TV-Box not working
Follow these instructions to get your Swisscom TV-Box back up and running:
1. Check cables
Check whether all plugs and cables on the TV-Box, router and television are properly connected.
2. Restart your devices
3. Select correct HDMI channel
4. Press the “home” button
No sound
Turn up the volume using both the TV remote control and the blue TV remote control. If you use a sound system, do this there, too.
Tip: pair your TV with the blue TV remote control so that you only need one remote control.
