A line from top to bottom or side to side is a dead or failed pixel sensor. There are hundreds of pixel sensors at the edges of the screen, when one fails it causes a line, the line can be red, blue, white, or black. Unfortunately, there is no way of repairing the line, other that replacing the screen.

Thin blue line


Hi!

This is a phisical hardware problem with the screen.
If the system is under warranty better take back so your vendor replace the screen.

I think is the only solution.

This is a progressive problem, day a day you will be seen more and more lines until the screen become death.

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.

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 :)

Vertical lines in my laptop screen


Hi mikenstacy

Try to connect a normal desktop monitor to the laptop (there will be one vga port where you can connect the monitor) and if you see those lines on external monitor as well then most probably video card has gone bad (you can try to reinstall video drivers in this case) if those lilnes are not there on external monitor then problem is with your LCD so if system is in warranty then get it replaced other wise get in touch with local compter shop and get it replaced.

let me know if this helped

the lcd (liquid crystal display) is damaged at this time, nor the inverter, that is of course inside of your pc, im afraid you need to send this to a repair shop

if this line is there during boot up then it is a monitor problem usually. but if it is not then it is a problem with your windows files. you could try reinstalling your windows from the disks you were given with it? otherwise i will look into it. email me if you need more help. milliprowd21@yahoo.co.uk

LIGHT BLUE VERTICAL LINE ON MONITOR


The vertical line is a bad pixel sensor at the edge of the screen, your screen has hundreds of vertical and horizonal pixel sensors. This is an indicator that the screen is going out and need replacing.

Vertical lines in my laptop screen


There can be 3 possible reasons for this
1)Screen connector cable is loose. You can try to re-seat it and see if works.
2)display card problem. Connect your laptop to an external monitor and see if the problem persists. If it does not then
3)You will need to get a replacement LCD screen.
Hope this helps!
