This usually means that a ribbon cable is disconnected. I would open up the top part of the clam shell, and Check all the ribbon cable. Use some tweezers if needed since you have big fingers. BUT! Be careful, those ribbon cables are delicate, along with the fastener clips (the black clamp where you fasten down the cable). If the cables in the top shell are properly fastened and they aren't damaged, then you might have to check the cables going from the sister board (Top shell) to the main motherboard (bottom shell). Check for damage, and check to see if its properly fastened into the both the motherboard and sister-board. Hopefully you have a Tr-wing bit (or screwdriver) to get into the bottom part of the DS.
