Highly doubtful. The HDMI port is soldered onto the main board of the Xbox. It would be too much liability and work for them to take on this type of service. You can get a replacement XBOX One on Craigslist for less the hassle and cost. Good luck.
Yes you can... They have customer service zone... You need to ask over there... If you have bought the Xbox from them then, they should do it. If not, then they might ask you to pay for the service.
