I Can't See Video But Can Hear Audio

Are you getting a Black screen while attempting to play your streaming apps, especially on Apple TV? Then this may be due to a fault with your HDMI cable which can result in the HDCP handshake between your TV and Apple TV to go wrong. Somehow the Apple TV loses its ability to output HDCP content after some period of time.

You can get around this problem by restarting your device and/or TV or replacing your HDMI cable with a new one.
