same thing here, happened a few days ago.
I live in the EU and all products must have a legal waranty period of 2 years, regardless of what the producer/seller states in their contracts.
I will certainly contact EU Customer Support to tackle this problem of Microsoft not responding to customers about failing hardware.
If I have news, I'll post it here...
As I thought: I bought the product in May 2017, so I'm covered until May, 2019.
I've requested a repair from the (re)seller of the product.
