If the HDMI cable connection is bad or set-top box broadcasting signal is weak, then the screen display can freeze, flicker, get cut or broken and so on.<br/>
In this case, ask the service provider and check the broadcasting signals [Wired, Cable, Skylife, IPTV and etc].
</p>

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

<li>The signal cable connection condition is poor.</li>

<li>The environment setting for the TV monitor is changed.</li>
</ul>

<h3 class="sub-tit">Is the cable connected properly?</h3>
