DS Lite freezes when shaken

Hi, I have a Nintendo DS Lite with a problem. Sometimes when I try to turn it on, it shows a green light but there’s no image on the both screen. But when it does turn on, whenever I try to lift it or shake it slightly, it freezes and and I try to turn it off/on again, it shows the green light but the screens aren’t turning on again.

Edit: It seems to freeze instantly every time I press hard near the lower touch screen area.
