Having problems with your Dell Inspiron 6400 Notebook ?

Vertical lines on my lcd laptop screen

\015 I have a Dell Inspiron 6400, and about a year ago I sent it into Dell and had my LCD screen replaced for a pixel issue. Soon after I started to get colored vertical lines that prevent me from using the screen (my warranty has run up and it has been so long I cannot send it back to Dell). The screen looks very similar to this screen: http://www.asklaptopfreak.com/wp-images/color-lines-on-lsd-screen.jpg When I hook the computer up to a monitor or even a projector I can see everything and use the computer fine, the screen remains unusable with the vertical lines though. I put the laptop aside for a few months because I had no idea how to fix it. Randomly I turned the lap top on and it worked perfectly, no lines and no problems. After about a month the computer suddenly washed out and the lines appeared. Saddened, I again put the computer aside for a few months. About three weeks ago I tried to use it again and it worked perfectly but tonight it has washed out and the lines again appeared. I'm wondering if I need a new LCD screen or if it is simply a connection issue since the screen works fine sometimes. I appreciate any help or advice. If anyone has a step by step guide on how to fix a connection issue I would love that. Thanks\015

Answers :

It's the connector problems.
If you know what to do, I can guide you:

First, remove the screw all over the LCD case, then you can see the connector, and flexible cables.
Second, remove the keyboard unit(by removing all screw on the unit), after removed, find the edge of the LCD cables, then you can see the connector.

The solution:
1.Try clean this two connector with soft brushes ( paint brush is good ), by removing the cable first,then clean the flexible connector using wet tissue ( use the alcohol ).

2. If still exist, you need to replace the flexible with new ones.
