Thank you for posting on the Answers Forum. I see, you're having problems with your Slingbox only getting audio but no video.
Fortunately, a No Video Signal error, shown below, is relatively easy to fix. It is usually caused by one of these issues:
- Your video source isn't powered on.
- Your video source isn't properly connected to your Slingbox.
- Your video signal is blocked by a form of copy protection called SOC, or Selectable Output Control. Look below for more information.
