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.

Two possibilities are there. The first one is, with loose LVDS cable, that connects the T'Con board to display panel. The second is the fault with its main digital processor board. http://electronicshelponline.blogspot.com/
Check the main filter capacitors at its power regulator board. Replace if found bulged or damaged. Replace all secondary side supply rails' filter capacitors too. The fault is with damaged electrolytic capacitors at the power regulator board itself.
IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........
ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER Hope this will help in solving the problem.....
sounds to me like a broken lcd screen. Check if it works on external monitor, if it does the problem is your screen. If it is the same on an external monitor then the fault is with the onboard graphics card. This should be fixed under warranty
check the display on exter monitor through the vga port, if its there then its the fault of the screen, if its not then its the fault of the motherboard of laptop take it to the service centre
To determine if you have a faulty LCD screen or a faulty video card, connect an external monitor to the laptop's video port, power up the external monitor first the the laptop. The video output should automatically switch to the external monitor. If you get a normal image then the video card is OK, and the fault is with the LCD screen.
If you still get a bad image, then the fault could be a faulty video card or video RAM. Most laptops use part of the main RAM module for video RAM, try reseating the RAM modules and or test the RAM modules. If the RAM is OK then the fault is the video card.
you will need to check the display cable and if that is ok, you will need to replace the display panel... You're getting a short on the circuit board causing rows of pixels to be blocked out
