Xbox one System issue Need help asap

My Xbox one has a system issue. I get home from work and my Xbox is already on. I live by myself so no one could've turned it on. I always turn my Xbox off before I sleep. So whenever I got home my Xbox was turned on. I turned it back off then on again.
Only this time my Xbox won't display anything on the t.v I can power it on from the Xbox itself. I can also turn it on from the controller, however when the controller turns it on it starts blinking like it was never connected to my Xbox. And the only way
to turn it off is by holding down the power button for 10 seconds. So whenever my Xbox is on it won't display anything on the t.v and my controller won't connect to it. Ive tried switching HDMI cables, and also switching t.v's. I've tried hard holding the
power the power down for 30 seconds to hard reset and still nothing. I've also tried un plugging all the cords even from the power brick for atleast 15 minutes and still nothing. I've tried holding the power button and eject button to reset the resolution
and still nothing, I've tried everything and nothing seems to work. I've seen this happen to one other person and idk if they fixed theirs yet. I've only had the xbox for about 6 months and this is the third time it's happened. Xbox support doesnt help me
so I ask you the community to help. Has this happened to any of yall? I need a solution to this crisis ASAP. Like I said I've tried everything other than getting out the warranty, but that is a last resort.

Nothing else matters beyond what I said previously. Wherever you are logged in, you can play.

 

Help needed ASAP

Ok, Tesco have a deal on the xbox one S with Fifa 17 for £225 ... They have a voucher for £25 off any order over £150 .. So the Xbox will only cost me £199.. Il sell fifa for £30 .. So thats £170 for an xbox one S



However here is my issue. I game share with my brother on the current xbox one. I will be moving this upstairs as a media player and netflix player and keeping the One S to game on.


How does the game sharing work here? I know i can gameshare from my one S to my brother as normal. But what if i was ill and wanted to play inbed upstairs on my old console. What would i be able to play? Everything is stored on my external

 

Normally the Eject + Power button will force the display into the lowest resolution. The only thing I can think to try if that is not working is trying a different TV/outlet set and see if you can get the display to appear. If it does, go to your Settings,
Display & Sound, and change the resolution to the lowest one, then go back to your original TV, boot it up, then do the same thing to get the supported resolution for your TV that you want to use.

 

I've already tried this and still nothing. Why am I the only one with this issue
