Hi, I recently tried to transfer my DS phat to a new shell, unfortunately when I've just about reassembled everything, the touchscreen fails to display anything. The backlight works, and so does inputting stuff into the touchscreen, unfortunately I can't see a thing on it. Everything else is fine though. I'm sure I reconnected the ribbon cables correctly (they aren't damaged as far as I can see). Does anyone have a solution to this? I'm kinda regretting taking it apart now. Also does anyone know how to stop the buttons from becoming loose? Thanks.
