Sometimes when I turn my 360 on it straight away gets the 3 red lights but sometimes it turns on and works a few minutes before it just locks up and becomes unresponsive (without 3 red lights). Other times it will work for over an hour without fault. Will I have a problem if I send the 360 back to be repaired and they seemingly find nothing wrong with it? I have a photo on my phone of it with the 3 red lights but I'm not really sure if that's good enough proof if they needed it.
Anyone been in a similar situation?
