Hi Lorena. I'm sorry to hear about your DS lite. I don't understand how the bottom screen could be preventing the DS from turning on. If the bottom screen was defective, you would at least hear sound when the DS is powered. You may have damaged the logic board or some other component. But if you're looking for replacement parts, this [link|http://www.dealextreme.com/products.dx/category.604|link] should help you get started. Good luck.
