Our recommendation

Check your Swisscom connection online

TV-Box picture and sound problems are often related to your Swisscom connection. Log into the My Swisscom Customer Center and check whether there is a problem on your line. You can also get step-by-step technical support there.

We will also inform you about current faults and maintenance work at or via the My Swisscom app.

Fix blue TV problems manually

There are various reasons why your Swisscom blue TV picture or sound may be interrupted, distorted or frozen. Check your Internet connection, your TV settings and your provider’s TV box.


The following steps may solve the problem:

  • Check the cabling

    Check whether all the plugs are correctly connected to the router, the connection kits, the TV-Box and TV set. Remove and reconnect all plugs.

    Disconnect devices from the power

    Disconnect any connection kits from the power for 10 seconds; after reconnection, wait until the kit is ready for operation again. Reboot the router and then the TV-Box.

  • Select the HDMI channel

    Select the HDMI channel on your TV set. Look for the correct button on your TV’s remote control to switch to the AV channel (not the TV-Box remote control). Refer to the user guide for your TV set to identify the right button.

    Press the “guide” button

    Press the “guide” button once on your blue TV remote control. The TV-Box will then transmit a picture that you will immediately recognise as the blue TV picture.

If you are using the blue TV app on your TV (with Smart TV  currently Samsung from 2017, further devices to follow

) or with an external provider’s TV box, contact your provider or TV manufacturer direct.
