Vertical thin linings on lcd monitor

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

I had the same problem - sent it in to Acer and they replaced the LCD for 500 bucks!

This could be a failure in several areas along the path from the video card to the monitor.

Being that there is not an issue across the entire monitor the video card should be considered a last resort check.

Usually this is caused by a loose connection between the LCD driver and the LCD panel itself. Sometimes light pressure applied near the affected line will clear it up. If that does then it is a connection between the LCD panel and the connector to the LCD driver at the panel's edge.

Not much can be done unless you have it repaired by a professional or you can take it apart yourself and apply a pad of some type inside the monitor's edge to apply the needed pressure once assembled.

problem in vertical section.

1. Solder the vertical ic

2. vertical ic supply capacitor problen.

3. dry points in neck board.

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!

Hello Monastirion,

Is the red line there all of the time without exception, for instance when you initially turn on your pc, is it there before the operating system boots?

If so, the monitor itself is most likely broken. I would return it to wherever you bought it, if possible.

That means the LCD panel itself (the actual glass) is broken. Don't delay, return it and get another before it's too late! The problem will most likely NOT go away, and there is no fix other than to replace the panel itself. The panel, when purchased separately, can cost more than the monitor itself.

The LCD would start to fail eventually, there is a fix you can try which has worked for some, but it solely depends if you want to try it out, it might revive your LCD...

It is due to immense use of your laptop. So dont worry, off it for some time and on it again. It will not come. It is the same problem i m facing with my laptop. All the best.
