Toshiba NB200-12N

Hello everyone,
Basically I got this notebook (Tosiba NB200-12N) from my sister and I want to repair it. She had it only for a little while. It has Windows Starter and the appropriate drivers looking at Device Manager but the screen appears with the wrong colours and I can't figure out how can I fix them. Here are 2 pictures of the same screen although the fine picture itself appears so on my other computer but not so on the notebook.





I would really appreciate your help and advices. I really want to succeed in fixing that.
