The purpose of this guide is to explain how to replace the upper LCD screen in a Nintendo DS. Replacement screens can be found at https://gadgetfix.com/category/nintendo-1526.html or https://www.amazon.com/Nintendo-3ds-Top-Upper-Screen-Replacement/dp/B008174OP6 . All tools needed to fix the screen can be referenced or bought in the tool section below. Care should be taken when removing and moving the ribbon cables to make sure not to tear, break, or damage them. Care should also be taken when the screen is removed from the case to make sure not to tear, break, or damage the black and red wires connecting the two circuit boards. Damage to either of these components might not be able to be fixed and will not be covered in this guide. To prevent damage to these components, the proper tool must be used.
