Thin horizontal white stripe on laptops LCD

Dell INSPIRON 1520

Specs: Windows XP
Hello guys. So I have just got one problem. I have a bad feeling about it... I've been playing game (ARMA II) and then, suddenly a white horizontal stripe on my laptops LCD appeared. It is white but at the edge of monitor it is a bit darker at fades away in distance (Similar to stripe in Windows greeting window). The stripe devides my screen in 2 almost equal parts (the part at the bottom is bigger). Reinstalling drivers didnt help, neither reboot. I should also mention that my laptop was once spilled with bear (4months ago) and I had to get my motherbroad be fixed. It worked fine for 4 months until now. I didn't drop the laptop, I didn't open it. So what might be wrong??... Thanks for answers in advance. Sorry for my English, I'm a bit pissed of with this problem, no time to think about grammar ;(

Could it be that it was always there? Dell/sony had that issue for a while. Said it was a design.

Not much you can do. Some might suggest you try to reseat cables but it carries some risk or further damage.

If it's there all the time, it probably can't be anything other than the LCD display's circuits are damaged. Driver problems don't cause single lines.

You could try connecting a monitor to your VGA port, but it's likely the video on that will be fine.

See response 1:

See your Owner's or User's manual for your model to see if there is a key or key combo you need to press to enable the VGA port to enable a display.

E.g. I found this on the web....

"On Toshiba laptops you can toggle between internal and external screens using Fn+F5 keys. Hold down Fn and press on F5 until you get video on the external monitor.
On IBM laptops use Fn+F7.
On HP laptops use Fn+F4.
It’s possible that you have to use a different key combination on your laptop but you get the idea.
On some laptops, in order to be able to use the external monitor, you have to connect it to the laptop and then restart the laptop so the external monitor is detected by the laptop."

NOTE - monitor video cables are NOT "hot-pluggable". DO NOT unplug them or plug them in while the computer is running !

By the way, when I press ctrl + print screen and paste it into the Paint, no stripe appears to be in that screenshot.

So this problem is caused by some kind of cable "stuff" or "damaged displays circuits"? How serious is this one? And yeah, I'll try to connect another monitor (looks like I'll have to press fn+f8 (crt/lcd) buttons)) as soon as possible. Another question would be, if this might have smth to do with spilling liquid on laptop and fixing motherboard?

What is more, I was moving my laptops LCD up and down a bit and 1 time it blinked. Don't know if it means anything but maybe there is something to do with cables?...

"...if this might have smth to do with spilling liquid on laptop
.."

Could be - did you get on the display assembly ?

"...I was moving my laptops LCD up and down a bit and 1 time it blinked..."

Damaged wiring between the base and the display is common, usually it's damaged where it passes through the hinge, but I haven't heard of it causing a single line to appear.

Connecting a monitor to the VGA port will show you whether it's a onboard display adapter problem - it probably isn't.

"Could be - did you get on the display assembly ?"- No, the liquid was spilled only on the keyboard. Also, the guy who fixed motherboard said the monitor was not damaged. So I still hope it is something about cabels and can be easily fixed... :/

"Connecting a monitor to the VGA port will show you whether it's a onboard display adapter problem" - You mean if it is problem with LCD monitor? I'm going to try connecting on Monday, haven't got an opportunity to do this earlier. By the way, thanks for responses I really appreciate this :].
