My Xbox was absolutely fine the all of a sudden it stopped working so i got a repair and it was fine then i noticed a problem the front turn on button didn’t work and the button to connect a controller didn’t work either. Now i cant get it turn on at all ive tried using my controller the power button, I EVEN TRIED MY PHONE!!!!! So i don’t know what else to try.

the power button is damaged, the repair place sometimes just fixes the component without replacing it , it really makes me mad, so you might need to replace the power button , connector, or if neither works replace the power supply.
