[LG OLED TV] Troubleshooting: Double Image (Ghosting)

Troubleshooting TVS/SOUNDBARS 08/14/2025

<h2 class="tit">Causes and Symptoms</h2>

<li>The set-top box connection is poor.</li>
</ul>

<h2 class="tit">Let's find out more.</h2>
<p>
Double image on a TV screen connected to a set-top box may be caused by a poor HDMI cable connection. <br/>
If double images only appear on certain channels, it is likely due to a broadcast signal issue rather than a problem with your TV.
</p>

<h2 class="tit">Try this.</h2>
<p>
Perform a Picture Test to check for issues with your TV.<br/>
If the test image displays correctly, the issue is likely with your broadcast signal, not your TV.<br/>
If that is the case, please contact your service provider (Cable, Satellite, IPTV, etc.).<br/>
If the test image does not display correctly, contact LG customer support for assistance.
