Hi,
I posted this on your duplicate thread which you might like to try.
Have you sent the old one back yet?
If not then unpair the new one and then pair the box with the old remote.

Did that work?
If not try resetting the box to factory settings and hopefully it will then work.
From the 29th of March our TalkTalk Community will move to peer-to-peer support and the TalkTalk team will no longer be here to support with queries. Don’t worry we still have plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here:
