Is your NDSi LL touch screen broken or not responding well? Here's the cure: the NDSi LL Touch screen replacement module. * Special Warranty: This is a DIY part requiring professional installation. DX can only provide the part as-is because we do not have the tools in-house to QC these things one by one. While there are many customers receiving perfect products there are also reports on defective units. These are Sharp products and all screens are 100% pre-tested by the manufacturer and are packaged in a hard protective carton box for shipment. Should your screen become defective within 1 month of delivery DX will replace the screen for you and you will be responsible for the shipping the product back to our HK office via an online trackable method (buy insurance to guard against package lost while in transit). DX will cover the shipping cost of the replacement shipment after receiving the defective unit. * Important: professional installation required. Please read the warranty disclaimer under the specifications section before purchasing.
