When a Samsung TV no audio but picture works situation occurs, it narrows the fault down considerably, since the TV's core electronics and display processing are clearly functioning. This specific combination of symptoms points to a handful of likely causes.
Likely Causes
The most common cause is the TV being set to output audio to an external device, such as a soundbar or AV receiver, that is either off or disconnected. A muted TV, sometimes triggered accidentally by a universal remote, is another frequent cause. HDMI ARC or eARC misconfiguration can silence internal speakers while leaving the picture unaffected. On the hardware side, a failed audio amplifier chip or damaged internal speaker wiring can cause this exact symptom, since picture processing and audio processing run through largely separate circuits on most Samsung boards.
Troubleshooting Steps
Check Settings > Sound > Sound Output first, ensuring it is set to Internal TV Speaker if no external audio system is connected. Unplugging any HDMI-connected soundbars temporarily can help confirm whether ARC settings are the culprit. Restarting the TV resets the audio subsystem without affecting picture processing. If Samsung TV no audio but picture works persists after these checks, the fault is very likely a hardware issue with the internal speakers or audio amplifier, which requires a technician to open the TV and test components directly.

Frequently Asked Questions
- Why would my TV lose sound but keep a perfect picture? Audio and video are processed on largely separate circuits, so an audio-specific fault does not affect picture quality.
- Could a recent software update cause this? Yes, updates sometimes change default audio output settings, silencing internal speakers unexpectedly.
- Should I try a factory reset first? It is worth trying settings adjustments and a restart before a full factory reset, which is a more drastic step.
- Is this a common fault on older Samsung TVs? Yes, ageing internal speakers and amplifier components are more prone to failure after several years of use.
- Can this be fixed without replacing the whole speaker unit? Often yes, if the fault is a loose wire or connector rather than a fully blown speaker.
