Question : Problem: Laptop Screen Problem

I have a laptop that has a problem with its screen, the background is white/grey colour with vertical lines (purple/green) in a fixed position. I have tested the laptop with an external monitor and it works fine. Do I need a new screen?

The screen looks similar to the first image on this page: http://www.laptoprepair101.com/laptop/2006/08/17/bad-video-on-lcd-screen/

Answer : Problem: Laptop Screen Problem

No. First of all: I Assume it is an Acer or HP laptop.  It could however happen to all of them.

Now: what goes wrong is this:

There are 2 flatcables running from the computer to the screen.
The cable running from the computer up to the top of the screen has a bad contact. With some laptops you can easy see the problem: The plastic on top of the screen: try to slightly push (squeeze) the plactic from left to right (no rough squeezing!). On a specific point the screen comes up. It is there there is a contact failure.
This happens frequently. I use to "fix" this by removing the plastic from the screen, and put some folded plastic on top of the screen. Reassembling, there is a slight pressure on the contact points, and it works for a long time.
It could be fixed "better", but then you need to return the laptop to the reseller, and chances are high they just replace the screen.
