Reseat the video cable connection under the keyboard, and see if the lines go away. If not, connect an external monitor, see if the lines show there. If the lines do not appear on the external monitor, then replace the LCD. If they do appear on the external monitor, replace the motherboard

My dell lcd screen some lines vertical problem


We might be having issues with the video card or the LCD
For us to isolate where the problem is coming from
1. Tried accessing the BIOS see if the vertical lines are present
2. If there are vertical lines on BIOS definitely the problem is LCD and we to replace it
3. So if we see vertical lines inside Windows we might have issues with Video Card itself or Video Card driver
4. Try uninstalling the video driver and install a fresh copy of video driver. Else we need to replace the video card
5. Usually laptops have integrated video. So we need to replace Motherboard

One narrow vertical red line constantly on screen of Inspiron 6400 running Windows 7.


Check on another external monitor, if the picture is ok there, eliminate a faulty graphics chip
If picture is still poor, Graphics chip is faulty

You are now left with the issue of it being the VGA cable from the mobo to the screen, or a faulty screen. It may be that you just need to have the connections checked, but also may point to a replacement screen or Cable being needed

Vertical lines on my lcd laptop screen


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.

Dell Inspiron 1501 Laptop-6'' Red Vertical Line


The color red and especially red colored lines or a pinkish hue are indicative of an impending screen failure. The only other possibility is that the data cable on the left backside of the lcd panel may be loose at the socket or on the motherboard. 9 times out of 10 though, it is the lcd panel that it failing.

Vertical lines in my laptop screen


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!
