I plan to sell my Xbox and all its accessories, including the Xbox Kinect
The problem here is that when I plug the part in, it turns on and then turns off again.
It goes on all the time.
According to the Xbox, I should restart the console a couple of times, but it's still the same as before.
Do you have some advice on how I can fix this problem because it was really expensive.
A well-known problem, which is most likely caused by overheating or a fan.
https://www.reddit.com/...n_its_own/ even someone says that it helps if a certain cable is cut. Everyone has to decide for themselves whether this is a good idea.
So my Kinect goes on but the fan doesn't turn at all then the part goes off again
Yes, that will be the cause. Too much heat is generated and it is automatically switched off.
