You can try the maintenance reset that does not erase your recordings, but beyond that TalkTalk have not made these boxes for a while now.

Don’t worry, there are plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here How to contact TalkTalk Broadband - TalkTalk Help & Support
