            When a problem occurs with the set-top box or the communication lines, screen images may appear with mosaic
            patterns.<br>
            The symptom can be addressed by initializing the set-top box.<br>
            ※ If the problem persists even after initialization, please contact your communications carrier for
            troubleshooting.

            1. Turn off your TV using the TV remote.
        </p>        <p class="txt-idt">
            2. Turn off the power switch on the back of the set-top box, wait for 5 seconds, and turn it on again.

        </div>
        <p class="txt-idt">
            3. If the set-top box does not have a power switch, pull out the power cord, wait for 5 seconds, and put it
            back on.

            4. If the power indicator on the set-top box flickers and then lights up, it indicates it has been
            initialized.
