🎧 Introduction

Is your TV showing a clear picture but there’s no sound at all? You’re not alone. A No Sound Fault in TV is a common issue in LED, LCD, and Smart TVs across all brands like Samsung, LG, Abans, Mi, Nikai, and more. Whether it’s a hardware issue or just a wrong setting, this guide will help you troubleshoot and fix it step-by-step.

🧐 What Causes No Sound Fault in TVs?

1. Volume Muted or Low
   Sounds simple, but always worth checking first.
2. Wrong Audio Output Settings
   TVs with external sound systems might have HDMI/ARC or optical output selected instead of internal speakers.
3. Headphone Mode Stuck
   Sometimes TV thinks headphones are still connected.
4. Damaged Internal Speakers
   Physical speaker failure due to wear or electrical surges.
5. Software Glitch or Firmware Bug
   Especially common in Smart TVs like Mi, LG WebOS, or Android TVs.
6. Mainboard or Audio IC Failure
   If none of the above works, it may be a fault on the mainboard or sound IC.

🔧 What to Do If Your TV Has No Sound

✅ Step 1: Check Mute and Volume

• Use both remote and TV panel buttons.
• Ensure volume is up and not muted.

✅ Step 2: Inspect Audio Settings

• Go to Settings > Audio.
• Set output to TV Speakers, not external.

✅ Step 3: Restart the TV

• Power cycle: unplug from wall > wait 1 minute > replug.

✅ Step 4: Check HDMI or External Connections

• Disconnect soundbars, speakers, or HDMI cables.
