Restart the app and playback device
Fully close the app and power-cycle the TV or streaming device.
Test another HDMI port and cable
Bypass a receiver or splitter for one test.

Protected playback may intentionally show a black image.

Focus on the app, protected playback, device software, or title session.
Focus on the cable, port, receiver, input, or display handshake.
A DRM, HDCP, app, or video-mode issue is likely.

Frequently asked questions
Why can sound play when video is black?
Audio and video are separate paths. The app can decode audio while protected video output or rendering fails.
Can an HDMI splitter cause this?
Yes. A splitter or receiver that does not complete the required HDCP handshake can block protected video.
