Odd Screen - Random pixels, gets better when front plastic is taken.

So, basically, the chromebook was hit by a piece of wood (my bed collapsed).

After turning it on, the whole screen was out of focus, with random colors and patterns forming, but after I removed half of the front plastic carcass (the top half), it somehow realigned itself and was perfectly in focus. I immediately made backup of everything and ran some tests - everything was OK.

I decided to return to sleep and turn it down, the following day, once again everything ran fine - and as soon as I closed the plastic I had the same problems as before. To my surprise, removing everything made matters worse, and now I can't get the screen to work properly on the previous position.

Anyone ever heard of a similar problem or could shed some light? I am worried about simply buying another screen since it worked perfectly this morning.
