What to do if there is no picture or no sound on my BOXLIGHT ProColor 652U?

If your BOXLIGHT Gateway displays no picture or sound, first ensure the display is powered up. Then, confirm the video input cable is properly connected and selected. If you are in internal computer mode, verify that the internal computer has started.
