Dropped DS Lite?

my nephew dropped my ds while it was open. it dropped with both screens facing the floor and there was a game going on. i turned it off and took the game out, then i restarted. the top screen was fine but the bottom showed white with vertical lines. i tried restarting and recharging it for about half a day and nothing worked. is there anyway i can fix it without having to pay 75-85 bucks to get it repair/another? from disembling it to going somewhere to get it fix? please help, thanks.
