I bought 4 broken DS Lites in a bundle for a good price and one of them is missing the top screen, when I try to power it on nothing happens. I tried plugging it in and the orange light will light up and stay like that but still no green light and won't power on. Is it normal that it won't power on without the top screen or there's something else wrong? (It's also missing the volume slider but I'm 99% sure it's only missing the plastic piece)
