HELP! IDK what to do😭

Hi guys😭 My upper screen for nintendo DS lite appears as pink in color and some part of the screen appears as white when I show pictures(it covered some part of the pictures).

When I try to play games, it works, no white parts shown, only the pink color still remains the same.

WHAT SHLD I DO, I FIND NO SOLUTIONS ONLINE😭😭😭😭😭😭😭😭😭
