I have been using my new Xbox for over a month with no change to any settings since I set it up. I played on it last night with no issues and turned it off. I tried to turn it on today and I got no video signal, but I got audio through the optical cable. I tried multiple things to isolate the issue, but to sum up the most telling tests I used two different HDMI cables and two different hidef TVs with the same results, no video signal. In using the different tvs I had to physically unplug the Xbox One and move it to a different room so I have also forced a complete power off and power on.
Through this process of elimination I have narrowed the problem to the HDMI Out not sending a signal, but I am now at a loss as to what to do about it. Any help would be appreciated.
