Set up my new Xbox one last night. All working fine. This morning when turned on the display would come on then go black then come back on then go black and it keeps doing this.
The sound is not effected.
I have tried wiggling and taking out and putting back in the HDMI cables. I tried lowering the screen resolution to 720p.
My console is plugged into my Sony TV via a Sony surround sound system and a sky+ HD box is plugged into the console for TV.
