Hi Steven, it seems that your HD Box is indeed at the end of its life. I would call the hotline 0800 800 800 and ask for a replacement (the HD Box is the property of Swisscom whilst all the later ones must be purchased) but if you talk to them, possibly, you‘ll get a UHD Box (IP 1400) as replacement or at least a good offer for the IP 1800 or IP 2000. Just try it 😎. Or if you have a smart TV which supports the blue tv app, you could use the app without a box. Either way, good luck!
