The green light on top of my Xbox X

The One X or Series X? Either way, there's not a green light. The only light on the console is the power button which should be white.

It’s green paint or plastic. There is no light.

ya i just got the same issue just moved my x box upstairs and played then back down and it does the same thing as yours green light in middle on tray opens no wide green light and controllers wont sync. let me know if you got an answer

To connect one controller, first insert the batteries. Then, press and hold down the xbox symbol on the controller. It should then light up green. But, if you're trying to connect a second xbox controller, on your console there should be a button on top
of the memory card insert place near the bottom of the xbox, below the green power switch. Press it, then on the controller you are trying to connect, press the xbox button. It should then light up.

The light on my psu is green, the light on my xbox turns off instantly
