Smart TV app has video but no audio starts by locating the failure and confirming the device that runs the app. Follow the questions in order; later steps depend on your answers and may affect sign-in or settings.
Confirm the exact device and platform. Use low-risk checks first. App availability, firmware version and root cause are not assumed from a brand or series name.
What to establish first
- Can you still reach the TV’s Home screen and use its remote?
- After this step, is the original issue fixed?

Low-risk checks you may see
The next action depends on your answers. These are possible steps, not an instruction to perform every one.
Check whether another app works Information check
- Open a different streaming app.
- Play a short video if possible.
- If the other app works, investigate the original app first; if all apps fail, test the network and TV system.
Separate audio problems from app failures Information check
- Check whether built-in TV apps and antenna/HDMI sources have sound.
- Check TV mute and external receiver/soundbar volume.
- If only eARC/CEC audio fails, follow exact TV and soundbar manual.
Restart TV/device via Settings if available Reversible
- Use the TV’s Restart control, not only sleep/standby.
- After the TV restarts, open the app again.

How to check your exact setup
- Can you still reach the TV’s Home screen and use its remote?
- Answer each question using what the TV or HDMI device actually shows; correct the device layer or OS before accepting its menu instructions.
- If a step may remove accounts or settings, read the impact and the exact manufacturer instructions; stop the flow when a safety warning appears.

When to get more help
If the issue persists after the safe checks, use the TV maker for power, display and system faults; the app provider for a single app or account; and the internet provider for a network-wide outage. An app or model-specific compatibility decision needs the exact SKU and a current official source.
