Hi,

I'm Ben and -- hopefully -- I can provide some meaningful assistance.

I'm afraid that that the display will have to be replaced. If you want to do-it-yourself, I recommend the following tutorial video.

Hi,

Check the RAM or can change the Ram.
Hope this help and reply for further instruction.\
Thanks.

you have a problem with your screen, if your screen is not good or your cable is not good. but i say this is from the resolution of the screen

You have the beginning of a failing Display panel, and will eventually need to replace the display.. you can hold the top left and right sides of the display screen-slightly bend forward and back, you should see the blue line either go away or it will produce more lines...

This is due to a short on the circuit board panel on the backside of the display panel that controls the Pixels on the Screen.. The Pixels are controlled In a Line Grid Fashion...

You can try changing resolution to something else and then back.
You can see if your colors are 32-bit.
The fact that you "fixed" it is probably an coincidence. Once you start getting anomalies like that, it usually means a new screen.

lcd problem

if u not properly diagnos your laptop this problum will presest, untill u completly diagnos your laptop, other good suggestion is to directly contact with your Warranty Providers.

Good Luck

I have a black vertical line about 3/4" wide with thin border pink, green and blue lines. My cursor runs behind this line but I am unable to find a way to make it just go away?

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 have had the same problem

This happens from overheating or from physically abusing the screen

I have an acer, which can take a lot of punishment, but i throw it around and keep it on 24/7 until it gets so hot the plastic starts to smell and melt

Awesome computer, it still works very well for the price (500$)

It developed blue lines on the screen lately and i know from previous experience acer will replace your screen as this may be a factory problem

If you're a freak like me who runs his computer all the time though, they aren't going to listen to you for one second and you have to deal with it

A) Dont use your computer as much (that sometimes fixes it)
B) Buy a better cooling deck
C) Dont abuse the screen (any bending or even the slightest tap can kill it)
D) If the problem doesnt go away, make peace with it and get used to it
E) Replace the screen (i dont want to, so now i have kewl blue lines on my screen)
