Question : Problem: Screen Fuzzy

While on the floor at a school function - daughters laptop may have been bumped/hit by a bouncing ball or a person's foot.  "Nobody saw what happened".  Immediately following the event her screen became fuzzy with red horizontal lines scattered throughout.
All programs are funtioning just harder to read.
For a brief 10 minute period a few weeks ago - the screen fixed itself but when back to the fuzziness.
We have connected laptop to a regular CPU snd it works fine.
If there is a loose wire in the top of the laptop, can I fix it or where do I need to bring it.
