Now I get it, I thought we were talking about a rather small crack near the edge of the display. But still: you can't see that crack from outside. This makes the whole situation very dubious. It could also have happened after focus gave the M92 to the parcel service. At the moment it looks like Booxtor is right, since there definitely _is_ a big crack and it definitely looks like caused from pressure on the surface. It's unlikely, but it's not impossible that the screen had a different problem and the crack occured later, e.g. after handing it over to the parcel service...
But now it's maybe the right moment for another statement of focus.
