pink lines appear down the middle of the display

Hey i don't really know how to explain this but i'll try.

When i use my MBP every now and then some staticy pink lines appear down the middle... the only way to remove these is pushing the screen back and then pulling it back up slowly.

Does anyone else have this problem ? i've only had it about 3 weeks and i have not dropped it or anything

Take it back & get them to replace it.

Take it back to the apple store. That is not normal.
