RBR50 Suddenly Stopped Working

Hello,

On 1/8/2019, I purchased the RBK50 Wifi system from BestBuy in Michigan, USA.

I gave the system to my parents, and they took it back to Taiwan (where they live now) to enhance their Wifi coverage at home (and the product was registered in Taiwan). They were very pleased with the performance of the product and enjoyed having it very much, however, a few days ago the main router (RBR50) suddenly stopped working. There is no light at all even though the power is on. We tried different ways to resolve the issue such as cycling the power and resetting the system, but the issue remains and it seems to be a hardware issue.

Since the product is still under hardware warranty, we would like to obtain a replacement for it. Since the product was purchased in the US but registered in Taiwan, should my parents contact Netgear Taiwan for the warranty claim? Or should they bring the product to the US, and do the warranty claim in the US?

Thank you!
