Xbox One S chimes, but won’t power on?

Neither the step by step, or using a different power cable helped. It is still acting as it did in the video. I do hear the disc eject sound though, then it turns itself off

Si tienes garantía puedes mandarlo con xbox y te pueden dar otra nueva, pero si no tienes garantía puedes abrirla y limpiar los componentes y mirar si todo está bien dentro de la consola

Unplugged it and came back to it after about 10 minutes. Still acting the same as the video

Try this first:

Power off your console, and then unplug the power cord to ensure that the console is completely powered off.

2. Wait 30 seconds, then plug the power cord back in.

3. Press and hold the BIND (controller sync button located on the left side of the console or bottom right if a one S or one X) and the EJECT button and then just press the Xbox button on the console once.

4. Continue holding the BIND and EJECT buttons for 10-15 seconds.

5. Listen for two “power-up” tones a couple of seconds apart. You can release the BIND and EJECT buttons after the second power-up tone.

6. The console should power up and take you directly to the Xbox Startup Troubleshooter.

7. To reset your console from the Xbox Startup Troubleshooter, use the D-pad and A button on your controller to select Reset this Xbox.

9. When prompted, select Keep games and apps. This option will reset the OS and delete all potentially corrupted data without deleting your games or apps.



Then, try different power cable and different power outlet. Please, let us know if this helps.

Then try this:

To reset the internal power supply, follow these steps:

1. Unplug the power cord from the console.
2. Wait 10 seconds.
3. Plug the cord back into the console, and then press the Xbox button  on the front of the console.

If the console turns on, the internal power reset worked. Do this step if the problem happens again.

If nothing helps, I'm afraid it is a hardware failure. Also, try to leave it unplugged for some time. Then try again. So sorry....
