Are these lines showing up on the LCD & or on the resulting videos? I've noticed with mine that if I film in dark conditions, the HD quality is lower with lines or artifacts in the video. Otherwise, you may need a new LCD, but if it's not affecting the resulting videos, and you can see to film using the LCD, you can still use it as is.
Either you can hook up an external monitor or access BIOS setup (Basic Input/Output System) to replicate if the horizontal line appears. This step will check if the problem is with the video card or the LCD.
If you get the horizontal line on the BIOS or never get it on the external monitor, then surely the LCD screen is beginning to fail. You need to reinsert and/or replace the LCD inverter or LCD itself.
However, if you see the horizontal lines on the external monitor but not on the BIOS, try to update the video driver. If this will not resolve the issue, you need to replace the video card or the motherboard of your laptop.

Line faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD & Plasma screen are similar, irrespective of its brand and screen size
Sticking shutter. It will require either cleaning or replacing.
lines on photo's are due to the shutter sticking.
the video function does not use the shutter so is un affected.
Connect an external monitor to your lapotp. If the problem persists on both display in the same time it means you have a defective video card. If the video signal is not affected on the external monitor it means your screen/inverter is defective.
Expensive to fix it in both situations. Have it checked by a professional.
We have many problems with loose or poorly seated cables and connectors on these units. Pull the back and reseat all the internal cables, especially the LVDS cable to the LCD control bd. If this does not correct the problem the main cause is a bad LCD control bd. or possible a defective main bd.
