Kinect Sensor Not stable

The thermal fuse is known to be twitchy. The fan has likely failed. Microsoft is not repairing them any more.

To make sure the Kinect doesn't fall off the TV, I would probably put it somewhere closer to the ground, such as on a table or other surface elevated off the ground, but under the TV. Then, the Kinect will be able to see you when you face the TV, without
risking placing it on top of a thin TV.

The support article says:

• Place the sensor near the edge of a flat, stable surface.
• Position the sensor between 0.6 m (2 feet) and 1.8 m (6 feet) from the floor, the higher the better. Ideally, the sensor should be within 15 cm (6 inches) above your TV.
  
• Avoid positioning the sensor in direct sunlight or within 0.3 metres (1 foot) of audio speakers.
  
• Place your Kinect as close to the edge of the surface it is sitting on as you are comfortable with, and make sure that no other nearby objects are obstructing the field of view.
  
• Do not place your sensor directly on top of the console.
• Be careful not to drop the sensor.

To play the Kinect games released on the Xbox 360, you will have to play them with an Xbox 360 console with the Xbox 360 Kinect Sensor.

The Kinect Sensors are not interchangeable between consoles (you cannot use One Sensor on Xbox 360, nor a 360 Sensor on Xbox One), as both Kinect Sensors have different, proprietary Kinect plugs, and the games are specifically programmed to use the exact Kinect
sensor on the console they were released on.

Your Xbox One Kinect Sensor won’t turn on

If you’re having trouble with your Xbox One Kinect Sensor, verify that the sensor is turned on. You’ll know it’s on if the Xbox logo on the front of the sensor is lit.

If the Xbox logo on the front of the sensor is not lit, or it’s lit but your console says the sensor is disconnected, follow the troubleshooting steps on this page.

Notes

• If your Kinect sensor turns on without any errors, but you’re still having trouble with it, see Troubleshoot issues with the Xbox One Kinect
  Sensor.
• If your Kinect sensor is plugged in and turned on, but there’s no video in Kinect settings, see Kinect sensor
  isn’t recognized by your Xbox One S or original Xbox One console.

Hi there,

if you have tried all trouble shooting steps mentioned on these links:

support.xbox.com/.../kinect-sensor-wont-turn-on

support.xbox.com/.../kinect-sensor-not-recognized-by-console

Then the only option left is to have to Kinect sensor repaired like mentioned on the links. You can set up a repair via

The Kinect sensor itself transmits the commands to power the TV and audio systems on and off and because the sensor isn't working they won't be powered on and off.
