Checking for Open Loop on Multimeter - Xbox one s doesn't turn on

Hi. I recently bought a broken xbox one s that coulnd’t turn on. I wanted to check the power and ground pins, but my multimeter doesn’t have the setting that TronicsFix has on his videos.
How can I check that?
And does somebody know what the problem might be?
Do you think I have to order a new power supply?
How can I test if the power supply is good or bad?
Thank you for anyone who will answer me.

Can you show image of your multimeter and its settings?
