Soft sounds, orange light on power brick, but not turning on.

Hi all,

My Xbox One is suddenly not turning one. I can hear the beep, but it is very soft. Same with the disc eject. Power brick has an orange light showing. Have tried multiple different reset options shown here, but nothing. I don't THINK it overheated, all the vents are clear of dust, its well ventilated (when it was still working!), has not been wet or bumped.

Really need to get this working if possible, has all our subscribed services on it, nevermind the games and the game disc still inside!

PLEASE HELP!!
