Built-in screen not working

[GabHasABrokenPC]

Recently one of my backpanel screws came loose, the left hinge that was previously held by the backpanel, was now floating. From my observations the left hinge didn't have any screws on it. This issue was unsee until now because the backpanel is made of metal and was able to hold it. I believe the screen cable came loose in it's connector or the cable got pinched, because the screen sometimes work or doesn't. When it doesn't work, It doesn't show up on the device list, and I do see it when it works (checking from an external monitor). Could the problem be something else? Would this repair be covered by the legal warranty? 

I have attached a picture taken right after the backpanel was removed. See how the hinge on the bottom right has no screws.
