Nintendo to no longer offer repair services for original 3DS and XL models in Japan
The Nintendo 3DS is getting on in years, and yet another reminder of that is the quiet announcement that Nintendo of Japan will no longer be offering repairs for the original 3DS model along with its XL brethren. After March 31, 2021, Nintendo plans to phase out services for those two systems, as sourcing those system-specific parts has become a challenge. Nintendo notes that even if a 3DS system had been sent in for repairs prior to that date, they still may be unable to fix it, should the needed parts be out of stock. For now, this only applies to Japan, and the original Nintendo 3DS and Nintendo 3DS XL models--the New series is unaffected.
