Hi, I just got a HD Slingbox and i am trying to put together the coaxial cable but i see a black screen with good audio. I conect using the composite cable and it is working perfect. What should i do?!
You need to confirm that the input is properly selected and that you scanned all the channels during the Setup Assistant. If the issue persists, I'd recommend to Reset the Slingbox to factory settings and run the setup once again.
