Laptop screen problem (VERY ANNOYED)

Ok, I have posted about this problem on here before, but it has gotten to the point where it is driving me crazy.

I bought my Lenovo n100 a couple of months ago and havent had any problems with it except for one. There are horizontal lines that move up and down on certain colors. They aren't very defined, they just look like static. They show up on grey and blue colors such as my profile picture on facebook which is my face inverted, or on the blue sides of the screen on word 2007.

I have LITERALLY sent in my laptop to Lenovo about 5 or 6 times. Once they replaced the screen, once they replaced the "planar card" which included the video card being replaced (at least thats what they said over the phone). A couple of the times they just updated the bios. The last time they told me to send it in without the hard drive and I got it back with a slip of paper saying they couldn't do anything without the harddrive.

I STILL have the exact same problem. I can not imagine what it is. If it is something Lenovo can't figure out what could it be. I'm going insane.

 

Do the lines go aways when you switch to battery power?
If it does, then its probably a "ground loop"(google it).

You can get a HUM X ground loop eliminator ( http://www.powernotebooks.com/category.php?catId=143) that will usually remedy these things.

 

Any chance you could take a shot of the issue with a digital camera? Also what screen exactly is this? 14/15? Glossy/Matte, resolution?

 

I will look into your advice Kadawka.

And the screen is a widescreen glossy 15 inch I believe.
