Odd.
Was this from an impact on the screen itself or just it landing on the floor?
I'd think a GPS should handle being dropped, but I could see a direct strike to the screen damaging the screen.
To be honest I don't think it just hit the floor. The TV was on one of those TV stands the have a pole on 4 legs & I'm guessing it must have fell perfectly to hit one of the steel feet. It didn't fall that far or hard.

The crack was in the bottom left corner where the back button is usually positioned. I'm sure if it was in the case it wouldn't have happened. Or if my roommate wasn't a bull in a china shop. But I will take the blame & I will assure you it will never be where it can happen again.
