I went to a repair shop “ubreakifix” for my xbox series x because it would not turn on at all. I gave them the xbox but a week after I got a call saying they cannot fix it because it is a motherboard issue but I find this hard to believe because I have had this xbox less than 2 years while my xbox one I’ve had for 7-8 years has never had any problems. Do you know what’s the next step to fix this?
