Steps
Check whether audio is playing with no video
If you hear sound but see a black screen, this usually points to a video decoding or HDMI signal issue rather than a network problem — different fixes apply than for a fully unresponsive screen.
Try a different channel or stream
If only one channel shows a black screen while others play fine, the issue is likely with that specific stream source, not your setup.
Restart the app
Fully close and reopen the app (not just navigate back) — this clears a hung video decoder session, a common cause of a persistent black screen.
Check your HDMI connection and cable
A loose or faulty HDMI cable can cause a black screen with intermittent audio. Try reseating the cable or testing a different one if available.
Update the app to the latest version
Video decoding bugs are commonly fixed in app updates — check the app store for a pending update if the issue persists across multiple restarts.
Try a different video player/decoder setting if the app offers one
Some player apps let you switch between hardware and software video decoding in settings — toggling this setting resolves black-screen issues on certain device/app combinations.
Troubleshooting
The screen goes black only on 4K channels
This often points to an HDMI handshake or HDCP compatibility issue between your device and TV/receiver at higher resolutions — try a lower-quality stream option, or check that your HDMI cable is rated for the resolution you're trying to play.
Black screen happens right after an app update
Occasionally a specific app update introduces a playback bug on certain devices. If this coincides exactly with an update, check the app's support channels for known issues with that version.
