If you are in the Academic Expansion in the Parkville Underground, go to the Extron Control Panel mounted on the wall near the Podium in the classroom.
Make sure the Display On/Off button is On. Next, if the AV Mute button is RED, press it again so the displays are not muted. You can also check to see if the Podium light is lit so it displays what is on the computer.
If the above does not seem to help, please call the Park ITS Help Desk at 816-584-6768 or 800-927-3024 and we will dispatch a Technician to your location right away.
