both screens have vertical stripes
i have replaced the shell on my original ds as it had a broken hinge, i thought i had done it really carefully but now when i switch it on both the screens have vertical stripes all over them, can't see anything else. i can hear the intro tinkle music but that's it. any help greatly appreciated!
Double check all of your larger video cable connections along with the ribbon cable that goes through the hinge connections. The darker brown piece that goes in the socket should be just behind the white line on the motherboard and parallel to it. The flap that holds the cable in the socket should be even and flat - sometimes they like to bow out in the center.
