Xbox One Xbox turns on but won't do anything

[ComaKing505]

I just got a OG Xbox one (2014 if that matters at all) with the green screen of death and I just got that fixed but I put it back together and now it turns on the light on the front, the fan, and the hardrive but won't do anything else. not even the green screen of death anymore. I tried to open the troubleshoot screen but it crashed a few second after turning it on. I tried everything I can think of but nothing works. Also this isn't related to the post at all but my username is actually CamoKing505. ComaKing505 is a typo LOL
