MacBook Pro 2016 going to sleep after one minute no matter what my settings are

My first instinct would be to reset the SMC.

Resetting the SMC

To do this on your particular MBP, follow these steps:

1. Shut down your computer
2. Keep the power cable plugged in.
3. Press at the same time shiftoptioncontrol (on the left side of the keyboard) and the power button
4. Let go
5. Turn your computer back on with the power button.

Also, you should probably reset the NVRAM as well.

Resetting the NVRAM on Late-2016 MacBook Pro models

For all Late-2016 MacBook Pro models (with and without Touch Bar) follow these steps:

1. Shut down your machine. Yes, a full shut down, not just logging out.
2. Press the power button and then immediately press the commandoptionpr keys.
3. Keep these keys pressed down for at least 20 seconds!
4. Let go of the keys and let your Mac reboot normally. Note: When you log back in you may need to readjust some of your system preferences (e.g. speaker volume, screen resolution, startup disk selection, time zone information, etc). Let me know how you go.

[EDIT - Screensaver]

Since resetting the NVRAM and SMC have had no effect, perhaps you should check your Screensaver settings to see if it's kicking in after one minute? To check this:

• Go to Apple menu > System Preferences
• Select Desktop & Screen Saver
• Click on the Screen Saver tab
• Check when it is set to start
