Diagnosing LCD Issue: Unibody MacBook

I have a late 2008 unibody macbook that's been problem free so far, however very spontaneously a couple days ago I started having screen issues. Lines will appear randomly (they come and go) which sometimes will go away as I adjust the display. Sometimes the screen will also appear like a negative photo. I took some screen shots of the videos I took when the problem was occurring for reference. I am assuming this is a hardware problem, but I was wondering if anyone on these forums has seen an issue like this before, there are a myriad of problems that come up when trying to search an lcd going bad on a mac. Does anyone have a better idea of what's going on? Thank you for the help.
