Toshiba TVs No Sound: How to Fix It Yourself
No sound from your Toshiba TV is usually a settings issue — muted volume, wrong audio output, or disabled speakers. Hardware speaker failure is rare.
⚠️ Safety First
- Unplug the TV before inspecting internal speakers.
Parts You May Need
Step-by-Step Repair
- 1
Check the obvious settings
Make sure the TV isn't muted (press Mute on the remote). Turn the volume all the way up. Check if the TV is set to output audio to external speakers that aren't connected.
- 2
Check audio output settings
Go to Settings > Audio/Sound. Make sure the output is set to "TV Speakers" and not "External Speakers," "ARC," or "Optical." If you have a sound bar, make sure it's powered on and set to the correct input.
- 3
Test different input sources
Switch between HDMI inputs, antenna, and streaming apps. If some sources have sound and others don't, the issue is with that specific source, not the TV speakers.
- 4
Power cycle the TV
Unplug the TV from the wall for 5 minutes. This resets the audio processor and clears software glitches. Press the power button on the TV while it's unplugged to drain residual power.
- 5
Factory reset audio settings
Go to Settings > Audio and reset to defaults. If that doesn't work, try a full factory reset (back up settings first). Corrupted audio settings are more common than speaker failure.
If That Didn't Work
- HDMI ARC/eARC cable not supporting audio pass-through
- Broadcast channel audio issue (not your TV)
- Internal speaker wire disconnected
When to Call a Professional
If the TV has no sound from any source after a factory reset, the internal speakers or audio processor board may have failed. Speaker replacement is usually $30-$60 at a repair shop. A sound bar ($30-$100) is often a more practical solution.
