Hi, so... Today i got a broken NDS Phat from my friend. So, now i'm thinking that maybe i could fix it. One thing that need repairing is the upper screen (it's cracked). My question would be: what could be wrong with this NDS Phat if when turned on, green light lights up, bottom screen flashes white for less than a second and then powers off. Can this be caused by the faulty upper screen? By the way, it charges nicely. The orange light lights up and stays all the time while charging.
