My uncle sold his DSi to my cousin. Welp my cousins barely 8 and one day he got mad and threw the DSi and hit a wall and when they looked at it the DSi's two screen had a large white strip about an inch or so thick on the very right side. The thing is the touch screen still works and the games still function. Now... I mentioned to them that they could easily buy new screens and replace them but when I found out the screen still worked I wondered if maybe the connections became loose? or maybe the screens really are messed up? what do you guys think?
