IPTV: the sound plays but the screen stays black, what can I do?
Updated October 29, 2026
TIVERA has no message of its own for sound without picture: as long as playback keeps advancing, it shows no warning banner. Sound can play without a picture because the stream has no video (a radio), because your device's decoder cannot read the picture's format, or because the picture does not arrive from your provider. TIVERA tries another decoder by itself, but it has no decoder setting to offer you.
What you see on screen
While no video decoder has started, the screen stays black with the channel's logo and name (the title for a movie), surrounded by a loading ring, even if the sound is already playing. A radio never has a video decoder: it therefore stays on this screen. If the video decoder starts but shows nothing, the screen simply stays black. In both cases, the app does not tell you when it changes decoder.
What TIVERA tries by itself
- The hardware decoder first. The app plays the picture with the decoder of your device's chip. If it refuses the format, the app can switch to a software decoder (FFmpeg).
- A picture that does not come at opening. If data arrives but no picture has appeared yet after a few seconds, the app tries to rebuild the player: first with a fresh hardware decoder, then, if nothing changes, with the software decoder.
- A picture that freezes during playback (live channel). The app tries to rebuild the player with a fresh hardware decoder, never with the software one. During these attempts, the banner at the top may show “Reconnecting…”.
- Software is not a guarantee. It needs much more processing power than hardware, and on one TV box that was tested, its picture was unreadable. That is why the app does not use it during playback.
- If everything fails, an error card shows with Retry (see the table below).
What you can do, in order
- Wait a few seconds. The attempts above take time: the picture may arrive by itself.
- Leave the player, then reopen the channel. Each time the player opens, it starts from a new player, with the hardware decoder first.
- Compare. Try another channel from the same source. Then try the same channel on another device where TIVERA is installed: if it has a picture there, your device is probably the cause; if not, the stream probably is. Mind your subscription's connection limit: see error 403 and connection limit.
- Pick another version. If your provider offers several versions of the same channel, movie or series, the Quality row (in the channel preview or on the movie or series page) lists them: pick another one before you start playback.
- Try again. When the error card shows, tap Retry.
- Send a report. In Settings → System & Help → Send a diagnostic report, the app creates a .zip file with recent technical events, your device model and the Android and app versions, without your name, your e-mail or your server credentials. You choose where to send it.
Who decides what
- Your provider decides whether the stream contains video, and in what format (codec, resolution). TIVERA plays what it sends.
- Your device decides which formats its hardware decoder can read, and how much processing power is available for the software fallback.
- TIVERA decides the order of the decoders and the automatic restarts. It has no decoder setting: the Playback options window only offers audio, subtitles and speed.
Don't mix it up with these messages
| What you see | What it means |
|---|---|
| “The channel is not responding.” with Retry | The app received no data, or nothing it can read: neither picture nor sound has started. This is not sound without picture. See IPTV buffering or freezing and, to spot broken channels, test if channels are dead (Premium). |
| “The provider is refusing access to this channel. Check your subscription, or stop playback on another device.” | Your provider refused the stream. See error 403 and connection limit. |
| “Playback failed after N attempts. Tap to retry.” or “Can't play this. Try again or switch channel.” | The automatic restarts failed, including when a decoder cannot start. Tap Retry. |
Frequently asked questions
Why does a radio have no picture?
A radio is an audio-only stream: there is no video to show. Some lists mix radios in with the channels. TIVERA has no screen of its own for radios: the screen stays on the logo and name.
Can I choose between hardware and software decoding?
No. No setting allows it. The “Stream quality” diagnostic window, with its “Codec/Errors” tab that shows the decoder in use, only exists in development versions: it is absent from the published app.
Why doesn't TIVERA warn me that the picture is missing?
The app decides that playback is advancing when the picture or the playback position advances. With sound playing, the position advances: so it shows no warning banner. The messages in the table above concern playback that does not start or that fails.
