Laptop Display Help

First off, sorry if this is the wrong section. It seemed relative to my problem, thus I posted this here.

My laptop (Click here for Specs!) has a problem with the screen. On the right hand side of my screen, there is a column about 2 - 3 inches which is white with different colour lines running through it and a block of black.

I don't know what caused this as I had the screen replaced in about November of last year. I can still use it for everyday things such as social networking and reading articles online but it is becoming an inconvenience that I can not view anything when opened in a full window. Films are particularly annoying to try and watch as I can't have them full screen. I can no longer play games like Football Manager either, which is particularly disappointing as I've not long had this game.

My first thought was perhaps I have accidentally stood on my laptop thus causing this on the screen. After reconsideration, I concluded that this isn't plausible as the column is perfectly straight and there is no crack like markings on the screen.

Alas my next thought, maybe a wire has come loose behind the screen of the laptop? I'm not sure as I've not looked and I have no experience with opening up laptops. I've looked at videos online on how to do it but thought I would ask here where, without a doubt, you guys would have more knowledge on the subject than me. If this was a desktop it would be a whole lot easier as I have a lot of experience with them and the maintenance of them too.

If you can give me any clues as to what the problem might be and/or how to solve it, it would be very much appreciated.

Thanks a lot!
