Well, yet another customer who was sent a replacement box, only for it to fail at 33% channel info.
When you consider that this fault has been apparent for many years, yet no apparent solution or software upgrade to avoid at point of installation.
I'm sorry you are having issues.
It's doing that because the box hasn't been activated yet.
You need to call 0800 953 9500 to activate the box.
You will need the box serial number, and your account number and area code.
