call Nintendo or visit www.support .Nintendo.com their number is 1-800-255-3700. They are open 6am-7pm western time. Ask about getting an exsisting repair. If you are really in trouble you could become a club Nintendo member and put in your dsi serial number then link your system via a wireless router and get a 90 day warranty.
