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

How to initialize a set-top box
1. Turn off your TV using the TV remote.
2. Turn off the power switch on the back of the set-top box, wait for 5 seconds, and turn it on again.
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.
※ The initialization method may differ by the model of the set-top box.
This guide was created for all models, so the images or content may be different from your product.
