Instructions
Check the warranty period on your Nintendo repair warranty paperwork to see if the time between the date you purchased the product and the date of the issue's appearance is within that period. Your warranty coverage is void if the issue occurred outside the warranty coverage period. Games and accessories usually have three months of coverage, and most devices have 12 months, with an additional three months for Wii consoles and Nintendo DSi units registered online.
Consider the device issue. If you're dealing with a product technical problem within the warranty period that isn't the result of a liquid spill, tampering or use of products not approved for use with the device, and the issue doesn't involve scratched discs or a cracked screen on a handheld, your warranty is still valid. The exception: if you removed, altered or defaced the serial number on the product, no matter the issue, the warranty is void.
Contact Nintendo Consumer Assistance at 800-255-3700. Ask someone to help you better understand your warranty coverage or ask for assistance with troubleshooting your Nintendo product. If your warranty is void and phone-based tech support isn't available or won't work in your situation, ask for information about the closest Nintendo Authorized Repair Center.
