What you can do
Check that all cables are plugged in correctly. Then start the Sunrise TV Box by unplugging it and plugging it back in after 10 seconds. Wait until the box has completely restarted, then check whether the problem has been resolved.
Please check whether you have accidentally muted your TV or if the volume is set too low.
If you have a home cinema and are using an AV (audio video) receiver, please check the relevant connection. The best way to do this is to follow the instructions for your home cinema system to make sure that the receiver is connected correctly.
Connect your Sunrise TV Box directly to your TV set via an HDMI cable. This means that no other devices (such as an AV receiver) may be connected intermediately.
