Either your lcd screen is bad or the video card inside the computer is bad. To isolate the problem try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok then the video card inside the computer is good, but your lcd screen has a problem. If the Borrowed monitor displays the horizontal lines like your lcd screen then the video card inside the computer is bad.

The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

Montor is blured with horz lines


The monitor or lcd screen is probably going bad or the video card inside the computer is bad. To isolate the problem try connecting an external monitor to the laptop. Borrow a Monitor from a neighbor, friend, relative or co-worker and connect it to the laptop. If the Borrowed monitor displays ok without the blur and lines, then your lcd screen is bad and the video card inside the computer is good. If the Borrowed monitor displays the same way as your lcd screen with the blur and lines, then your video card inside the computer is bad.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

My dell inspiron 6400 has small horz line on screen


If you have tried this with an external monitor (and the line is not there)
then the problem is either the connection on your display cable or (more likely) a fault on your LCD panel. If it's still under warranty I would let Dell take care of it.
If you want to do it yourself, you need to get a replacement LCD panel, take the screen apart (the top half of the laptop) and switch out the LCD panel. Some small Phillips head screwdrivers are required, the screw heads on hinges etc. are tiny.
While this is not an overly difficult process, it may prove daunting to some people. Most computer repair shops like mine would charge $30-45 for labor on this plus the part, which according to ebay will run about $75. Make certain you get the correct size, as there was a 14.1" and a 15.5" model (They are not interchangeable). Screen size is measured diagonally across the actual screen and does not include the trim.

Dell 2001fp - Ramdom horz strips


Just had the same issue with the horizontal lines. In my case, too, turning off the monitor would make it go away for a while. called Dell, turned out it was still under warranty (3 years), got a replacement monitor the next day. Way to go Dell!

Re: ask assistance


caution reduce brightness to protect crt burn. vertical line with sound ok is due to 1 deflection coil connector loose or wire going to horz.coil disconnected. 2 capacitor going to h/winding loose or defective. 3 print break from eht to h/coil.
