      I have an Activeboard (Product Code ABV 587PRO )that randomly shuts off.  The projector is fine.  I have checked to make sure that all updates for the driver are taken care of.  There seems to be no pattern to when it shuts off.  Sometimes, it is in the middle of being used.  Other times music is being played through the speakers.  Every time it does this, it needs to be recalibrated.  Any suggestions as to what may be causing this problem?

      Hi pmengler,

      Thanks for posting on the Support Community.

      With regard to the shutting off, could you advise what happens to both the LED on the top left of the ActivBoard and the LED on the amplifier on the left hand side?
      When this goes off, what happens to the computer? Is the ActivBoard detected within ActivManager Control Panel?

      I would suggest ruling out any cabling issues, could you connect a short known working USB cable directly to the USB port on the bottom left of the ActivBoard as per the diagram below bypassing any wallboxes or faceplates that may be in use.

      I hope this helps.

      Kind regards,
