any naked contacts.
If this doesn't work for you, at least you'll know you just need to replace the LCD, not the video card. Easily found on ebay.
