HeroMagic wroteSo my Xbox one won't boot up. I've tried switching HDMI around and using a different HDMI. Tried a different power brick and everything. Tried turning it on while it's on it's side, nothing works. So basically what happens is I press the power button to turn it on it makes the Xbox chime but then my TV says no signal and the Xbox light stays on for a bit until after a while (4-8 minutes) it makes the Xbox chime and shuts itself off. Would really hope to figure out how to fix this because my warranty is out n I'm broke. So anyone please try and help me. I will +rep. Ohh and when i try to start in low resolution mode nothing happens it won't make any nosies or anything just sits there with the light on.
What kind of power brick do you have? OEM or off brand?
Also, when have you previously played on your Xbox One before it started to mess up and did you install a update?
