How do I get to the troubleshooter screen

Good evening,

This is a very vague question. I don't know if your console is functional or not. Let me know of some more details if you can.

For now, this is the official way to get to the troubleshooter screen (from google):

You can bring up the Xbox Startup Troubleshooter on this console by holding only the Pair button (steps 3 and 4) and then pressing the Xbox button . Continue holding the Pair and Eject buttons for 10-15 seconds. Listen for two “power-up” tones a couple of seconds apart.
