Easy First Steps to Try

Before diving into more complex troubleshooting, start with these basic Toshiba TV audio fixes:

1. Check Volume Settings

You can also try pressing the menu button and ensuring all audio settings are enabled and set to appropriate levels via the settings menus.

2. Inspect All Connections

Loose cables or ports can cause loss of audio signal.

  • Check that cables connecting external devices like a cable box, DVD players, or game consoles are fully plugged into the ports on the back of the TV.
  • Reseat connections by unplugging and firmly plugging cables back in.
  • Inspect cables for any damage which could disrupt sound.

HDMI and optical/TOSLINK cables are commonly used for TV audio. If possible, swap suspect cables for a reliable spare.

3. Power Cycle the TV

Quickly power cycling can clear any temporary software glitches causing sound problems.

  • Unplug TV power cable from electrical outlet.
  • Wait 30 seconds.
  • Firmly plug power cable back in.

After restarting, check if sound returns. If not, continue troubleshooting.

Advanced Troubleshooting Tips

If you’ve tried the basics with no luck, working through these steps methodically can help identify and resolve the root cause.

4. Run Audio Tests

Determine specifically where the audio failure is occurring – the internal TV speakers or external home theater system.

  • Try alternate audio sources like built-in streaming apps, Blu-ray player or gaming console to isolate the issue.
  • For external home theater connections like a sound bar, disconnect and rely on native TV speakers alone.
  • If TV speakers aren’t working but external audio is, internal speakers may be damaged and need service.

Narrow down the source of no sound to guide your troubleshooting.

5. Adjust Audio Settings

Incorrect TV audio configurations can cause various problems.

  • From TV settings menu, reset Sound options like mode, balance and digital output to default factory settings.
  • Disable any advanced adjustments like virtual surround or equalizers.
  • Check secondary audio options for unwanted settings – audio should be set to main program language.
  • For external speakers, enable options like HDMI-ARC and S/PDIF optical outputs.

Restore simple, base functionality first before testing more complex configurations again.

“After my Toshiba TV suddenly had no sound, going into audio settings and changing digital output from Bitstream back to PCM output instantly fixed it.”

6. Update TV Firmware

Outdated firmware can introduce bugs leading to loss of sound.

  • Navigate to About > System Update menu.
  • Check for any available updates online and install latest firmware for TV model.
  • Allow update to complete and reboot TV.

7. Switch Input Sources

The simplest connectivity issues can have serious impacts.

  • If using a secondary device like a Roku or Blu-ray player, check it is powered on and paired correctly.
  • For cable or satellite boxes,verify all feeds and outputs to TV function properly.
  • Swap HDMI inputs and cables connecting devices to TV to test different ports.

8. Factory Reset TV

Resetting Toshiba TV settings to factory default can fix sound problems stemming from damaged software or incorrect configurations.

  • Power on and access TV settings menu.
  • Select Preferences > Factory Reset everything.
  • Confirm reset and allow TV to reboot.

This completely reinstalls TV software assets which resolves many audio issues. Note you will have to reprogram any custom settings afterwards.

“No sound on my new Toshiba TV was fixed after I performed factory reset from settings menu in less than 5 minutes without calling for service.”

9. Replace Damaged Cables

Inspect wiring connecting external audio equipment like sound bars for any damage.

  • Swap HDMI or optical TOSLINK cables connecting your sound system.
  • Try cables on another device setup first to confirm them as working.
  • Secure cables to prevent pets or children chewing on them.

Cabling issues can appear randomly even after functioning normally previously. Substitute any questionable cables.

10. Rearrange Devices

Electrical interference from nearby equipment can disrupt audio signals.

  • Try moving TV away from potential sources like wireless routers, microwaves, or baby monitors to clearer transmission.
  • Position audio devices like wireless speakers or sound bars closer with fewer obstructions between components.
  • Angle antenna to optimize signal strength.

Carefully relocating your setup can improve stability of all connectivity.

11. Install a Signal Amplifier

In cases where no sound persists even after addressing other issues, a signal booster can enhance the audio input.

  • HDMI audio extractor splits HDMI signal, converting video input to HDMI output to TV while passing audio via RCA or optical output to speakers.
  • Signal boosters for coaxial audio cables can also bump sound to an optimal level.
  • Amplified splitters for antenna feeds likewise keep audio transmission strong.

While not an ideal long-term fix, quality in-line amps can quickly get audio functioning again in a pinch.

12. Get Professional Service

For recurring sound problems or complications after trying these fixes, seek expert help. Qualified service technicians have specialized knowledge and resources to fully diagnose no sound causes.

  • Contact manufacturer support to troubleshoot or avail warranty repairs if TV under coverage.
  • Take set into electronics repair shop for hands-on assessment by service staff.
  • Schedule in-home visit from TV repair pros if unable to transport large set.

Though home troubleshooting resolves many audio issues, professionals can test components like power supplies, mainboards and screen backlights unavailable to consumers to pinpoint faults.

“After my Toshiba TV’s speakers failed, the repair shop discovered a blown capacitor on the mainboard was the culprit. A $60 part swap by their technician got the sound working perfectly again.”

Preventing Future Toshiba TV Audio Problems

While even reliable Toshiba televisions can suffer from sound disruptions on occasion, following best practices helps avoid problems:

  • Leave adequate ventilation space around TV to prevent overheating.
  • Use surge protectors to safeguard sensitive electronics from voltage spikes.
  • Keep TV and connected equipment free of dust, moisture and contaminants.
  • Position components securely to avoid cable strain and accidental movement.
  • Update firmware and apps to maintain compatibility with evolving standards.

Stay proactive with basic preventive maintenance steps for a smoothly functioning home theater setup.
