[LG TV] Popping or Ticking Sounds from TV

Troubleshooting TVS/SOUNDBARS 11/05/2025

<li>When the TV is powered on, its internal components heat up. This heat causes the outer casing, made of specialized plastic material, to expand.<br>
As the different parts of the casing expand, friction can occur, creating clicking or popping sounds.<br>
This is known as thermal expansion noise.
</li>

<li>To eliminate thermal expansion noise, the product would need to be made of a single, uniform material that does not create friction during expansion. <br>
However, it is extremely difficult to manufacture complex electronics entirely from a single material.</li>

<li>Thermal expansion noise is also commonly heard in furniture, sinks, and cars, and do not indicate a malfunction. <br>
The sound may be more noticeable depending on the season, room temperature, humidity, how long the TV has been used, and product size.  
In many cases, the sounds become less noticeable over time.</li>
</ul>
<p>※ The sounds may be more noticeable in high humidity. Keep this in mind if you use a humidifier near the TV.</p><p class="help-txt">
